8. Menu System
The Main Display on the front panel of the TDA 2200 shows all functionality and current
status of the TDA 2200. An overview of the menu tree can be seen in the appendix.
When the amplifier is powered up the Main screen shows the current Software revision in
the Startup picture as:
After showing the initial screen, which can be used to identify the software version, the
main screen is shown.
Furthermore the Volume Control is set according to the standard settings which can be
altered in the menu system
In the display the current setting of RoomPerfect™, the voicing setting and the sample
frequency of the input are displayed. If a digital input is active the source sample rate is
detected and displayed. If the Analog option is mounted and selected the ADC sample rate
96 kHz will be displayed
Pressing the Menu button on the remote or the front panel access the top level of the
Menu system
Using the Left/right keys the Menu system settings can now be scrolled through. To
access a sub menu setting just scroll to it press the Enter button. The Sub menus
accessible in version 2.1 are:-
• RoomPerfect™
• Voicing
• Cross-over
• Delay
• ADC Level (Optional)
• Communication
• Trigger Set-up
• Remote Control
• Display
• Volume
• Advanced Set-up
The above options are described in detail as follows.
14

a. RoomPerfect™
The sub menus accessible in the RoomPerfect™ menu are:
• Guided set-up
• Advanced options (available when Guided set-up has been performed)
RoomPerfect™ and the sub menus are described in-depth in the RoomPerfect section,
page 19.
b. Voicing
The Voicing setting is an EQ filter that can be used to gently amplify or attenuate certain
frequencies according to your personal preferences and/or to compensate if a given
recording sounds too ‘bright’ or too ‘dark’. There are 7 settings in all: Neutral, Soft 1, Soft
2, Open 1, Open2, Desharp1 and Desharp2. The frequency curves of the different voicing
settings can be viewed in the appendix. Neutral is a bypass setting.
When using RoomPerfect™ you will experience a much more precise and detailed sound
reproduction – which could also be described as more analytical. This means that it’s easy
to distinguish poor quality recordings. In this case the voicing feature can also be used
with great benefit to e.g. attenuate a “harsh” midrange with the Desharp1 or Desharp2
filters.
c. Crossover
The sub menus accessible in the Crossover menu are:
• Select Crossover
• Crossover Frequency (available when crossover has been selected)
The crossover filter is chosen when you wish to use a subwoofer – or the Lyngdorf corner
woofer configuration – together with your main loudspeakers.
If NO is selected the full frequency range will be directed to your main loudspeakers. If
YES is selected only frequencies above the selected crossover frequency will be directed
to the main loudspeakers. Frequencies below the selected crossover point will be directed
to your subwoofer(s) through the analog line-out and will also be available on the digital
output terminals.
15
Download from Www.Somanuals.com. All Manuals Search And Download.
The crossover frequency can be selected anywhere between 40 – 400Hz.
Due to the limited frequency response of most conventional subwoofers we do not
recommend that you select a crossover frequency higher than 80 – 160Hz.
However, with a Lyngdorf Audio 2+2 system you can go as high as 400Hz! Please study
our literature on 2+2 systems or visit our website, see the Support section in this manual.
d. Delay
If you are using a set-up with two main loudspeakers located at an identical distance to the
listening position you don’t need to set a delay. However, if the distance isn’t identical
and/or you are using a subwoofer or a Lyngdorf Audio 2+2 system, you can set a delay in
order to ensure that the sound from each loudspeaker reaches the listening position
simultaneously. This must be done for main left (ML) and right (MR) and, if subwoofers
(sub) are used, also for the line left (LL) and right (LR).
To set the delay all you need do is to measure the distance from each loudspeaker to the
listening position and enter these values in the menu. The necessary delays are then
automatically calculated and applied to each channel.
The above error message is displayed when the entered distances for either channel
(Left/Right) exceed the maximum possible delay in the TDA 2200.
Solutions:
(Can be used individually or together to achieve a valid set-up with respect to the delay
lengths):
• Shorten the distances between your Main and Line channels resulting in a more
compact loudspeaker set-up.
• Arrange your loudspeaker set-up and/or your listening position in a more
symmetrical set-up.

