INPUT CHANNELS
@ PAD switch
This switch attenuates the signal applied to the cor-
responding channel input by 15 dB prior to the head
amplifier. The 15 dB switch effectively increase the
range of input signal levels that can be handled by
the mixer, preventing overloading of the input cir-
cuitry when receiving high-level signals. The pad is
ON when the 15 dB switch is in the =

These three controls permit selective modification
of the frequency response for each channel. The

@ EFFECTS control
The EFFECTS
contro! determines the level of the
signal sent from the corresponding channel to the
EFFECTS
mixing bus.
At the bus, the EFFECTS
signals from all channels are mixed and fed to the
EFFECTS
SEND
control and the rear panel EFF
SEND jack. The EFFECTS control configuration is
factory preset to post-EQUALIZER/post-
VOLUME.
As aresult, the EFFECTS signal is directly depend-
ent on the settings of the channel EQUALIZER and
VOLUME
controls.
@ 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.
PAN control
The PAN control determines the position in the stereo
sound field at which the sound from that channel is
heard. Rotated fully counterclockwise the channel
signal will be delivered from the left output only,
and will be heard at the far left of the stereo sound
field. If the PAN control is turned fully clockwise,
the sound from that channel will appear at the far
right of the stereo sound field. If the PAN control is
set at its center position, the channel signal will be
sent equally to both the left and right channels, causing
the sound to appear at the center of the sound field.
Intermediate PAN control settings cause the sound
to be heard at the corresponding position.
Channel fader
This is the main level control for each input chan-
nel. The setting of the fader control determines the
level of the channel
signal in the overall master
stereo output signal. As a precaution, if the channel
is not being used, the fader control should be set to
the lowest level to prevent unwanted
noise from
being added to the main signal.
