Mounting and Ventilation
The
SRl10 Professional Monitor Mixer is designed
for rack-mounting in a standard 19 in. (483 mm) audio
equipment cabinet rack and is supplied with the nec-
essary mounting hardware (see Figure C). If possible,
the
SR110 should be rack-mounted above its as-
sociated
SRl 01 or SR109.
The SR110 may also be operated while mounted in
a Shure
A105A Carrying Case. The A105A will accept
panel heights of
7
in. (178 mm), providing space for
one
SRl10 and one SR109 Professional Mixer.

OVERALL DIMENSIONS
No special precautions are required for ventilation.
The
SRl10 may be operated over a temperature range
of
-7" to 54°C (20" to 130°F) in continuous duty with-
out derating.
Power Supply
The
SR110 Professional Monitor Mixer is furnished
with a three-conductor power cable and three-prong
grounded plug (11). Connect the
SR110 to an outlet
which supplies 108 to 132 volts ac, 50/60
Hz
power.
The nominal power consumption at 120 volts under
normal operating conditions is 3 watts maximum (0.025
amperes at 120 volts). If extension cords are required
to supply power to the
SR110, a high-quality, 18-gauge
or larger cord should be used.
The
SRl10-2E is furnished with a three-conductor
line cord without a power plug. Obtain a suitable three-
pin male power plug and attach it to the line cord. The
plug should be installed by qualified service personnel.
(Brown lead goes to "hot" or "live" terminal, blue lead
to neutral terminal, and
green/yellow lead to ground
or earth terminal.) Select proper operating voltage
(115V for 105-125V supply or 220V for 210-250V sup-
ply) using the VOLTAGE SELECTOR Switch (14).
A POWER-OFF Switch located on the front-panel
MASTER Volume Control (3) controls the application
of ac power to the
SRl10, and a red indicator lamp
(2) indicates the power-on condition.
Functional Circuit Description
The inputs to the SRllO Professional Monitor Mixer
enter through the 11-pin
male connector located on
the cable (8) (see Figure D). The 11-pin female