e. ADC Level - Otional
The ADC Level menu is accessible when the optional analog input module (A/D converter)
is installed. Here it is possible to choose between the inputs on the analog input module
and assign each input a LOW and HIGH level. When the LOW level is selected no
amplification of the analog inputs is performed, whereas when the HIGH level is selected
an amplification of +6 dB is performed.
f. Communication
The sub menus accessible in the Communication menu are:
• Comm Speed
• Comm Address
The Communication setting signals the TDA 2200’s identity to the PC interface or other
Lyngdorf products. In master mode the amplifier setting is normally 1, and the addresses
2-99 can be used for individual slave amplifiers, but nothing is restricted. In the menu the
current address and the new address is shown, The Up/Down keys can be used for
changing the new setting, and a new selection is stored with Enter which also exits the
menu again. Pressing Menu again exits the menu without changing the current settings.
The PC software must know the address of the TDA 2200 in order to communicate with it.
The Comm Speed setting is the RS232 Link interface speed. The default setting is 57600
baud. With different PC’s and different lengths of cables the settings can be changed for
faster communication to 9600 or 115200 baud. If a multi-amplifier set-up is installed with
Master/Slave communication, a smaller delay can be observed when using higher speeds.

g. Trigger Set-up
Trigger set-up sets the usage of the trigger output option. If e.g. an SDA2175 is connected
to drive a subwoofer from the Line out, the trigger can be activated and used for controlling
the power of the SDA2175.
h. Remote Control
Remote Control set-up makes it possible to activate or de-activate the remote control. This
is useful in set-ups with more than one TDA 2200 amplifier in the room. The master
amplifier then becomes the only one receiving signals from the remote, processes them
and controls the rest of the TDA 2200’s over the Lyngdorf RS232 link.
i. Display
The sub menus accessible in the Display menu are:
• Display Timeout
• Display Brightness
Display timeout set-up is used for enabling/disabling the 10 sec. display fade-out feature. If
enabled the Main Display reading will fade out after 10 sec of inactivity from the remote
control or front panel buttons.
Display brightness is used to control the brightness of the display. The brightness can be
set to 25%, 50%, 75% and 100%.

j. Volume
The sub menus accessible in the Volume menu are:
• Def. Volume
• Max. Volume
The Default Volume setting controls the default volume at start-up and can be set from 0 to
99 dB. However, a setting over 88 is not recommended as this corresponds to max output
with full scale digital input.
The Maximum Volume setting is a safety precaution used for limiting the maximum volume
which can be achieved by spinning the wheel or increasing volume via the remote. This
can be set to avoid excessively loud sound pressure levels and/or to protect your
loudspeakers against overload.
19
Download from Www.Somanuals.com. All Manuals Search And Download.
k. Advanced set-up
The sub menus accessible in the Display menu are:
• Master/Slave
• Line Out Volume
• Software version
• Default
As default a TDA 2200 is set as a Slave. The Master setting should be used if you are
using two TDA 2200, e.g. for bi-amping or if using one to drive the main loudspeakers and
one to drive the (sub)woofer(s). When set as a Master the first TDA will control the second
TDA (the Slave) e.g. when adjusting the volume control and when switching on and off.
The Line Out level can be set as Full Scale (fixed) or regulated.
Fixed means there’s a constant full scale output – also often referred to as “tape out” since
this is most often used for this purpose.
Regulated means that the output level will follow the level of the volume control. This
setting is chosen if you have, for instance, a power amplifier or an active subwoofer
connected. If Full Scale is used in this scenario you will constantly have full output – with
huge potential for overloading and damaging the connected power amplifier and/or
loudspeakers.
The Software version menu is used to check the current software version of your TDA2200
and the RoomPerfect™ module as well as the RoomPerfect™ serial number.
The Default setting is used to restore all settings in the TDA2200 to the factory settings.
If you return to the factory settings all your personal settings will be erased.

9. RoomPerfect™
The actual performance of a loudspeaker is known to be highly dependent on the
acoustics of your listening room and your listening and loudspeaker positions. Extensive
measurements in different rooms with high-end systems have shown that peaks and dips
between +10 and -20 dB in the frequency response are more often the rule than the
exception! This makes the room the weakest link in the audio chain, a weakness that we
have made our ambition to strengthen.
Our goal is not to make every audio system sound the same… far from it. Our goal is to
preserve the tonal balance of your loudspeakers and match them to your room by
compensating for your room’s influence. And therein lies a great challenge, to create a
generic room correction system that would maintain the tonality of your system and only
compensate for problems that could be solved. Nevertheless, it’s a challenge that has
been met in the Lyngdorf Audio-developed and patented RoomPerfect™ system.
The main task of RoomPerfect™ is to learn the 3-dimensional acoustical properties of a
room, by combining room measurements with measurements at the listening positions
(Focus). The 3-dimensional acoustical properties are obtained through an easy-to-use
guided set-up. When the guided set-up is completed, the acoustical properties are used
intelligently to shape the sound that is played, resulting in the Global and Focus 1 room
correction filters, which are calculated at the end of the guided set-up.
The following sections describe the guided set-up, the advanced menu, the daily use and
troubleshooting of RoomPerfect™.

a. The Guided Set-up – a Quick Guide
The RoomPerfect™ menu is found under the TDA 2200 main menu. If you have just
turned on your TDA 2200, press MENU to enter the TDA 2200 main menu.
Thereafter press enter to enter the RoomPerfect™ menu.
When you enter the RoomPerfect™ Main Menu for the first time, only the Guided set-up
is available. Press enter to initiate the guided set-up.
The main steps in the guided set-up procedure are:
1. Setting the measurement volume level
2. Taking one Focus (listening position) measurement
3. Taking at least three room position measurements
4. Adding more room measurements in the guided set-up (optional)
5. Finally, automatic calculation of Focus and Global filters
If you wish to leave the guided set-up at any time during the set-up, simply press the
MENU button and the following message appears.
Choose Yes to exit the guided set-up without saving any data, or choose No to cancel and
continue with the guided set-up.

b. Setting the measurement volume level
The measurement volume – also called the calibration volume – is a recommended
maximum volume. It is important that you always judge whether the measurement volume
is too loud. The calibration volume should not be so loud that it causes:-
1. uncomfortably loud sounds that are inconvenient to you and your environment, or
2. damage to your loudspeakers.
Connect the microphone to the microphone input found on the right side of the back panel.
Thereafter, place the microphone, using the microphone stand, in an appropriate
focus/listening position. This location should be at your main listening position, typically
more or less centered between the loudspeakers.
Make sure that the height and the orientation of the microphone corresponds to your
typical listening height and direction as illustrated in figure 3.
Fig 3: Measurement of main listening position
When the microphone has been correctly connected and placed in the focus position, you
are ready to set the calibration volume. The calibration signal is a combination of the high
and low frequency measuring signals and is only presented in your left loudspeaker. The
signals sound very artificial and disharmonic due to the fact that they are made up of pure
tones at different frequencies. Press enter to confirm and to commence the calibration
process.

The test signal will start and shortly thereafter the TDA2200 will suggest an initial estimate
of the desired maximum calibration volume (in dB).
Please raise or lower the volume towards the desired maximum volume shown on the
display but ensure you avoid clipping, uncomfortably loud levels and damage to the
loudspeakers. Continue choosing Retry for a re-estimation of the desired maximum
calibration volume, until an appropriate calibration volume is reached. If you find the
suggested calibration volume too loud simply turn down the volume to an appropriate level
and choose Save current.
When the message below is displayed, the calibration volume has successfully been set
and saved.
• When performing the required measurements in the guided set-up, the
environments should reflect your normal listening situation.
• Do not block the line of sight between the microphone and the
loudspeakers.
• The calibration volume found by RoomPerfect™ is a recommended
maximum volume. Lower volumes can be used if you consider the
measuring signal too loud for you, your environment and loud-
speakers.
• The orientation and height of the microphone in the focus/listening
position should reflect your main listening situation.
• The measuring volume can be changed at any time between
measurements simply by adjusting the volume.
The next step is to perform the first measurement, which is a focus/listening position
measurement, with the microphone placed in the same position as for the calibration
procedure.

c. Focus Measurement
When the calibration is OK, press enter to start the measuring process and the following
message will be displayed. Each measurement comprises four steps: a low and a high
frequency measuring signal first in the left and then in the right channel. The length of
each measurement depends on a combination of the measurement volume, set in the
calibration process, and the background noise in your local environment. Typical
measuring times for the low and high frequency measuring signals are 25 and 5 seconds,
respectively. As mentioned, the measuring signals sound artificial and disharmonic due to
the fact that they are made up of pure tones at different frequencies. It is advised that you
do not to sit in the listening position during this measurement.
The measurement will stop prematurely if an error occurs during the measuring process. In
this case, the error message is displayed. Press enter to continue and the following is
displayed.
If the error needs correcting this should be done at this point (see RoomPerfect™
troubleshooting), thereafter press enter to retry the measurement. The measurement
procedure will start again.
A measurement has ended successfully when the last measuring signal stops and the
display shows a RoomKnowledge rating, as in the following.
Press enter to continue.
Do not sit in the listening position during focus measurements.

