Metering section:
L & R METERS – two 10-segment LED bargraph meters indicating the signal
level of the stereo master output are fitted 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
MUTE – mutes the master stereo output, the mono sum output and the stereo
tape output. To be used with caution!
