The –30dB LED lights green when an output signal level exceeds about -30dB. 
The –10dB LED lights green when an output signal level exceeds about -10dB.
The CLIP LED lights amber when an output signal clips (distortion occurs). 
NOTE:  Do not operate the unit with the CLIP LED continuously on.

Decrease the volume level to avoid signal clipping.

4. PROTECTION INDICATOR

PROT indicator lights red when the protection circuitry is activated.
When the power is turned on, the PROT indicator lights for about 2 seconds.

5. VOLUME CONTROL

Adjust the input level of each channel.
To increase the volume level, turn the volume clockwise.
The volume control range can be set both 0dB ~ -12dB and 0dB ~ minimum by changing the volume range
setting switch internally. (See page 8).
