O AUX SND Controls
These adjust the overall output level of the AUX 1 and
AUX 2 “mixes” set up using the corresponding chan-
nei AUX controis. AUX SND 1 sets the overail level of
the AUX 1 mix signal ap|3earing at the AUX SND 1
jack, and AUX SND 2 sets the overall level of the
AUX 2 mix signal appearing at the AUX SND 2 jack.
These controls should be used to optimally match the
AUX SND output level of the mixer to the input sensi­
tivity of the external signal processing device or power
amplifier used.
© AUX RTN Controls
These controls adjust the level of the signal received
at the corresponding rear-panel AUX RTN jacks and
mixed into the main program on the master stereo
buss. Stereo inputs are provided for each AUX RTN
input, providing compatibility with the many mono-in/
stereo-out signal processors currently available.
© MASTER Fader
The MASTER fader controls the master output levels
of both the left and right channels, and thus the level
of the signals appearing at the ST OUT L and R jacks.
© PHONES Control
Adjusts the level of the master stereo program signal
applied to the rear-panel PHONES jack. Use the
PHONES control to set the most comfortable head­
phone monitoring level.
© Level Indicators
The AM602 has left- and right-channel SIGNAL and
CLIP LEDs. The SIGNAL LEDs light when a signal of
sufficiently high level is detected in the corresponding
channel, and the CLIP LEDs will light if the signal in
the corresponding channel reaches a level 3-dB be­
low clipping. If the either of the CLIP indicators lights
more than just occasionally on high-level peaks, the
fader levels or levels of the sources connected to the
mixer’s inputs should be reduced to prevent possible
overload distortion.
© POWER Switch (Rear panel)
Flip to the ON position to turn power ON, or to the
OFF position to turn power OFF. The POWER indica­
tor LED will light when the power switch is turned ON.
- CAUTION: ----------------------------------------------
Make sure the MASTER fader is set to minimum
when turning the POWER switch ON. '
CONNECTORS
© INPUT Connectors
The AM602 has a total of 6 input channels, each of
which has a single 1/4" monaural phone INPUT jack.
See “O MIC/LINE Switch” for a description of the
MIC/LINE switches associated with INPUT jacks 1
and 2. When a MIC/LINE switch is set to MIC, the
input level and impedance for that channel are set to
-50 dB/50—600 ohms. When set to LINE, the input
level and impedance are -10 dB/600 ohms. The input
level and impedance for INPUTS without MIC/LINE
switches are -10 dB/600 ohms.
© AUX SND Jacks
These jacks deliver the AUX 1 and AUX 2 mixes,
respectively, to feed an external signal processor, a
monitor system, etc. Nominal output level and imped­
ance of the AUX SND jacks are -10 dB/10 kohms.
© AUX RTN Jacks
The output from signal processors fed by the AUX'
SND jacks can be returned to the master stereo buss
via these jacks. Stereo AUX RTN jacks offer compati­
bility with the wide range of mono-in/stereo-out signal
processors currently available. The AUX RTN jacks
can also be used to add external signals other than
the output from signal processor to the stereo buss.
Nominal input level and impedance are -20 dB/600
ohms.
© PHONES Jack
The PHONES jack delivers the mixer’s master stereo
program signal to a pair of standard 8 ohm stereo
headphones. The PHONES control adjusts the head­
phone monitoring level.
© ST OUT L & R Jacks
The main outputs from the mixer’s stereo buss. These
1/4" monaural phone jacks deliver the stereo buss
signal at 0 dB/10 kohms (nominal).
