MON FORMAT SEL
The top alpha shows the current sound pressure level (SPL) which will be 82dB, 85dB, 88dB or Vari (User)
according to the selection on the Control Room panel and the bottom alpha shows the trim set with the TRIM +
and TRIM - keys.
Mono and Academy Filter
To monitor a mono mix of the surround outputs press the MONO key.
The integral LED will illuminate red. and the output to all the speakers except Front Centre will be cut.
A true mono mix of the surround monitor output will be heard on the Front Centre speaker.
To engage the Academy Filter press the ACAD key.
The Academy Filter is a standard filter which cuts high and low frequencies for mono output.
To trim the Monitor Outputs press the TRIM + or TRIM - key.
Up to +/- 10dB of trim is available. The applied trim is shown in the bottom alpha on the Mon Format Sel
section.
If the TRIM + or TRIM - key is held down then the trim level will change continuously. For safety reasons, when
this is done the trim stops at 0dB and the key must be pressed again to carry on increasing (or decreasing) the
level.
To swap to Control Room Monitor Source press the SWAP SPKRS key or the EXT key on the SELECT panel.
The integral LED will illuminate red and the Swap Speakers relay will close.
The LED(s) for the currently selected Stem(s) in the Stem Sel section will flash.
The output for front left and front right will be sent to SEL 1.
The output routed to SEL 1 (if any) will appear on the front left and front right speakers and the remaining
surround speakers will be cut.
The SEL1 system path is often used as an output to near-field speakers. If near-field speakers are being used (to
test mixes on domestic quality speakers) then the output format can be changed (e.g. using Lt-Rt or MONO) to
test compatibility with non-surround domestic systems.
LCRS Pre and Post Decode Monitoring
Both of these functions use inserts to switch the Film paths through external equipment for encoding and
decoding.
The Lt-Rt and POST DECODE keys are latched with each other so selecting one will turn the other off if it was on.
To monitor the Left Total and Right Total output from the Dolby matrix encoder press the Lt-Rt key.