d. Room Measurements
The number of room positions needed depends on the value of RoomKnowledge, if it is
below 90% after the third measurement the guide automatically includes extra room
measurements until a RoomKnowledge of 90% or more has been achieved.
The remaining measurements are to be placed in random positions in the room with
random orientations of the microphone. Choosing these random or arbitrary positions and
orientations is easy. All you have to do is place the microphone at different positions in the
room and with different orientations. It is important to perform well spaced measurements
to get a covering image of the acoustical properties in the room, i.e. varying positions,
heights and orientations of the microphone.
For an optimal room correction it is very important that the measurements are:
1. performed more than 1 meter (approx. 3 feet) away from the loudspeakers,
2. not performed behind the loudspeaker, and
3. that there is at least 50 cm (approx. 1.5 feet) between each measurement.
These points are illustrated in figure 4.
Fig 4: Illustration of guidelines for room measurements
When a random measuring position and microphone orientation has been chosen press
enter. The measuring process will start and the display will show the following while
measuring.
The measurement will stop prematurely if an error occurs during the measuring process. In
this case, the error message is displayed. Press enter to continue.
26
Download from Www.Somanuals.com. All Manuals Search And Download.
If it is an error that needs correcting, then correct the error (see RoomPerfect™ trouble-
shooting) and proceed with the room position measurement by pressing enter. The
measurement has ended successfully when the last measuring signal stops and the
display shows the following.
This process is repeated at least three times and until the RoomKnowledge reaches 90%.
• For each room measurement the microphone should be randomly
placed in the room and have a random orientation
• Perform well-spaced measurements to allow the system to get an
accurate image of the acoustical properties in the room, i.e. varying
positions, heights and orientations of the microphone.
• For optimal room correction it is very important that the measurements
are: performed more than 1 meter (approx. 3 feet) away from the
loudspeakers, not performed behind the loudspeaker, and that there is
at least 50 cm (approx. 1.5 feet) between each measurement, see
figure 4.
e. Adding more room measurements
If you have performed 4 successful measurements and RoomKnowledge has reached
90%, then the following message is displayed.
At this point you can decide whether the acquired room measurements are sufficient or
whether you wish to add further room measurements to learn more about the room’s
acoustical information. Adding more room measurements results in a higher
RoomKnowledge, this in turn improves the room correction filters.
Choose Yes to add more room measurements. The room measuring process is now
repeated as described in the previous section. In short, place the microphone in a random
position with random orientation and press enter to commence the measurement.
Choose No when no additional measurements are required. The volume will now return to
default volume or lower, depending on the volume you have entered the guided set-up
with.
27
Download from Www.Somanuals.com. All Manuals Search And Download.
The above will be displayed when exiting a successfully completed guided set-up.
Choose No if you wish to exit the guided set-up without calculating any room correction
filters, without saving the performed measurements and without setting the calibration
volume.
Choose Yes to save the results of the guided set-up and calculate the focus and the global
room correction filters.
• You can, at any time, add more room measurements
• Adding room measurements increases the accuracy of the room
correction filters
f. Calculation of Focus 1 and Global Filters
When RoomPerfect™ calculates the filters the display shows the following.
The filter calculation process can be expected to take anywhere between 5 seconds and a
minute depending on the specific task.
When RoomPerfect™ has calculated the room correction filters, they are automatically
saved. The Focus filter is saved as setting 1 and Global is saved as setting 9 out of the
possible 9 filter settings.
You have now successfully completed a guided set-up and the RoomPerfect™ Advanced
Menu is now available.

10. RoomPerfect™ Advanced Menu
This section describes the options in the advanced menu. Here you can select position,
add new listening positions and room measurements, check the RoomKnowledge of your
current set-up, and check the RoomCorrection for the different filters.
a. Selected Position
In this menu it is possible to select a desired RoomPerfect™ filter, i.e. Global and the
Focus position(s). The current position is shown in the display and a new position can be
selected simply by pressing the left/right buttons.
b. Adding a New Focus Position
As mentioned, after the guided set-up it is possible to add 7 new listening/focus positions.
As previously described, place the microphone correctly in a new listening position and the
measurement process can commence. This could, for example, be in a lounge chair or a
position by a window with a good view.
29
Download from Www.Somanuals.com. All Manuals Search And Download.
The saved calibration volume from the guided set-up is used as a default when adding
extra focus/listening and room positions though, as mentioned, the volume can be
changed at any time between measurements to suit a particular situation.
After a successful measurement the following message is displayed. The value of
Roomknowledge can be different.
Press enter to continue.
Choose Yes to save the measurement or choose No to exit without saving the current
measurement.
Choose between focus/listening position presets 2 - 8 and press enter. If you wish to
overwrite an existing focus filter (2 to 8 can be overwritten) or you are trying to save a new
filter on an existing preset then the following will be displayed.
When the preset number has been chosen, the volume turns down to default or lower and
the new focus filter is calculated and saved.

