Press to power ON the amplifier. Press again to power OFF. The POWER indicator lights up when the amplifier is powered ON. 2 TEMP indicator When the temperature of the heat sink exceeds 85 degrees Celsius, this indicator will light red. 3 PROTECTION indicator This red LED indicator lights up for approximately 3 seconds when the amplifier is powered ON, indicating that the soft-start protection system is working. No sound is output during soft-start up. If one of the protection systems is activated during normal use, this indicator lights up and no sound is output. The speaker system is actually disconnected from the amplifier outputs when this indicator lights up. The protection systems are activated when overheating occurs or a DC voltage is present at the amplifier outputs. If the problem is corrected, the protection systems deactivate automatically, this indicator goes out, and normal amplifier operation is resumed. 4 CLIP indicators These red LED indicators light up when the respective channel's output signal distortion exceeds 1% (i.e. clipping). Output signal clipping is usually due to excessive input signal levels. 5 SIGNAL indicators These green LED indicators light up when the respective channel's output signal exceeds 2 Vrms. This is equivalent to 1/2 watt into 8Ω, 1 W into 4Ω. 6 Volume controls These volume controls allow you to adjust the volume level in 31 steps in the range between -∞ dB and 0 dB. To fix the volume setting by protecting the controls, install the included security cover over the controls and tighten the screws in the holes as shown below. 20 25 30 40 ∞ 15 20 10 25 30 6 3 40 0 -dB ∞ 15 10 6 3 0 2
