Input Audio Router.
• Clip Indicator
Output Signal Level Meter (blue)
The mea surement range is from 0 dB to –40 dB with 0.5 dB resolution. The monitors are scaled so
that 0 dB is referenced to the full rated output voltage of the amplifier. The wider left meter is rms
and the right meter is peak for each channel. An output clip indicator is provided.
