CLASS D MONO-BLOCK POWER AMP OWNERS MANUAL

Operational Details

1.STATUS LED

Green- Amplifi er is powered “ON”

2.PROTECT LED

Red- If the internal heatsink reaches 80 degrees Celsius the amplifi er shuts down until the internal temperature falls below 75 degrees. It also lights if a direct short is present on the speaker outputs. If this occurs, check for shorted speakers and cycle power to resume operation.

3.REMOTE TURN-ON TERMINAL

Connect to a switched 12 Vdc source such as the headunit’s “remote” or power antenna wire.

4.B- TERMINAL (CHASSIS GROUND)

Connect to a clean, solid chassis ground. Remove all paint and dirt from the chassis connection point. Minimum cable size is 8 gauge. Keep the cable as short as possible.

5.B+ TERMINAL (BATTERY POSITIVE)

Connect directly to the positive battery terminal. Minimum cable size is 8 gauge. Remember to properly fuse this cable within 18 inches of the positive battery terminal.

6.SPEAKER OUTPUTS

Used to connect the amplifi er to speakers. The separate + and – terminals are internally wired in parallel. Minimum speaker cable size is 12 gauge (PG # SS122 or QS122). Lowest recommended impedance is 2 ohms.

7.FUSES

Used to protect the amplifi er. If replacement is necessary, use the same size and type indicated on the endpannel. Never use a fuse with a higher amp rating.

8.REMOTE VOLTAGE DISPLAY INPUT (RMD) Connect the optional RMD Voltage Display to this jack.

9.LPL PORT

This port is for connecting the optional LPL44 Remote Lowpass Level Control knob allowing up to 20dB of volume adjustment.

10.LP FREQ CONTROL

Adjusts the lowpass crossover point for the speaker outputs. The crossover frequency is adjustable from 40 to 300Hz with a 12dB per octave lowpass slope.

11.BASS BOOST CONTROL

This control allows 12dB of boost at 45Hz for the speaker outputs.

12.RCA INPUT

Connect preamp signal cables from the head unit to these terminals. To maximize noise rejection, we recommend using Genuine Phoenix Gold RCA interconnects.

13.AUX OUT

Provides a full range signal for an additional amplifi er.
