A-B O
UTPUT
The A-B output is an additional stereo/mono output that can be uniquely
configured as either a
separately controllable mix
output, or a
local
loudspeaker monitor
feed.
MODE SWITCH
- This switch is recessed under the panel to prevent
accidental operation. It is operated using a pen tip or similar pointed object.
In the normal up position A-B follows the main L-R mix. When pressed A-B
follows the monitor switchbank + PFL to become a ‘local’ monitor in addition to
the headphones.
POST/PRE
- This recessed switch selects whether the L-R signal fed to A-B
is sourced pre or post the L-R faders.
LEVEL
- Adjust the output level using this control. Up to +10dB of boost is
available above the nominal ‘0’ position.
MONO
- Sums L+R into mono. When A-B is configured as an additional mix
output the MONO switch provides a mono output ideal for centre fill or sub-
bass loudspeaker systems, or mono recording and broadcast feeds. When A-
B is configured as a local monitor the MONO switch lets you check the mono
compatibility of the selected mono source. Alternatively you can feed a local
mono speaker monitor such as an engineers listen wedge.
Here are a few applications of the versatile A-B output:
