Metering section:

L & R METERS – two 10-segment LED bargraph meters indicating the signal

level of the stereo master output are tted in the Stereo Master Output Module

area. The meters show the post-fade signal level relative to 0 dBFS – i.e., the

main stereo signal leaving the mixer. The bottom LED is green and illuminates at

-54 dBFS, and thus acts as a “signal present” LED. The top three LEDs are red,

the uppermost indicating the digital peak level of 0 dBFS. The remainder of the

LEDs are yellow.

GR METER – an 8-segment LED bargraph meter indicating the instantaneous

gain reduction being applied by the dynamics section’s compressor.

GT – not used.

LIM – a red LED which illuminates when the signal in the channel exceeds the

limiter threshold.

Mute and Solo:

SOLO – routes the stereo master signal to the internal AFL buss, to permit

the signal to be monitored without otherwise interrupting the mixer’s routings.

The operation of the Solo system is controlled from the Solo Logic section, see

page 63.

MUTE – mutes the master stereo output, the mono sum output and the stereo

tape output. To be used with caution!
