GENERAL

The Shure Model M677 is a transistorized, six-input

accessory mixer designed for use with such products

as the Shure M67 and M68 Series Microphone Mixers,

SE30 Gated

Compressor/Mixer, and M63 AUDIO

MASTER@. When used with either the M67 or M68, it

provides a low-cost and convenient means of adding

six additional input channels (10 total). When used

with the

SE30, it converts the three-input mixer system

to a nine-input system for applications such as tele-

vision broadcasting. For instance, when used with the

M63, the combination provides a six-channel mixer

with extremely flexible equalization, a 600-ohm line

output, a VU meter, and a headphone monitor.

The M677 is designed to connect to and operate

from the 28-30 Vdc output of the Shure mixer product

with which it will be used, or from the Shure

A67B

Battery Power Supply. When this external power sup-

ply is used, the M677's high- or low-impedance micro-

phone-level output allows it to be used with virtually

any audio equipment having a microphone input (audio

tape recorder, video recorder, PA system, etc.).
