1. POWER SWITCH:					4. POWER INDICATOR LED:

This switch turns the amplifier on in the up position ("I" pressed in ) and off in the down position. When AC power is applied to the amplifier, the power indicator led (#4) illuminates.

2. LEVEL CONTROL (CH-1) & MONO:

This rotary potentiometer controls the sensitivity or gain of (CH-1). Set them to the level needed for the desired output. When amplifier is set in the bridge mono mode, only this level control (CH-1) is active in this mode.

3. LEVEL CONTROL CH2:

This rotary potentiometer controls the sensitivity or gain of CH2. Set them to the level needed for the desired output. When amplifier is set in the bridge mono mode, this level control is not active.

This Led illuminates when AC power is applied by means of the Power Switch (#1)

5. PROTECT INDICATOR LED'S:

These LED's illuminate whenever the internal protection relay for the channel is activated. The protection relay is activated for a short period upon initial turn-on and at turn-off to prevent transient "spikes" from being reproduced through your speakers. A protect condition is also indicated if the unit gets too hot, or if DC voltages are present at the output. During thermal protection, both channels are shut down. In the event of DC voltage on the output, only the affected channel will be disconnected. The circuitry associated with the LED indicators provides valuable protection for both the amplifier and your speakers.
