12V SWITCHING SOCKETS
There are two ‘communications’ options for the
MCX Power Amplifier - 12V switching or ‘EXLINK.’ Only one should be used at a time.
Use these 12V switching sockets only when
connecting to another (non-MCX) system with
a 12V switching facility. Connect the system to
the 12V input of the first MCX Power Amplifier.
After this is done, connect the 12V output of
the first MCX Power Amplifier to the 12V input
on the second MCX Power Amplifier in the
chain.
IN-EXLINK-OUT (RJ45)
Use these sockets with the EXLINK cable
provided to link to other MCX components.
EXLINK facilitates synchronised control of the
‘Power On / Off’, ‘Display On / Off’ and ‘Mode’
functions of the entire MCX system.
Connect the EXLINK OUT on the MCX Pre
Amplifier to the EXLINK IN on the first MCX
Power Amplifier. After this is done, connect the
EXLINK OUT on the first MCX Power Amplifier to
the EXLINK IN on the second MCX Power
Amplifier in the chain. More power amplifiers
may be added to the chain in the same manner.
BALANCED /
UNBALANCED
SWITCH
Press the switch in to select
the balanced input or out for
the unbalanced input.
NOTE: THIS SELECTION
CANNOT BE CHANGED UNTIL
THE UNIT IS POWERED ‘OFF’.
The setting is automatically
detected when the amplifier is
powered ‘ON’

For operating in balanced
mode, use only the

connector to connect to the
MCX Pre Amplifier balanced
output. For operating in
unbalanced mode, use the
unbalanced input.

SPEAKER TERMINALS
Connect your speakers to these speaker terminals.
Two pairs are provided allowing bi-wiring. Please ensure
that the ‘+’ terminal on the speaker is connected to the
red terminal on the power amplifier and the ‘–’ terminal
on the speaker to the black terminal on the power
amplifier.
For bi-wiring, two sets of speaker wires are required.
The jumper wire or plate on the speakers should also be
removed. Please refer to your speaker manual for further
instructions on bi-wiring.
POWER CABLE
SOCKET
Connect the mains lead
provided to this IEC socket.
Insert the mains plug to the
power socket on your wall.
Please push both of the plugs
in properly before switching
the power on.

POWER
Press this to switch the unit ‘on’ or ‘off’. NOTE: THIS POWER SWITCH WILL NOT OPERATE WHEN IN ‘PROTECT MODE’,
when the LED is flashing or when the 12V input is active from another (non-MCX) pre-amplifier.
PROTECT MODE
The MCX power amplifier has the following protection systems:
• Over temperature
• Over current
• DC voltage sensing on the speaker output
If any of these conditions occur, the unit will ‘shut down’, leaving the LED in the display window flashing for 30
seconds before the unit can be switched on again. In cases of over temperature, the unit will need to cool down for 15
minutes before it can be switched on again.

SAFETY
IT IS HIGHLY RECOMMENDED FOR YOUR MCX SYSTEM TO BE PROFESSIONALLY INSTALLED BY YOUR DEALER.
Incorrect installation or inappropriate use of the Exposure MCX Power Amplifier may result in injury due to electric shock.
• Ensure that the voltage rating on the rear panel of this unit matches that of your local mains supply.*
• Ensure that the mains cable and plug supplied with the unit is also correct (Contact your dealer immediately if this is not the case).
• The unit is protected by a mains fuse which is accessible as part of the IEC socket on the rear panel.
•
•
Fuse replacement specifications:
220/240V units
T8A fuse
110/120V units
T16A fuse
The MCX Power Amplifier MUST be earthed.
• Protect the unit against all forms of liquid. Never expose the unit to dripping or splashing, or place objects filled with water, such as vases, on the unit.
• Unplug the unit from the mains supply when not in use for prolonged periods.
• Do not open the unit - there are NO user serviceable parts inside.
• Reduce the volume control on the MCX Pre-Amplifier to minimum before turning this unit ‘on’ or ‘off’.
• Ensure that the unit is switched ‘off’ when connecting or disconnecting speaker and interconnect cables.
*Contact Exposure Electronics for advice on moving your equipment to another country or territory.
CAUTION
For a long and trouble-free life of your Exposure MCX Power Amplifier, please ensure the following:
• Do not short circuit the speaker terminals.
• Do not remove the cover or dismantle the case.
• Do not operate the unit in a damp environment or allow liquids to enter the unit.
• Do not attempt to bypass the mains fuse or replace the fuse with one of a different specification.
• Do not place the amplifier in a position that restricts cooling airflow around the case.
• Do not use abrasive or solvent-based cleaning fluids on the case.
FAILURE TO OBSERVE THESE PRECAUTIONARY MEASURES MAY VOID YOUR WARRANTY.
