OPERATION AND

DESCRIPTION

The Shure Model SR110 Professional Monitor Mixer

is a rack-mounted, eight-channel, line level mixer, de-

signed as an accessory for the Shure Model

SRlO1

Series 2 Audio Console or SR109 Professional Mixer.

It can also be used with similar equipment when a

separate stage monitor mixer is desired to be added

to a sound reinforcement system. The

SR110 can also

be used in multi-track recording applications as a re-

cording mix panel or in stereo broadcasting.

Interconnections between the

SR110 and the SRlO1

or SR109 are made through a single multi-pin con-

nector and cable permanently attached to the SRllO.

The

SR110 also contains a matching female multi-pin

connector for "stacking" additional

SRllOs.

The SR110 provides eight high-impedance, unbal-

anced, line level inputs to its mixing circuitry, and one

high-impedance, unbalanced line level input to its

output selector switch for monitoring program mate-

rial. The output of the

SR110 is a 600-ohm balanced

line level with one three-pin male professional audio

connector and two standard

'/4

inch three-circuit

phone jacks, connected in parallel.

The front panel of the SRllO contains eight rotary

volume controls for channel gain, and a combination

rotary master volume controllpower-off switch. An

output selector slide switch, headphones jack and

neon power indicator lamp are provided. Silicon

transistors and other solid-state devices are used

throughout. All components are of the highest quality,

and are operated well within their respective ratings

to assure maximum reliability under normal use con-

ditions.

The

SR110 and SR110-2E are identical except that

the SRllO operates from 108-132 Vac, 50160 Hz, and

the

SRllO-2E operates from either 105-125 or 210-250

Vac, 50160 Hz (switch-selectable).

SR110 Mixers are supplied with four rack-mounting

screws for mounting in standard 19 in. (483 mm) audio

equipment racks or in an optional Shure

A105A Carry-

ing Case (mounted with an

SR109). In addition, the

SR110-2E is supplied with a detachable ac line cord

(without power plug). The

SRl10 (only) is listed by

Underwriters' Laboratories, Inc., and is listed by

Canadian Standards Association as certified.
