Operating Voltage
The RP-1 can be switched between 115V and 230V mains voltage.
In 115V mode the RP-1 requires a mains voltage of 100V-120V at 50-60Hz.
In 230V mode the RP-1 requires a mains voltage of 220V-240V at 50-60Hz.
The mains voltage setting for your RP-1 can be changed on the rear selector.
Make sure the rear selector is in the correct position and connect the power input
only to the appropiate AC source. The warranty will not cover any damage caused
by connecting to the wrong type of AC mains.
The RP-1 has three power modes:
1. OFF
No circuitry is powered. Please note that some parts of the mains entry section still carry live mains.
2. STANDBY
The microprocessor is active..
3. ON
All circuits active.
Unpacking the RP-1
Carefully remove the unit and accessory kit from the carton, visually check for shipping damage.
Contact both the shipper and your Lyngdorf Audio representative immediately if the unit bears any sign
of damage from mishandeling. All Lyngdorf Audio equipment is carefully inspected before leaving our
factory.
Keep shipping carton and packing material for future use or in the unlikely event that
the unit needs servicing. If this unit is shipped without the original packaging, dam-
age could occur and void the warranty.
Serial Number Registration
Please record the serial number of your RP-1 here for future reference. The serial number is printed on
the label on the rear panel. You will need this serial number, should you ever require service for your
RP-1.

Introduction
Congratulations on the purchase of your Lyngdorf Audio RP-1 with RoomPerfect™.
This ‘Black Box’ expands your existing music system with the most advanced room correction system
on the market. It is implemented in such a way that you will always achieve the perfect result. No com-
puter needed, no acoustic knowledge needed, no user input needed. We leave nothing to chance in the
fully automated calibration process.
However, for the advanced user there are plenty of challenges since the RP-1 is also a complete ‘Control
Centre’ that allows you to build advanced multi-way passive or active speaker systems. This is possible
due to the very powerful built-in DSP ‘engine’ which facilitates signal routing, creation of active cross-
overs, delay settings etc.
In fact we believe the RP-1 to be a true ‘Black Box’ in the way that it sets new standards for what’s pos-
sible to improve sonically in a music system.

Connecting the RP-1
The photos used are only meant as visual aids to show the versatility of the RP-1,
Lyngdorf Audio doesn’t necessarily carry all other products with the described speci-
fications in the product assortment.
Connecting to sources and amplifiers
The RP-1 is very simple to hook up. There are three basic ways to connect the RP-1 to your system.
1. Connect all sources to your preamplifier and connect it to the RP-1 input.
Then connect the RP-1 output signal to a poweramplifier.

Connect the output of the ‘tape 2’ loop / ‘Pre out’ to the input of the RP-1.
Then connect the output of the RP-1 to the input of the ‘tape 2’ loop / ‘Pre in’.
Using this configuration enables you to use multiple audio sources without switching source and/or
cables, since the ‘tape 2’ loop ‘Pre in/out’ is always active and not depending on other used inputs

Introduction to RoomPerfect™
Once the guided set-up has been successfully completed you have the option to listen to music through
two listening settings; Focus and Global room correction filters. To toggle between the two filters and
‘Bypass’ you simply press the Up/Down buttons on the front panel or remote control.They can also be
selected directly with the numerical buttons on the remote, 0 for bypass, 1 for Focus or 9 for Global.
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.
Focus Listening
The Focus filter improves the sound quality at a listening position by exploiting the 3-dimensional acous-
tic properties gained through the room measurements. This makes the Focus filter the best solution for
optimal sound quality at a specific listening position.
Voicing
When using RoomPerfect™ you will experience a much more precise and detailed sound reproduction
– which could also be described as more analytical.
The Voicing setting is an EQ filter that can be used to gently amplify or attenuate certain frequencies ac-
cording to your personal preferences and/or to compensate if a given recording sounds too ‘bright’ or too
‘dark’. The standard voicing settings, and their numerical value on the remote control, are:
•
Neutral (0), Music 1 (1), Music 2 (2), Relaxed (3), Open (4), Open Air (5), Soft (6).
The frequency curves of the different voicing settings can be viewed in the appendix. Neutral is a bypass
setting.
You can toggle between neutral and the available voicings by pressing the Left/Right buttons on the re-
mote or front panel. The can also be selected directly by pressing “info” followed by the voicing number
on the remote control.

