The SCM262 Stereo Mixer is designed for restaurants, classrooms,
corporate training, aerobics classes, and othersituations where a paging/
public announcement system
is
combined with background music or oth-
er program material.

plugged in and receiving power.
NOTE:
The SCM262 does not have a power switch.
To
turn
the unit off, unplug the power cord or use
an

strip with aswitch. However, it
can
remain plugged
in
as it uses

ically lowerthe gain

one
of the microphones.
DUCKING LEVEL: Adjusts the amount

duction when ducking is activated.
APPLICATIONS
General Application
This is a general setup formost situations which require the combined
use
of professional microphones and consumerstereo equipment. Using
this general setup, there are several otheroptions available forfurtherad-
justing the SCM262 for your sound system. See the diagram on the fac-
ing page.
1. Turn all gain controls counterclockwise.
2. Connect LIR
STEREO INPUTS of the SCM262 to the L/R stereo
outputs
of the desired stereo audio equiment (CD players, VCRs,
televisions,
juke boxes, etc.).
3. Connect microphone(s) to the
MIC INPUTS on the SCM262 .
4. For microphones which require phantom power, such as con-
denser microphones, place DIP switch 7 in the down position
(phantom
power on).
5. Connect the LIR outputs of the SCM262 to the LIR inputs of the
amplifier.
NOTE:
If you are using a consumer stereo amplifier, use the
AUX OUTs. Ifyou are using a professional audio power
amplifier, use the LINE
OUTs . The MIG/LINE and AUX
OUTPUTs can be used simultaneously to feed two separate
amplifiers.
6.
Apply power to the mixer by connecting the supplied power cable
between the
power connectoron the mixer and the appropriate
AC power supply. The green POWER LED will illuminate to indi-
cate that the
mixer is powered on.
*NOTE: The SCM262 has no power switch. It is designed to
be plugged into a power strip which supports the whole sound
system. A typical power strip will have a power switch, so that
when the power strip is powered on, the SCM262 is powered
on.
*Power Switch, country dependent.
Paging
with Ducking Application
With Ducking on, the SCM262will automatically sense when someone
is talking into one
of the microphones and lowerthe volume of the music
6
STEREO 3 JUKEBOX MUTE: This DIP switch turns the Juke Box
Mute feature on oroff. When on, anysource connected to STEREO 3will
mute STEREO 1 and 2 inputs.
PHANTOM POWER: When
in the down position, this switch activates
a 12 V phantom power source for condenser microphones. Phantom
power does not affect the operation
of balanced, dynamic microphones,
so one can be connected to the SCM262
in combination with a condenser
microphone.
so the talker can be heard more clearly. Once the talker is finished, the
music resumes.
NOTE: Use a microphone with an ON/OFF or pushbutton
switch for the Paging with Ducking Application. A microphone
without a switch will false-trigger, causing unwanted
interruptions
in the program material.
1. Connect the SCM262 to the sound system as described
in Gen-
eral Application.
2. Set DIP switch 3 or 4 to the down position to activate ducking for
microphone channel 1 or 2, respectively.
3.
Set DIP switch 5 position. The Down position sets the ducking so
that the program sound is lowered 20 dB when someone uses a
microphone. The
Up position sets the ducking so that the pro-
gram sound is muted when someone uses a microphone.
Jukebox Mute Application
In this application, designed primarily for Jukeboxes, any sound
source connected to the STEREO 3 channels will automatically mute any
sound coming overthe STEREO 1and 2 channels. This way, a CD play-
er can be playing music, and then when someone plays a song on the
Jukebox, the SCM262 will automatically mute the CD player channels
and switch to the Jukebox. STEREO 1 and 2 channels will remain muted
for about 30 seconds after program material is finished, to allow thejuke-
box time to move on to the next song.
1.
Connect the SCM262 to the sound system as described in Gen-
eral Application.
2. Connect the LIR audio outputs of the jukebox to the L/R inputs of
STEREO 3.
NOTE: This feature is designed especially for use with
jukeboxes, but will work for any equipment connected to
STEREO
3.
3. Set DIP Switch 6 to the down position (Jukebox Mute on).
NOTE: Ifthe ducking application is used in conjunction with the
Jukebox Mute application, then activated
mi crophones will
mute or duck the STEREO 3 input.

INTERNAL MODIFICATIONS
WARNING! Voltages in this equipment are hazardous to life. No user-serviceable parts
inside. Refer all servicing and modifications to qualified service personnel.
DISASSEMBLY
To access the printed circuit board (pc board) for internal modifica-
tions, use the following steps:
1. Unplug
the power cord.
2. Remove
the knobs and retainer nuts from the front panel.
3. Remove the
two screws at each bottom corner of the front panel.
4. Remove the four screws at each corner of the back panel.
5. Slide the back panel and pc board out from the rear of the chas-
sis.
CAUTION: When reassembling the SCM262,
DO NOT
OVERTIGHTEN the knob retainer nuts. Use a minimal amount
of force to secure the nut (0.6-0.8 N-m (5-7 in-lb)). Damage to
the internal components will result
if too much force is used.
Mono Mixer Modification
This modification allows all the inputsto bemixed to a single monosig-
nal sent over both the left and right outputs.
Shortjumper X203.
Phantom Power Disable
This modification disables the phantom power per channel.
To disable the phantom power from mic 1, remove resistor R121 . To
disable the phantom power from mic 2, remove resistor R122.
15 dB Mic PreamplifierPad
When a microphone has an extremely high signal, getting the desired
gain might be difficult-- a small turn
of the gain control might change the
sound from a whisperto deafeningly loud. This modification adds a 15dB
Mic preamplifier pad to allow more accurate gain adjustment with ex-
tremely high microphone signals.
Remove R160 (mic 1)
or R183 (mic 2).
Hard Panning MIC Channels
To remove MIC 1from the left outputs, remove R912. To remove MIG
1 from the right outputs, remove R913.
8
To remove MIG 2/LINE 2 from the left outputs, remove R910. Tore-
move MIG 2/LINE 2 from the right outputs, remove R911.
Low-Cut Filter
To eliminate the 80 Hz, low-cut filter, remove resistor R501 (mic 1), or
resistor R519 (mic 2). Place a 10 to 33 J..tF capacitor in X501 (mic 1) or
R502 (mic2). The polarity
of the capacitordoes notmatter.To changethe
frequency ofthe low cut filter, remove resistor
R501 (mic 1) or R519 (mic
2), and place the proper capacitor into X501 (mic 1)
or X502 (mic2)to get
the desired cornerfrequency.
The following tables list the low-cut frequency corners for some
of the
most common capacitor values:

Ducking Depth
This modification adjusts the level of ducking depth attenuation of the
input channels when ducking is activated.
The aux ducking depth may be changed by removing resistor R213
and inserting a resistor into jumper X202. Use the following tables to de-
termine the proper resistor value for the desired ducking depth.

Ducking Threshold
This modification adjusts the threshold for activating the ducking cir-
cuit.
The ducking threshold can
be raised or lowered by first removing re-
sistor R333, and then placing a resistor (R)
at jumperX303. To lowerthe
ducking threshold, use a resistor value (R) less than 2k ohms. To raise
the ducking threshold, use a resistor value (R) greater then 2k ohms.

brackets.
The
brackets should straddle the recessed edges on on
the top and bottom
of
each chassis. Fasten them using eight (8)
bracket screws.
NOTE: Be sure to use both straddle brackets-one
on
the top
and
one on the bottom.
