unit off.
2. Status LEDs- The red Standby LED will light when the amplifier is turned on. It will stay lit
about 3 seconds while the amplifier circuits stabilize. After that, the red LED will turn off and
the green Normal LED will glow that amplifier is ready to operate.
3. Level controls- Rotate controls clockwise to increase volume.
4. Signal indicators- Light up when the signal input provides greater then 0.2 watts output.

clipping occurs. Consistent lighted of these LEDs can cause both amplifier and speaker
damage. Always avoid clipping.
