The Z-2M & Z-2MR Dual Zone Mixers

The Z-2M & Z2MR are high quality zone mixers that
are easy to operate while extensive enough in their
installer features. With many years of experience in
the manufacturing of zoning systems for leisure
applications at Citronic we know how important it is
to make our devices operator friendly. The Z-2M &
Z2MR are no exception.

The simple user controls belie the
extensive installer options that are either mounted
on the rear panel or hidden below the top cover,
which cannot be accessed while the mixer is
mounted on in a rack. All the equalisation,
sensitivity and priority controls are installer
accessible only. Full details of which are explained
in the body of this manual.

There are 5 inputs in total; Microphone,
three line and a priority. The priority input can be
used as a fourth line input by engaging it on the
front panel while the other inputs are switched off.
All of these inputs have their own gain control
mounted on the rear panel.

Both of the output zones are balanced
stereo low impedance. There is also a mono
selector switch for each of these outputs.

The rear panel is completed by provision
for the connection of expansion modules to
increase the number of zones (up to six), access
for the remote control option and an IEC AC power
connector.

The user controls for each output zone are
simple. There is a rotary selector switch to select
the input, a microphone level control, a music level
control and a button to activate the priority music
input.

The music channels have an Eq auto
loudness control that maintains the equalisation
settings you set across a wide variation in volume
settings. Normally you would need to increase the
bass in a music signal as you decrease the
volume to maintain the apparent listening balance
between high and low frequencies. In this system
it is not necessary. Simply set up the Eq you wish
at the highest volume setting and the system will
re-balance it for lower volumes.

WARNING: In order to obtain the best service from the unit we STRONGLY recommend that you read this

manual before you apply any power.

Front Panel Controls Z-2M

1) AC Power Switch

Switches on or off the AC power to the unit and any expander units that may be plugged into it.

2) Power LED

Indicates green when the power switch is on.

3) Zone 1 (or 2) Input Selector Switch

In position off, (as illustrated) all the music inputs are defeated, the possible exception is the priority input, which is
explained below.
In position Line 1, 2 or 3 the zone output will carry the selected source. The inputs can be labelled to indicate the source.

4) Music Priority Inputs

This switch selects the music source connected to the priority input, and the LED will illuminate to indicate this. The priority
input sensitivity and release times must be set up at the time of installation for this function to operate correctly.
When this function is selected and a signal is present on the input, any music playing on input selected by the selector
switch will be overridden and replaced by the priority input signal. If no other inputs are selected, i.e. the selector switch is
in the “off” position the priority input acts as another ordinary line input. See the section in installer set up on sensitivity
control as this must be set up for the system to work properly.

5) Input Zone Labelling

Spaces are provided to label the zone inputs for the users information.

6) Music Level

This control alters the volume of the music in its associated output zone. It is an overall level control for the zone treating
all inputs the same. To cater for different input levels refer to the rear panel level controls detailed in section (12)

7) Microphone Level

This controls the microphone level in the appropriate zone. This control when set at minimum, will defeat the override
depth to the music signal.

Installation Notes:

The Z-2M & Z-2MR are quick and easy to install using conventional connectors. It’s a good idea to double check all

your interconnections as the Z-2M & Z-2MR will only perform to their optimum if the inputs and outputs are properly made.
Always use good quality connectors such as Neutrik® it’s a small investment that can save your time and money.

Connecting Up

8) Microphone Input

The microphone input is balanced. If you wish to use an unbalanced microphone, short pin 3 to pin 1 (ground) and
connect the signal input pin 2. This microphone has first priority in the system and will override the music signals. Full
details of the override control and EQ settings are detailed in the next section (installer Settings).

9) Microphone Gain

This control alters the input gain of the microphone circuit in order to match the output from the microphone. Adjust this
control so that the microphone level control on the front of the Z-2M provides the required volume range. Reduce this
control if distortion occurs.

10) Alarm Detector

This feature allows you to interface this audio system with the alarm system of the venue. All that is required to detect an
alarm condition is that the two terminals are shorted. The associated push button allows you to choose whether the music
signals are reduced by 25dB or 40dB in the alarm condition.

Note: The microphone input is unaffected by this attenuation so that announcements can still be made.
Note: The terminal you can see unplugs from the unit so that the wiring can be completed remotely as access to the back

of the rack is sometimes awkward. These terminals need to be shorted together by an external relay in the alarm system.

11) Zone Expansion Socket

It is possible to add zones to the system by the addition of Citronic’s Z-2X or Z-4X expanders. This socket makes
interconnection simple and is for the ribbon cable supplied with the expanders.

12) Input Gain Control

Because the inputs of various equipment like CD players and tape decks vary so much the Z-2M & Z-2MR are fitted with
input gain control so that you can match the varying inputs to give the same volume level control range from the music
level control on the front panel or Remote.

13) Input Sockets

Two Phono (RCA Phono jack) connectors for your music input device. This device can be virtually any source, e.g. CD
player, tape deck or satellite feed. If your music source is mono connect to the left and the right input using a proprietary
Phono splitter cable or connector.
