nel. The Main Equalization controls are used to "shape" the over final mixed sound to
suit the loudspeakers used and to compensate for the acoustics of the room.
Channel AUX Level Control
The Channel AUX Level control varies the amount of post-equalization, channel signal sent
to the master AUX bus. The output of the AUX bus goes first to the AUX Send Level Control,
then to the AUX Send jack.
Master Section
1. The Main Level control receives the audio signal from the Channel Level controls, adjusts
the gain, and sends the signal to the Main Equalizer. The shaded area on numbers 7 & 8 of
the numbered scale surrounding
the control indicate the optimum
setting region for this control.
Operating the control in this
region will provide the best in
gain and low noise for typical
operation. Not to say that the
control must be operated in this
hi-lighted region, it is only a
suggestion for the best audio
performance. This control is used
to turn down the overall audio
output to the Main Out and to the
power amplifiers. Treat it like the
volume control on a stereo, as it
would adjust the audio signal to
the desired listening level.
2. The Record Level control
receives the audio signal from the
Channel Level controls, adjusts
the gain, and sends the signal to
the Record Out RCA jacks. This
control operates in the same way
as the Main Level control. Your
recording will have reduced noise
if the Record Level is set within
the shaded area and the input
level control at your recorder is
adjusted for a 0Vu level.
3. The AUX Send control receives
the audio signal from the
Channel AUX controls, adjusts
the gain, and sends the signal to
the AUX Send output jack. The
shaded area on numbers 7 & 8 of
the numbered scale surrounding
the control indicate the optimum
setting region for this control.
The AUX Send signal can be used
as a Monitor Send (the audio
signal would pass through a separate power amplifier and power stage monitors), an Effects
Send (the dry audio signal that would enter an effects processor), or through an amplifier to
loudspeakers located in another room (another audio zone).
4. The AUX Return control receives the audio signal from the AUX Return jacks adjusts the
gain, and sends the signal to the Main Level control. The shaded area on numbers 7 & 8 of the
numbered scale surrounding the control indicate the optimum setting region for this control,
but depending on how large the signal is coming from other audio equipment, this control will
probably be set from 3 to 8. The AUX Return signal may come from the output of an effects
processor, or a stereo signal from a CD or cassette player. If the source equipment is mono
insert the signal into the L Mono AUX RTN jack and the audio signal will appear on the left
and right channels of the AUX RTN Level control. If the source equipment is stereo, insert the
signal into the L and R jacks and a stereo signal will appear at the AUX RTN Level control.
