1. POWER SWITCH

To turn the unit ON or OFF, press the left or right portion of this button. Before turning on the amplifier, check all connections and turn down the level controls. A momentary muting is normal when turning the amplifier on or off. (Caution: Always turn on your power amplifier last, after all your other connected equipment, and always turn off your power amplifier before your other connected equipment.)

2. POWER LED INDICATOR

This LED flashes and then illuminates when the power is turned “ON”.

3. CLIP (PEAK) LED INDICATORS

These LEDs illuminate if any section of the power amplifier’s output are within 3dB of clipping. Occasional blinking of the LEDs are acceptable, but if they remain on more than occasionally you should turn down either

the power amplifier’s level controls or reduce the output level of the preceding component to avoid audible distortion or hard clipping. (Note: Operating the amplifier at hard clipping can result in overheating or may damage your amplifier over a period of time. Amplifiers that are damaged due to such user neglect, or improper operation, are not covered under warranty.)

4. SIGNAL LED INDICATORS

These LEDs illuminate to confirm the presence of an input signal greater than 100 mV at that channel of the amplifier

5. LEVEL CONTROLS

These control the level of signal coming into each channel. The actual voltage gain of the amplifier is shown in dB. Turn these controls counterclockwise if the peak LEDs illuminate steadily (indicating too strong an input signal).

8. L/R CHANNEL OUTPUT CONNECTORS

1/4” (6.3 mm) speaker output jacks. Connect these to speakers with a total impedance of no less than 4Ω per side.

9.BALANCED INPUT CONNECTORS (1/4" TS & XLR) 1/4" (6.3mm) TS (Tip/Sleeve) phone jacks and XLR jacks.
