O MONITOR control
The MONITOR control determines the level of the
signal sent from the corresponding channel to the
MONITOR mixing bus. At the bus, the MONITOR
signals from all channels are mixed and fed to the
master MONITOR control and the rear panel MON
OUT jack. The MONITOR control configuration is
factory preset to pre-EQUALIZER/pre VOLUME.
As a result, the MONITOR signal is independent of
the settings of the channel EQUALIZER and VOL­
UME controls.
@ VOLUME control
The setting of the VOLUME control determines the
level of its corresponding source in the mix of the
signal levels of all input channel sources. As a pre­
caution, if the channel is not being used, it is recom­
mended that the VOLUME control be set to its mini­
mum position to prevent unwanted noise from being
added to the main signal.
Master Control Section
® TAPE TO MONITOR control
The TAPE TO MONITOR control adjusts the level
of the signal received from the rear panel TAPE IN
inputs (RCA pin jacks TAPE IN I and 2).
The adjusted signal is then fed to the master MONI­
TOR control and the rear panel MON OUT jack.
The TAPE TO MONITOR control selectively deter­
mines the output level of tape recorders or other
such devices in the MON OUT signal.
О TAPE IN control
The TAPE IN control regulates the level of the sig­
nal sent from rear panel TAPE IN inputs. The regu­
lated signal is then added to the SP OUT, REC.
OUT and LINE OUT signals. The TAPE IN control
sets the output level of tape recorders or other such
devices in the main program signal.
When recording from the REC OUT jacks, this con­
trol must be set at a minimum to avoid electronic
feedback. As a result, recording and playback can­
not be accomplished at the same time with one tape
machine.
© EFFECTS TO MONITOR control
The EFFECTS TO MONITOR control adjusts the
level of the combined signal received from the rear
panel EFF RTN inputs (1/4" phone jacks EFF RTN
1 and 2) before the signal is fed to the rear panel
MON OUT jack. The EFFECTS TO MONITOR
control selectively determines the output level of
external effects in the MON OUT signal.
® EFFECTS RETURN control
The EFFECTS RETURN control regulates the level
of the combined signal sent from the rear panel EFF
RTN inputs. The regulated signal is then added to
the main program signal. The EFFECTS RETURN
control sets the output level of external effects in
the main program signal.
® EFFECTS SEND control
This control adjusts the output level of the overall
mix derived from the input channel EFFECTS con­
trols and feeds the signal to the rear panel EFF
SEND jack. The EFFECTS SEND control should be
used to optimally match the mixer EFF SEND out­
put level to the input sensitivity of the connected
external effect or signal processor.
© MONITOR control
The independent monitor bus features a master
MONITOR control for adjustment of the overall
monitoring level. This control adjusts the output
level of the overall mix derived from the input chan­
nel MONITOR controls and feeds the signal to the
rear panel MON OUT jack.
© MASTER control
The output level of the main program signal is regu­
lated by the MASTER control. The regulated signal
is fed directly to the rear panel LINE OUT jack and
via the graphic equalizer to the rear panel SP OUT
jacks.
® Graphic Equalizer
For precise response shaping of the SP OUT signal,
the seven-band graphic equalizer provides 12 dB of
boost or cut in each band. There are seven independ­
ent linear controls at the standard ISO center fre­
quencies of 125, 250, 500, Ik, 2k, 4k, and 8k Hz
peaking.
