Quick Start

Basic MA 4 operation is straightforward:
1. The universal switching power supply works with 100 to 240 VAC, 50/60 Hz.
2. Make sure the front panel power switch is off (the unit consumes 5 watts in standby mode).
3. Connect balanced inputs (rear panel).
4. Set SENSITIVITY controls to +22 (see why on page Manual-2) (rear panel).
5. Turn the Downward EXPander ON (rear panel).
6. Set COMPressor to 10 dB (rear panel).
7. Select the appropriate HIGH PASS filter frequency (20, 40, 60 or 80 Hz on rear panel).
8. Connect speaker loads (rear panel).
9. Make sure you have adequate ventilation around the unit – see Safety Instructions.
10. Turn ON the front panel power switch. You're good to go!
Metering shows the status of the amplifier at a glance (see page Manual-3). Headroom (with any load), dynamics control, Fault status
and Load status are indicated for each channel.
