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:

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/postfader,” 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.

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

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.
---------------
------------------------------------
• Master Control Section
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).

CONTROLS & CONNECTORS
® SUB IN/OUT Jacks
These four jacks and selector switch permit “cascad
ing” two AM602 units to increase the number of avail
able input channels to 12. When two AM602 units are
cascaded, one functions as a “sub-mixer” and the
second as a “master mixer.” The input channels on
the sub-mixer operate normally but the master section
controls are not used. The input channels of the mas
ter mixer also function normally, and its master sec
tion controls the entire system. That is, the MASTER
fader, AUX SND and AUX RTN controls of the master
mixer function for all 12 input channels. The SUB IN/
OUT switch determines whether the SUB IN/OUT
jacks function as inputs or outputs, and thus whether
the AM602 functions as sub-mixer or master mixer.
For sub-mixer operation the SUB IN/OUT switch

should be set to the “OUT” position, while for master
mixer operation it should be set to the “IN” position.
The diagram below shows the proper connections
and switch settings.
r NOTE:
For normal single-mixer operation the SUB IN/OUT
switch should be set to the “IN” position. In this
condition the SUB IN/OUT L, R , AUX 1 and AUX 2
jacks function as inputs, and can be used to feed
external line-level signals into the mixer’s stereo
master buss and AUX busses. If the SUB IN/OUT
switch is set to the OUT position, however, the
SUB IN/OUT L and R jacks can be used as “REC
OUT” jacks, providing a line-level signal for record
ing, etc.
----------------------------------------------------
IMPORTANT NOTES
MAKE SURE THE MIXER’S POWER SWITCH IS OFF OR THE MASTER FADER IS SET TO MINIMUM WHEN
CONNECTING OR DISCONNECTING ANY CABLES.
ALWAYS TURN THE MIXER’S POWER ON OR RAISE THE MASTER FADER AFTER TURNING ON CON
NECTED SOURCES SUCH AS ELECTRONIC INSTRUMENTS, ETC.
NEVER CONNECT THE SPEAKER OUTPUT OF ANY AMPLIFIER TO THE MIXER’S INPUTS UNLESS A SUIT
ABLE HIGH-LEVEL ATTENUATION PAD OR “DIRECT BOX” IS USED TO LOWER THE SIGNAL’S LEVEL.

SAMPLE APPLICATION
A Small Sound Reinforcement System
In this small sound reinforcement system the required sources are connected to the appropriate input channel connec
tors. The AUX SND 1 output is connected to a digital signal processor for reverb and other effects, and the stereo
output from the signal processor is returned to the AUX RTN 1 connectors. The AUX 1 controls can thus be used to set
up the required effect mix..The AUX 2 controls are used to provide a separate monitor mix for the performers on stage.
The AUX SND 2 output is therefore connected to a power amplifier driving the on-stage monitor speaker system. The
main house power amplifier/speaker system can be fed by the ST OUT L and R outputs. In this system a tape player
is connected to the AUX RTN 2 inputs to provide background music during intermission or recorded accompaniment for
the performance.
