CONTROLS
• Input Channels
o
MIC/LINE Switch (Rear Panel)
— Channels 1 & 2
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 & 2
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 EQ LO & HI Controls — Channels 1 & 2
These controls permit individually modifying the re­
sponse of each channei. 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

o AUX Controls
The AUX 1 and AUX 2 controls on the AM602 deter­
mine the level of the signal sent from that channel to
the AUX 1 and AUX 2 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
controls can be used to produce two independent
mixes to feed external effect devices, a performer’s
headphone 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.

0 Channel Fader
This is the main level control for each input channel. It
determines the level of the signal sent from the corre­
sponding input channel to the master stereo buss.
The settings of the input channel faders determines
the “mix” or balance of sound levels between the in­
struments or other sources connected to the inputs.
NOTE: ---------------------------------------------------
If a channel is not being used, its fader should be
set to the minimum position to prevent unwanted
noise from being added to the main program sig­
nals.
