3. Clip limiter switch

Turns the clip limiter “ON” (switch IN position) or “OFF” (switch OUT position). (See page13).

4. Input signal XLR

.

The Neutrik Combo jack is used which also features a _” TRS phone jacks. (Pin 2 is “hot”, see page10).

5. Link switch

. Allows a single input to drive channels B and C simultaneously.

7. Link / bridge switch

. Allows a single input to drive channels A and B and / or channels C and D

simultaneously. Also used for bridged operation of channel pairs (See page 6).

9. AC Mains cable.  WARNING!

A label just below the mains cable on the rear of the amplifier indicates the selected AC
mains operating voltage. Connect the mains cable only to the AC source referred to on the
label.

Gain

The gain of the MA200Q is fixed at 32 dB.

Sensitivity

Sensitivity is volts (rms) or dBu (referred to 0.775Vrms) that are required to obtain full output power. As
the output power varies with the load impedance, the table below lists sensitivity versus load
configuration.
