CONTROLS
• Input Channels
O MIC/LINE Switch (Rear Panel)
— Channels 1 through 6.
This switch sets the input sensitivity of the corre­
sponding input to match line-level or microphone-level
input sources. If you will be connecting a line-level
source such as an electronic keyboard or audio
equipment, set the switch to LINE. If you will be con­
necting a microphone or other low-level source, set
the switch to MIC.
o GAIN Control — Channels 1 through 6.
This control adjusts the input sensitivity of the corre­
sponding input channel. Continuously variable gain
control allows optimum matching with virtually any
microphone or line source.
0 CLIP LED — Channels 1 through 6.
The CLIP LEDs provided on channels 1 through 6 will
light if the signal in the corresponding channel
reaches a level 3-dB below clipping. If a CLIP indica­
tors lights more than just occasionally on high-level
peaks, the GAIN control level or level of the source
connected to the mixer’s input should be reduced to
prevent possible overload distortion.
O EQ LO & HI Controls
These controls permit individually modifying the re­
sponse of each channel. The HI and LO EQ controls
function as follows:
Control Range Freq. Type
HI +15 dB 10 kHz Shelving
LO ±15 dB 100 Hz Shelving
0 AUX Controls
The AUX 1, AUX 2 and AUX 3 controls determine the
level of the signal sent from that channel to the AUX
1, AUX 2 and AUX 3 mixing busses, respectively. The
AUX mixing busses then feed the corresponding AUX
SND level controls and finally the corresponding rear-
panel AUX SND output jacks. The channel AUX con­
trols can be used to produce three independent mixes
to feed external effect devices, a performer’s head­
phone cue system or other system fed by the AUX
SND jacks. All AUX controls are “post-EQ/post-fader,”
meaning that their signal is derived from a point after
the channel EQ stage and fader. This means that the
AUX signal is affected by the channel EQ and fader
settings.
0 PAN Control
The PAN controls assign the signal from the corre­
sponding channel to any desired position in the “ste­
reo sound field.” If a PAN control is set to the maxi­
mum “L” (LEFT) position, the signal from that channel
will appear only at the left-channel output (ST QUT L).
If the PAN control is set fully “R” (RIGHT), the signal
will appear only at the ST QUT R output jack. If a
PAN control is set to its center position, then the sig­
nal from that channel will appear equally at both the
left- and right-channel outputs, and the sound will
appear at the center of the stereo sound field (at a
point midway between the two stereo speakers).
Qther PAN control settings place the sound at posi­
tions roughly corresponding to the PAN control setting
by varying the level of the signal sent to the left- and
right-channel outputs.
