CONTROLS & CONNECTORS
CONTROL PANEL
REAR PANEL
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:
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.

O 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 souhd levels between the in
struments or other sources connected to the inputs.
NOTE: ----------------------------------------------------
If a channel is not being used, its fader shouid be
set to the minimum position to prevent unwanted
noise from being added to the main program sig
nals.
• Master Control Section
@ AUX SND Controls
These adjust the overall output level of the AUX 1,
AUX 2 and AUX 3 “mixes” set up using the corre
sponding channel AUX controls. AUX SND 1 sets the
overall level of the AUX 1 mix signal appearing at the
AUX SND 1 jack, AUX SND 2 sets the overall level of
the AUX 2 mix signal appearing at the AUX SND 2
jack, and AUX SND 3 sets the overall level of the
AUX 3 mix signal appearing at the AUX SND 3 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.
® REC OUT Control
This control adjusts the level of the master stereo
signal available at the rear-panel REC OUT L and R
jacks. When the REC OUT L and R jacks are con
nected to the inputs of a tape recorder, the REC OUT
control can be used to set the optimum recording
level (in conjunction with the tape recorder’s record
level controls, if available).
® Level Meters
The AM802 features independent 5-element LED
peak level meters for the left and right channels. The
LED elements correspond to levels of -20, -10, -3, 0,
and +3 dB. If either of the +3 dB elements 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 STEREO L and R faders are set to
minimum when turning the POWER switch ON.
O 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.
<E) STEREO L & R Faders
The STEREO L and STEREO R faders independently
adjust the level of the signal sent from the left and
right master stereo busses to the L and R ST OUT
jacks.
<D 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.

CONNECTORS
CONTROLS & CONNECTORS
® INPUT Connectors
The AM802 has a total of 8 input channels, each of
which has a single 1/4" monaural phone INPUT jack.
See “ 1 . MIC/LINE Switch” for a description of the
MIC/LINE switches associated with INPUT jacks 1
through 6. 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.
NOTE: ----------------------------------------------------
Since channels 7 and 8 are designed to handle
stereo signals, they have two input jacks each (L
and R) rather than the single input, jacks provided
on all other channels.
® AUX SND Jacks
These jacks deliver the AUX 1, AUX 2 and AUX 3
mixes, respectively, to feed an external signal proces
sor, performer’s headphone cue system, a monitor
system, etc. Nominal output level and impedance of
the AUX send jacks are -10 dB/10 kohms.
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.
® REC OUT L and R Jacks
These output jacks are primarily intended to feed the
AM802 master stereo signal to a tape deck for record
ing, although they can be used to feed other audio
equipment if required. The output signal level at the
REC OUT L and R jacks is controlled by the REC
OUT control in the mixer’s master section.
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).
<D 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
IMPORTANT NOTES
MAKE SURE THE MIXER’S POWER SWITCH IS OFF OR THE STEREO FADERS ARE SET TO MINIMUM
WHEN CONNECTING OR DISCONNECTING ANY CABLES.
ALWAYS TURN THE MIXER’S POWER ON OR RAISE THE MASTER FADERS 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 chahnei connec
tors. The AUX SND 1 Output is connected to a digitai signai 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 and AUX 3 controls are used to provide two different monitor mixes for groups
of performers on stage — one for the instrumentalists and one for the vocalists, for example. The AUX SND 2 and AUX
SND 3 outputs are therefore connected to power amplifiers driving the on-stage monitor speaker systems. 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.