Setting the Measurement Volume Level
When setting the measurement volume level, it is important that you always judge whether the calibra-
tion volume is too loud. The calibration volume should not be so loud that it causes:
•
•
uncomfortably loud sounds that are inconvenient to you or your environment, or
damage to your loudspeakers.
When the message ‘Connect and place mic. in focus pos.’ appears, connect the microphone to the mi-
crophone input found on 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 and do not block the line of sight between the microphone and the
loudspeakers.
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 measur-
ing signals and is only presented in your left loudspeaker. The measuring signals sound very artificial and
disharmonic due to the fact that they are composed of pure tones at different frequencies.
Press Enter to confirm and to commence the calibration process.
If the RP-1 is connected before the volume control of your amplifier e.g. when using
Option 2 or a ‘tape 2’ loop as described in Option 3 in the “Connecting the RP-1”
chapter, be aware that the volume control of your amplifier is set at an appropriate
level when making the RoomPerfect calibration.
The volume control should be set at 0dB, which typically is in the “12 o´ clock” po-
sition. This setting must be used again if you wish to add additional RoomPerfect
measurements later.
The test signal will start and shortly thereafter the RP-1 will suggest an initial estimate of the desired
maximum calibration volume, displayed as ‘Adjust level: XX up/down - Retry/Save Current’
Please raise or lower the volume by pressing the Up/Down buttons on the RP-1 front panel or remote
control towards the desired number of steps shown on the display but ensure you avoid clipping, uncom-
fortably 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 ‘Calibration ok. Press Enter to continue’ is displayed, the calibration volume has suc-
cessfully been set and saved.
Focus Measurement
When the calibration is OK, press Enter to start the measuring process and ‘Measuring Focus position
…’ 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.
You can exit a commenced measurement by pressing the “Menu” button.
Do not sit in the listening position during focus measurements.
The measurement will stop prematurely if an error occurs during the measuring process. In this case,
an error message is displayed. Press Enter to continue and ‘Retry focus measurement – press Enter’ 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 ‘RoomKnowledge XX% - Measurement ok’. Press Enter to continue.
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 RoomKnowl-
edge of 90% or more has been achieved.
The remaining measurements are to be placed in random positions in the room with random orienta-
tions 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/1.5 ft between each measurement.

When a random measuring position and microphone orientation has been chosen press Enter. The measur-
ing process will start and the display will show ‘Measuring room position 1’.
The measurement will stop prematurely if an error occurs during the measuring process. In this case, the
error message ‘Retry room measurement – press Enter’ is displayed. Press Enter to continue.
If it is an error that needs correcting, then correct the error (see RoomPerfect™ trouble-shooting) and pro-
ceed with the room position measurement by pressing Enter. The measurement has ended successfully
when the last measuring signal stops and the display shows ‘RoomKnowledge XX% - Measurement ok’.
This process is repeated at least three times and until the RoomKnowledge reaches 90%.
Adding more Room Measurements
If you have performed successful measurements and RoomKnowledge has reached 90%, the message
‘Add more room meas.? Yes/No’ is displayed.
At this point, or any time later, you can decide whether the acquired room measurements are sufficient or
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 continued as
described in the previous section.
•
Choose No when no additional measurements are required. The RP-1 will return to full scale output.
The message ‘Save guided measurement - Yes/No’ will be displayed when exiting a successfully completed
guided set-up.
•
Choose Yes to save the results of the guided set-up and calculate the focus and the global room
correction filters.
•
Choose No if you wish to exit the guided set-up without calculating any room correction filters, without
saving the performed measurement.

