I n p u t m e t e r s

The input meters indicate the signal level in dB below 0 dBFS (0 dB Full Scale), the clip level of the ADC
(analog to digital converter). An input meter still functions when its Input Channel is muted. Ideally, the
highest levels of the signal should illuminate the -6 LED segment, but not the CLIP segment. Occasional
flashing of the CLIP segment may be sonically acceptable.

O u t p u t M e t e r s

Unlike the input meters, the four LED segments of each output meter make up two different meters.

8.4.1

SIG, -12, AND CLIP SIG SEGMENTS

These three segments monitor the signal level in dB below 0 dBFS (0 dB Full Scale), the clip level of the
DAC (digital to analog converter). An output meter still functions when its Output Channel is muted.
Ideally, you want the highest level to illuminate the -12 segment, but not the CLIP segment. You can set
levels lower than this, but understand that you are reducing the signal-to-noise ratio.

8.4.2

LIM SEGMENT

This segment monitors the limiter status referenced to the level set for the limiter threshold. The Lim
segment will indicate limiting even when its Output Channel is muted.

LED Segment

Status

Lim Yellow

On when the limiter threshold is exceeded and there is gain reduction

Occasional flashing is OK. However, if the LED is rapidly flashing yellow or is on steadily a large
percentage of the time, the input signal to the loudspeaker may be exceeding the loudspeaker’s capability
and the volume level should be reduced.
