There are no user serviceable parts inside the unit.
2. INTRODUCTION
The MZ54 is a 5 input sources/4 zone outputs audio matrix especially designed for multi-zone sound system
applications with independent source selection and volume adjustment. It also manages priority signals and
messages for the diffusion of generic and/or evacuation warnings.
Main characteristics:
4 stereo inputs (two of them accepting microphone/line levels, the last two accepting line levels only).
4 monophonic zone outputs, with 2-band tone controls for each output (adjustable with a screwdriver on front
panel).
Switchable phantom power supply for microphone inputs.
Independent source selection and output volume adjustment (per zone).
Connectivity with remote control panels for zone source selection and volume adjustment.
Local or remote zone control mode selection (from the device front panel or from remote control panels).
Headphones monitoring section.
Euroblock connectors for inputs and outputs (input #1 has also a XLR type connector for MIC/LINE signal).
Removable front panel knobs with safety caps (included) to prevent unwanted access.
3. INSTALLATION REQUIREMENTS
The MZ54 has been especially designed to be installed in a standard 19" rack, taking up 1U.
Since the MZ54 power consumption is very low, it doesn’t require forced ventilation. Nevertheless, you must avoid
extreme temperature conditions and keep the atmosphere of the room in which it is located as dry and dust-free as
possible.
Keep the equipment far from noise sources (variable voltage regulators, motors, etc…) as well as from power
cables.
The MZ54 operates under voltages between 90 and 264 V at 47 to 63 Hz. This device features an over
dimensioned power supply that adapts to the mains voltage in any country of the world with no need to make any
adjustments.
