AB OUTPUT
This is an additional stereo output that can be
configured as a separately controlled mix output or a local loudspeaker
monitor send. A recessed mode switch above the AB level control
selects the source. Use a pen or pointed object to change the setting.
Adjust the output level from fully off to a maximum +10dB boost. The
normal 0dB position is marked on the panel.
With the mode switch in its up position, the LR mix is selected as the
source to the AB output TRS jacks. Factory default setting is post-LR
fader. If preferred you can change this to pre-LR fader by repositioning
internal option jumpers so that the LR master fader movements do not
affect the output. In LR mode the AB output provides an additional
main mix output ideal for independent fill speaker control, 2-track
recording, broadcast feed, booth monitor and so on.
With the mode switch pressed, the console monitor system is selected
as the source. You can use this to feed local monitor speakers to
listen to the source selected on the monitor switch bank interrupted by
PFL. Local speaker monitoring can be useful in theatre and stage
monitoring applications.
AB output relay The AB output routes to its TRS connectors through
a relay which is normally switched on. A remote switch may be wired
to solder pads on the connector circuit card to switch the relay off and
isolate the output. One application is for a broadcast studio where a
booth monitor should be muted when its local mic is live. In this case
the relay would be wired to a micro-switch on the mic channel fader.
For external switching, the relay could be wired to pins on the
REMOTE (user) port on the rear panel.
Console Monitor Comprehensive engineer's headphones monitoring
is provided. Select the source to listen to using the monitor switch
bank.
With no switch pressed the post-fade LR mix is monitored.
Press M to listen to the post-fade M source. Pressing any switch
higher up the bank overrides the previous selection. Pressing Aux
pairs 1-2, 3-4, 5-6 together listens to the two selected auxes as a
stereo pair.
The two console meters display the selected monitor
source signal level.
Pressing channel PFL switches automatically overrides the current
monitor selection with the pre-fade signal from that channel or
selection of channels. The red PFL active indicator lights and the
console meters display the channel signal.
We recommend you use closed ear headphones in the range 30 to
600 ohms designed for live sound monitoring. Headphones around
100 ohms impedance are a popular choice.
WARNING: To avoid damage to your hearing do not operate
any close-to-ear monitoring such as headphones for long periods
at high volume. Continued exposure to high volume sound can
cause frequency selective or wide range hearing loss.
