Introduction
The modular construction of the ZMR80 allows it to be tailored to the requirements of a wide
range of different venues with a choice of 2 to 8 inputs, 2 to 12 outputs, paging options and
optional remote panels. Take only the modules and options you require.
The chassis is 19" rack mount 4RU height and will take 1 PSU or 1 Page PSU module, up to 4
twin input modules and up to 6 twin output modules. Unused positions are filled with blank
modules, additional modules up to the maximum can be fitted at a later date.
PSU
The standard PSU does not support paging, for paging a Page PSU is required plus the remote
paging microphone unit.
The PSU module supplies the power to the other modules and includes a mute/priority input on
a 4 pin connector (mating part supplied) allowing system mute (fire alarm for example) and
priority input (for example evacuation announcements) to all outputs.
The front panel has LED's showing supply and system mute status, the rear panel has the 4 pin
mute/priority input connector and a priority input gain trim accessible by screwdriver. Internal
options selectable by jumpers include phantom power for the priority input and connection of
mains earth to 0V rail.
The Page PSU module has a RJ45 connector into which plugs the paging microphone.
Input Module (See drawing PC408 later in manual)
An input module will carry 2 stereo (or mono) inputs which may be balanced or unbalanced, you
may have up to 4 input modules to provide up to 8 inputs.
Mono (Mic) input is on XLR and unbalanced stereo on phono sockets, the selection of input is
on a recessed 6 way switch on the rear panel (position 1 is phono socket input and position 2 –
6 give different gains on the microphone input).
Each input module can have one balanced stereo input, for balanced input use the XLR
connections and set the internal jumper to balanced input. The channel at the top of the module
controls the balanced input, the lower channel will still accept an unbalanced line input on the
phono sockets.
The 8 channels consist of 4 Stereo channels and 4 Mono channels; inputs are assigned to one
of these channels by internal jumpers. The maximum number of stereo channels is 4.
On the front panel each input has volume control, clip indicator LED and screwdriver adjustable
gain trim and two band EQ. On the rear panel inputs are on XLR and phono sockets, input is
selectable by screwdriver operated six way switch which allows selection of line input in position
1 (Phono socket) or Mic and mic input gain in positions 2 to 6 (XLR).
Internal options include phantom power (for microphones), balanced input, mixing two inputs (of
one module) to one buss. Mixing the two inputs to one buss with voice over selected allows
announcements or instruction etc to be clearly heard as the other audio is faded down during
the voice over.
