PLACEMENT FOR PROPER VENTILATION
The MCA Series Amplifier requires a minimum of 12” (30cm)
of unobstructed air space above the top cover. Make sure
that the ventilation slots on the top and bottom remain
unobstructed by any object. Do not stack any other
component on top of the MCA Series Amplifier or block the
ventilation slots in any way. Also, be sure that the amplifier is
placed on a secure, hard and level surface, NOT on carpet.
In the event of overheating, your MCA Series Amplifier is
equipped with a thermal shut off feature. The amplifier will
remain off until the temperature falls below the shut off
threshold. Once this condition is met, the amplifier will reset
itself and it can be powered on again.
OPERATION
Before plugging in the MCA Series Amplifier, check to see
that it is configured for the correct AC line voltage for
country of use. The operating AC line voltage is indicated on
the side of the shipping box and on the rear panel. If the
amplifier is set incorrectly for the country in which it is to be
operated, contact the dealer or distributor in your area.
Connect loudspeakers to the appropriate post as described
in the Speaker Connection Posts section above.
The remaining input signal connection is made with
connectors from a suitable Preamp or SSP such as the
Anthem AVM 20.
Connect the preamp/SSP outputs to the appropriate MCA
Series Amplifier inputs (F in figures 2 to 4) for each channel.
Select an appropriate ON MODE for your MCA Series
Amplifier. If TRIGGER mode is selected, connect a standard
3.5mm Mini Plug trigger cable between your MCA Series
Amplifier and the upstream control component, such as the
Anthem AVM 20.
Connect the Detachable Power Cord to the AC Power Cord
Socket (E in figures 2 to 4). Plug your amplifier into the AC
power source.
After you ensure your preamp or SSP has the volume turned
down or muted, you can power up your MCA Series Amplifier,
which is now ready for operation.
BREAK-IN TIME
As with all audio electronic products, the ultimate sonic
character of the MCA Series Amplifier will not be realized until the
unit receives a minimum of approximately 70 hours of signal
break-in time (i.e. the amplifier is on and outputting a signal).
TROUBLESHOOTING
If at any time the MCA Series Amplifier fails to work properly,
consult this checklist:
1. Check that the AC Detachable Power Cord is plugged into
the Detachable Power Cord Socket (E in figures 2 to 4) and is
connected to a live source of AC power. For instance, if using
a power bar, check that the bar is turned on.
2. Ensure that all Input and Output connections are secure for
a proper electrical contact.
3. Ensure that the amplifier is configured for the appropriate
ON MODE in your system setup (D in figures 2 to 4).
4. Check the internal fuse(s).
If a problem still persists, please contact your authorized
Anthem Dealer directly.