Calculation of Focus and Global Filters
When RoomPerfect™ calculates the filters the display shows the following, ‘Calculating filters - Please
wait’.
The filter calculation process can be expected to take anywhere between 5 seconds and a minute de-
pending on the specific task.
When RoomPerfect™ has calculated the room correction filters, they are automatically saved.
You have now successfully completed a guided set-up and the RoomPerfect™ Advanced Menu is now
available.

If the RP-1 is connected before the volume control of your amplifier e.g. when using
Option 2 or a ‘tape 2’ loop as described in Option 3 in the “Connecting the RP-1”
chapter, be aware that the volume control of your amplifier is set at the same level
as when making the initial RoomPerfect calibration.
If you do not remember this setting, you will need to perform a new guided setup.
Change Focus Position.
If you want to replace your current listening position (Focus filter), place the microphone correctly in the
new listening position and the measurement process can commence as described in the ‘Guided Setup’
chapter.
After a successful measurement the message ‘RoomKnowledge XX% - Measurement ok’ is displayed.
Press Enter to continue.
The message ‘Replace old focus measurement?’ will appear.

It is always possible to add more room measurements, which can increase RoomKnowledge and there-
by fine tune both room correction filters (Focus and Global).
Press Enter to start a new room measurement.
First the volume must be calibrated, as described in the ‘Guided Setup’ chapter. Then place the micro-
phone in a random room position and the measurement can commence.
The volume can be changed at any time between measurements to suit a particular measurement situ-
ation.
After a successful room measurement the RoomKnowledge is re-calculated and displayed as ‘Room-
Knowledge XX% - Measurement X ok’. Press Enter to continue.

‘Add more room meas.? Yes/No’ will show in the display:
•
•
choose Yes to add another room measurement or,
choose No to stop adding more room measurements. If No is chosen the RP-1 is will return to full
scale output.
‘Save room measurement(s)? Yes/No’ will hereafter be shown.
•
•
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 both filters (i.e. Global and Focus
filters) due to the fact that more of room’s acoustic properties have been learned, something that affects
these filters.
When adding room measurements, make sure the system volume is the same for
all measurements. Whether adding more room measurements now or later.
If you can´t remember the volume setting, we recommend to delete the filter and
start over.
RoomKnowledge
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.
RoomCorrection
The RoomCorrection index is a measure of how much processing is being employed in the room correc-
tion filter. To some extent the RoomCorrection index reflects how audible the correction is. However, the
same amount of processing can sound very different due to 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.

Input Sensitivity
Input Sensitivity
The Input Sensitivity setting enables you to match the line level output of your pre-amplifier to the input
sensitivity of the Lyngdorf Audio RP-1. The normal settings are:
•
Select ‘High’ for input levels <= 2.2Vrms and the output/input levels of your pre- and power
amplifier will match.
•
•
Select ‘Low’ for input levels > 2.2V RMS.
Select ‘High + Gain’ for input levels <=2.2Vrms and add an extra +6dB gain to increase the output
level of your pre-amplifier to match your power amplifier. This setting is only to be used in
special cases where the output level from your pre-amplifier is too low to obtain full output
from your power amplifier. In ‘High’ and ‘Low’ sensitivity the RP-1 has unity (0dB) gain.
Selecting the correct setting will prevent clipping/distortion and obtain full scale out-
put from your pre-amplifier.

Mono lowpass filter
A highpass and a lowpass filter can be applied to the Main and Line outputs when you want to connect
an additional amplifier or subwoofer along with your main amplifier.
A Mono setting is also available for the Line output, this is used when connecting a single subwoofer to
the Line output.
If no filter is selected the full frequency range will be directed to the Main and Line Out terminals. If a
filter is selected the frequencies above or below the selected crossover frequency will be directed to the
analog Main or Line Out terminals.
When a highpass or lowpass filter has been chosen, the Crossover Frequency and Filter Type menus are
enabled.

