Ventilation Requirements
Important: Position the MC series amplifier in a
way that ensures good airflow. Make sure its
vents on the top and sides are not blocked, as
proper ventilation is crucial for its operation.
Avoid placing it in areas with excessive dust or
allowing dust to accumulate and clog the vents.
Do not place the MC series amplifier directly
above or below any device that generates heat,
such as an audio amplifier.
Ensure there is a minimum of 2 inches of open
space around the sides of the unit, with free
airflow
above
it.
Maintain
approximately 1.5 inches above and below the
unit, especially if it's mounted in a rack.
Electrical Power
The MC series amplifier operates on 24VDC, and
its adapter is compatible with 110VAC, 50/60 Hz.
For the best performance, connect it and any
related equipment to a dedicated 20-amp circuit.
To reduce interference from electrical noise,
consider using a power line conditioner.
Important Considerations
Always disconnect the power cord before
making any connections.
Ensure all connections are correct and the
wiring polarity is accurate.
Keep power cords away from signal cables to
avoid interference.
Use high-quality signal audio cables
Label all wires clearly at both ends, indicating
their room location.
Avoid placing speaker or signal cables near
electrical wires. If they must run parallel, keep
them at least two feet apart. Cross electrical
lines at a 90° angle.
Do not connect the main power cord until all
other connections are verified. Connecting or
disconnecting wiring while the system is on
can cause damage or erratic performance.
Touching live wiring can lead to electrical
shock.

Description
The MC-2120 is a digital class-D power amplifier that
utilizes advanced switching power technology for
minimal
power
consumption
efficiency of up to 85%. This efficient design not only
saves rack space but also produces less heat, thereby
enhancing its performance longevity. With a 120W
output distributed across two channels, this amplifier
serves as an economical solution for dual-zone,
multiple-source public address systems. It supports
both high impedance 70V and low impedance 8 Ohms
outputs, making it suitable for PA fixed installations as
well as Hi-fi stereo sound setups.
Each channel features two balanced line inputs with
phoenix connectors and gain control. It also offers
separate high-pass filters for each channel, which can
be activated or deactivated using a dip switch. The
amplifier automatically enters standby mode if no
signal is detected for one minute and quickly resumes
operation upon signal detection.
Visual indicators for protection, clip, input, and output
statuses facilitate easy monitoring. It is also equipped
with comprehensive safety features, including short
circuit, overload, high temperature, clip, and DC
protection.
