Introduction  
In choosing the 501/501V Control Unit you have acquired a component  
that combines major advances in audio and engineering design. The 501  
Control Unit is a full function preamplifier for use with high performance  
analogue sources. It provides six audio inputs, each of which can be  
individually adjusted for sensitivity, and identified on the four-character  
alpha-numeric display. A very high quality MC or MM phono stage is  
available as an option for the dedicated LP input.  
In addition, the 501V Control Unit provides video switching for up to eight  
video inputs.  
This guide is designed to enable you to obtain the best possible results  
from the unit, and it includes information about customising the unit to  
your own requirements.  
If you have just purchased the 501/501V Control Unit you should first turn  
to the chapter Setting up the Control Unit, page 33, which explains how to  
unpack and install the control unit correctly.  
The Meridian 500 Series  
The Meridian 500 Series is a unique system of digital, analogue,  
and video components designed to meet the demand for  
absolute quality, ease of use, and lasting value.  
500 Series communications  
The Meridian 500 Series includes a sophisticated  
communications link, to ensure that any configuration of units  
will work together as a fully integrated system.  
The flexibility of the Meridian 500 Series is such that you can  
assemble a system as simple or as complex as you need,  
perfectly suited to your musical and environmental requirements,  
and with the ability to add to it or change it at a later date should  
your requirements change. The 500 Series is also compatible  
with the existing Meridian 200 Series and 600 Series  
components.  
The 500 Series communications system allows you to control  
any combination of units using a single handset, and ensures  
that your commands from the handset are interpreted  
unambiguously. Any unit can be designated as the controller for  
the system, allowing you to position the other units out of range  
from the handset beam if desired. It also allows all the units to  
be switched off from the front panel of any unit in the system.  
Each Meridian 500 Series component is housed in a matching  
slim line case. Front panel controls provide access to the most  
important functions, and the full range of functions is available  
from the Meridian System Handset using a simple and intuitive  
control interface.  
Professional features  
The 500 Series also includes features for professional users,  
including RS232 computer control (501, 562, and DSP5000), and  
balanced outputs (563).  
The following pages give examples of four suggested  
configurations to illustrate the flexibility of the Meridian 500  
Series.

Using the Video  
Features (501V only)  
This chapter explains how to use the video features in the 501V Control  
Unit to select the video source you want to watch, or to choose which  
video source to copy to a video recorder.  
Note that these instructions do not apply to the 501 Control Unit, which  
does not include the video option.  
Selecting a video source  
With the 501V Control Unit you select the video source you want  
to watch in exactly the same way as selecting an audio source.  
To select a source  
Press Source (front panel) until the display shows the source  
you require, or press the appropriate source key on the  
remote control.  
On the 501V Control Unit each source can be associated with  
both audio input, and a video input.  
For example, by default the TV source selects audio input A5 (for  
TV sound), and video input V5 (for the TV picture).  
For example, if you select the  
TV65  
TV input the display will show:  
Last valid option  
By default, the following six video sources are available:  
The audio or video input for a source can be defined as LV (Last

Customising the Control  
Unit  
This chapter explains how to customise the 501/501V Control Unit to your  
preferred configuration.  
The simplest way of configuring the control unit is to choose one of the  
standard settings, which are designed to cater for the six most common  
configurations of sources and inputs.  
Alternatively, you can configure each source individually to suit the other  
equipment in your system. You can choose the label used for each source,  
and balance the input sensitivities so that the sound level remains the  
same when you switch between sources.  
Finally, the 501/501V Control Unit provides several settings that you can  
alter to optimise the way in which it works with the other equipment in  
your system.  
Press

Choosing standard settings  
The 501/501V Control Unit provides six alternative standard  
settings, called Types, which configure all aspects of the control  
unit into the six most commonly needed configurations.  
To select a standard setting  
Switch off any power amplifiers that are connected to the  
control unit.  
Choosing one of the six standard settings overrides any other  
configuration you may have performed, and so can be used to  
reset the configuration of the control unit.  
Turn off the control unit, using the power switch on the back  
panel.  
Turn on the power again while holding down the Off key on  
By default, the control unit is supplied set to Type 1.  
the front panel.  
If you have a system containing only Meridian 500 Series units  
then you should choose one of Types 5, 1, 4, or 3. These give  
progressively larger numbers of inputs, as shown in the tables  
on page 21 (501) or page 22 (501V).  
Type  
The display will show:  
Ty 1  
It will then show:  
If your system includes any Meridian 600 or 200 Series units you  
should choose Type 2 or Type 6. For more information see To  
connect to Meridian 600 or 200 Series equipment, page 38.  
For example, to select Type 3  
the display shows:  
Ty 3  
Turn off the control unit using the power switch on the back  
panel.  
Turn on again to use the standard settings you have selected.

To change the video input for a  
source  
When you select the source you have configured you will get  
radio sound and a TV picture, as required for simultaneous  
broadcasts.  
Display the source you want to configure, together with the  
current video input, as described in the previous sections.  
To set up a system with two CD  
players  
For example, to configure  
CDLV  
the CD video input choose:  
Configure the source you are going to use for the first CD  
player.  
Press V or A to choose the video input.  
For example: Source CD, Label C1, Audio input A2, Comms  
type 1C, Address 1A.  
For example, if you always want the  
CDV5  
TV picture when you select CD set it to:  
Configure the source you are going to use for a second CD  
To set up a source for simultaneous  
broadcasts  
player, with a different address.  
For example: Source CDR, Label C2. Audio input A3, Comms  
type 1C, Address 2A.  
Choose a source you are not already using.  
Assign a suitable label to the source; SB is suggested.  
Configure the audio input to A3 (Radio).  
Configure the video input to V5 (TV).  
The remote control will now automatically control whichever of  
the CD players you have selected with the CD or CDR source  
keys.

Programming levels  
The 501/501V Control Unit allows you to program the level of  
each source independently, to suit your other equipment, so that  
when you switch between sources the volume stays the same.  
To balance input levels  
Switch off any power amplifiers that are connected to the  
control unit.  
When you are programming levels the control unit operates as a  
preamplifier with a fixed volume setting equivalent to 65. This  
level is chosen to be comfortably loud on average sources. You  
can switch between sources and adjust the relevant input levels  
to achieve the setting you want.  
Turn off the control unit, using the power switch on the back  
panel.  
Turn on the power again while holding down the Mute key on  
the front panel.  
You can increase the sensitivity of any source by up to 15 steps  
of 1dB. The loudest source, usually CD, should therefore be  
chosen as the reference.

Use the A and V keys to change the sensitivity.  
If you know the output level of your sources you can probably  
set the gains by calculation. The following table shows the  
correspondence between the gain and sensitivity on the  
standard audio inputs and on the LP inputs:

keypad  
Remove the mains connector, and pull out the drawer next to  
the power input to access the fuses.  
Use a slightly damp cloth.  
Before replacing a blown fuse, if possible ascertain the cause of  
the failure.  
Ensure that no water is allowed to get inside the case, and do  
not reconnect the power until you are certain that the control  
unit is completely dry.  
The fuse drawer includes a spare fuse. This should be replaced  
by one of the same rating.  
To clean the audio and video  
connections  
The audio and video sockets on the rear of the control unit are  
gold-plated and need no cleaning if gold-plated phono plugs are  
used. Otherwise, it is recommended that you unplug and

tampered with or modified in any way without the written  
authorisation of Meridian Audio Limited. Note that connecting  
anything other than the correct network lead to the COMMS  
sockets may cause damage to the 501/501V Control Unit which  
will not be covered by this guarantee. Attempted servicing by
