13. MONO
The level of the MONO output (9) is set by a rotary fader.
The associated AFL switch with indicating LED monitors the
final output after the fader.
14. AUXILIARY MASTERS
Each of the Auxiliary Send busses is provided with a rotary
master level control and an AFL switch with indicating LED
which monitors the final output after the fader.
15. AUXILIARY OUTPUTS
The Auxiliary Send outputs are driven by ground
compensated amplifiers to a standard
1
⁄
4
" 3 pole ‘A’ gauge
jack socket.
16. TALKBACK
A female XLR-3 connector provides the input for a headphone
mounted, gooseneck or floating dynamic microphone for
TALKBACK to selected outputs. Level is set by the TB
control and three switches route the signal selectively to Mix
L-R, Groups (GRPS) or AUX 1-2.
17. HEADPHONE VOLUME
This control sets the level of the PHONES output at the socket
below the front armrest. Normally this is fed by the Mix L/ R
output, unless an AFL or PFL switch is pressed, in which case
the Mix signal is replaced by the AFL/ PFL signal and the
AFL/PFL LED lights to show that the AFL/ PFL system is
active.
Note that due to the way that the ground compensated
outputs operate, it is possible that a hum might be audible
under AFL listening, which is in fact cancelled on the actual
output. This would indicate that there is a ground loop in
your system which you may wish to correct.
18. MIX FADERS
Master faders for Left and Right mix outputs. Unity gain is at
the top of their travel.
