dio, remote, or sound reinforcement use, and as an add-on

mixer for expanding existing facilities. It is also ideally suited

for use with audio and video tape recorders to provide multi-

ple microphone inputs.

Features:

S Wide, flat frequency response and extremely low dis-

tortion up to +18 dBm output

S Extremely low noise and RF susceptibility

Four switchable microphone- or line-level balanced-line

inputs with individual gain controls and low-frequency

rolloff switches. MUMETAL shielding on input transform-

ers

S Feedback-type input gain controls for maximum clip-

ping levels and dynamic range

S Output switchable for line or microphone level

S Built-in switchable peak limiter cuts output overload

distortion, adapts to power supply voltage

S LED indicator shows limiter operation or overload with

limiter defeated

S Externally adjustable limiter threshold (–4 to +18 dBm)

S VU meter calibrated for +4 and +8 dBm with range

switch. Illuminated with ac operation

S Ac or built-in battery operation. Noiseless automatic

switchover to battery in case of ac line failure. Battery

test without program interruption

S Front-panel headphone level control and monitor jack

drives almost any stereo or mono headphones; output

can be additional unbalanced line feed to drive a tape

recorder or power amplifier

S Direct mix bus for stacking units

S Automatic muting prevents speaker damage during

turn-on and -off

S Low distortion, high-stability tone oscillator for line test

and level checks

S All connections phased. Line output terminals phase-

indicated

S Compact and lightweight, with rugged, abrasion-resis-

tant case

S Internally selectable 120 or 240 Vac, 50/60 Hz opera-

tion

S Underwriters’ Laboratories Listed and Canadian Stan-

dards Association listed as Certified