c. Adding a New Room Position
It is always possible to add more room measurements, which can increase
RoomKnowledge and thereby fine tune all the room correction filters.
Press enter to start a new room measurement.
As previously described, place the microphone correctly in a random room position and
the measurement can commence.
The saved calibration volume from the guided set-up is used as default when adding extra
focus/listening and room positions, though as mentioned, the volume can be changed at
any time between measurements to suit a particular measurement situation.
After a successful room measurement the RoomKnowledge is re-calculated and displayed.
Press enter to continue.
Choose Yes to add another room measurement or choose No to stop adding more room
measurements. If No is chosen the volume is returned to the default or lower.
31
Download from Www.Somanuals.com. All Manuals Search And Download.
Choose Yes to save the performed room measurement and No to exit without saving any
of the performed measurements.
Adding one or more room measurements leads to a re-calculation of all filters (i.e. Global
and all Focus filters) due to the fact that more of room’s acoustic properties have been
learned, something that affects all filters.
d. RoomKnowledge Index
Here the current RoomKnowledge index is displayed
Press enter to check the RoomKnowledge index.
The RoomKnowledge index is a parameter that tells how much of the room’s acoustical
properties have been learned. A high RoomKnowledge (≥90%) means that most of the
room’s acoustical properties have been learned. The more room measurements you add,
the higher the RoomKnowledge will become. The more that the acoustical properties of
the room are learned, the greater the accuracy of the room correction.
e. RoomCorrection Index
Here the RoomCorrection index for each filter can be viewed.
Press enter to check the RoomCorrection index.
The RoomCorrection index is a measure of how much processing is being employed in the
room correction filters. To some extent the RoomCorrection index reflects how audible the
correction is. However, the same amount of processing can sound very different due to
32
Download from Www.Somanuals.com. All Manuals Search And Download.
placement in frequency of the processing. For low values (below 10%) of the room
correction index, only subtle correction is needed to the original sound in the room. With
high room correction index values more extensive processing is employed.
The RoomCorrection index for a specific RoomPerfect™ filter shown above can be viewed
by pressing the numerical button of the corresponding filter.
11. Daily Use of RoomPerfect™
Once the guided set-up has been successfully completed you now have the option to
listen to music through two listening settings; Focus 1 and Global room correction filters.
The RoomPerfect™ filters are stored on the numerical buttons from 1 to 9 on the remote
control. To change from one filter to the other you simply press the numerical button
corresponding to the desired filter. This can also be selected in ‘Select Position’ under the
RoomPerfect™ advanced menu when using the front panel interface.
Global is stored on numerical button 9 and the Focus 1 is stored on numerical button 1. As
mentioned, you can have more than one Focus/listening position (8 in all). The additional
focus/listening positions can be stored on numerical buttons from 2 to 8. To bypass the
room correction filters, press numerical button 0.
a. Global Listening
The Global filter improves the sound quality across the whole room. When you are
listening to music in a room but are not sat in any particular listening position, the global
filter gives the best result.
b. Focus Listening
The Focus filter improves the sound quality at a listening position by exploiting the 3-
dimensional acoustic properties gained through the room measurements. This makes the
Focus filter the best solution for optimal sound quality at a specific listening position.

12. RoomPerfect™ Troubleshooting
a. No microphone connected
This is displayed when no microphone is connected to the TDA2200.
Solution:
Connect the microphone on the right-hand side of the back panel.
b. Fault - No signal
The error message shown above is displayed when the incoming signal is classified as
pure noise.
The Fault No signal message is displayed if the measuring signal is too low compared
with the noise from the local environment. This could be due to there being too much noise
in your measuring environment.
Solution:
Raise the measuring signal volume before continuing with the measurement.
The above error message is also displayed when the loudspeakers are not connected
and/or Mute is activated.
Solution:
Connect your loudspeakers and/or de-activate Mute.
34
Download from Www.Somanuals.com. All Manuals Search And Download.
c. Fault - Signal clipping
The above error message is displayed when the incoming signal is classified as too loud
resulting in clipping (distortion).
An overly loud measuring signal results in this error message.
Solution:
Lower the measuring signal volume before continuing with the measurement.
A loud noise from the local environment that has corrupted the measurement results in this
error message.
Solution:
Repeat the measurement with no changes; however refrain from making excessive
noise when measuring.
Useful hint: You can exit a commenced measurement by clapping close to the
microphone. This results in the above error message.
d. Fault - Low signal
The above error message is displayed when the measurement has taken more than 5
minutes for the low frequency signal or 2 minutes for the high frequency signal. This
happens most often when using a low measuring signal compared to the background
noise of your environment, something that results in prolonged measuring times.
Solution:
Raise the measuring signal volume before continuing with the measurement, or
reduce the noisy elements in your environment.