27
Crossover Frequency
Crossover freq.
Crossover Frequency is only available when Routing has been setup.
The Crossover Frequency can be selected anywhere between 40 – 9999Hz.
It is very difficult to give exact guidelines to setting a suitable crossover frequency, filter type and order
since this depends on the exact drivers and configurations. Therefore, the following recommendations
should be seen as a good starting point only.
In general, the recommended crossover frequency between (sub)woofers and main speakers is be-
tween 200 - 400 Hz.
By using a high crossover frequency, the rear wall quarter wavelength reflection is removed from the
main speakers.
If a Lyngdorf Audio boundary woofer is used in a 2+2 set-up, a crossover frequency of 400 is recom-
mended due to the high bandwidth of the boundary woofer.
For conventional active subwoofers with built in low pass filter the recommended crossover frequency
is the upper low-pass frequency of the subwoofer.
If at all possible, the low pass filter in the subwoofer should be bypassed. Due to the quarter wave
reflection from the rear wall corresponding to the depth of the subwoofer cabinet we recommend an
crossover point at approximately 200 Hz. You might experiment with turning the subwoofer so the driver
faces the wall in a distance of 5 to 10 cm. This will increase the bandwidth of the subwoofer.
However, due to the limited bandwidth (frequency response) of most conventional subwoofers you
might find it necessary to choose a lower crossover frequency.
When ‘building’ active speaker systems it is recommended to use the original crossover point(s) used
by the manufacturer. Due to the short wavelengths of the mid/high frequencies it is essential that both
crossover frequency, filter type and order as well as delay is set correctly. Therefore, creating filters for
active speakers is an iterative process that requires several critical listening sessions in order to achieve
seamless integration of the different speaker drivers.
Filter Type
Filter Type
Filter Type is only available when Routing has been setup.
It is possible to choose from two different Filter Types in this menu.
LiRi: (Linkwitz Riley) 2, 4 or 8 order.
Butw: (Butterworth) 1, 2 or 4 order.
In a 2+2 set-up (main speakers + Lyngdorf Audio boundary woofers) we recommend using a fourth order
Linkwitz Riley filter.
In set-ups using conventional active subwoofers – again due to limited bandwidth – we recommend us-
ing a second order butterworth filter.
In active speaker systems it is recommended starting with a fourth order Linkwitz Riley filter.

Delay
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 sub-
woofer, or a Lyngdorf Audio 2+2 system, you need to 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 as well as 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 posi-
tion and enter these values in the menu. The necessary delays are then automatically calculated and
applied to each channel.
1 centimeter = 0.3937 in
The fault message ‘Values for delay exceed limits’ is displayed when the difference
between the distance from the speakers closest to, and the speakers furthest from,
the listening position is too big. The biggest difference allowed is 340 cm / 134 in.
If the fault message appears, you can use the following 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 channel loudspeakers resulting in a more
compact loudspeaker set-up.
•
Arrange your loudspeaker set-up and/or your listening position in a more symmetrical set-up.

Troubleshooting
RoomPerfect™
No microphone connected
The error message ‘No microphone connected’ is displayed when no microphone is connected to the
RP-1.
Solution:
• Connect the microphone on the back panel.
No signal
1. The error message ‘Fault – No signal’ is displayed when the incoming signal is classified as
pure noise. This happens when the RP-1´s measuring signal is too low compared with the noise
from the local environment.
2. The volume setting of your amplifier and/or RP-1 measuring volume is to low.
3. The above error message is also displayed when the loudspeakers are not connected.
Solution:
• Reduce the noise in your measuring environment.
• Raise the volume setting of your amplifier and/or RP-1 measuring volume before continuing with the
measurement.
• Connect your loudspeakers.
Low signal
The error message ‘Fault – Low signal’ 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 when
the system calibration volume is low compared to the background noise of your environment, some-
thing that results in prolonged measuring times.
Solution:
• Raise the RP-1´s measuring volume or the volume setting of your amplifier before continuing with
the measurement, or reduce the noisy elements in your environment.
Signal clipping
1. The error message ‘Fault – Signal clipping’ is displayed when the incoming signal is
classified as too loud resulting in clipping (distortion).
2. A loud noise from the local environment that has corrupted the measurement results in this
error message.
Solution:
• Lower the measuring signal volume before continuing with the measurement.
• Repeat the measurement with no changes; however refrain from making excessive noise
when measuring.
