from Shure Brothers Inc. as Shure Part

mating three-pin professional female connector (to

mate with MIC OUTPUT) may be ordered directly from

Shure Brothers Inc. as Shure Part

RK120P.

For microphone- or line-level balanced-line connec-

tions to these inputs and output, use two-conductor

shielded cable with the shield to pin 1, and two "hot"

leads to pins 2 and 3. For unbalanced-line

low-imped-

ance connections, use single-conductor shielded

cable with the shield to pins 1 and 2, and the "hot"

lead to pin 3. For high-impedance microphone output

or line-level input connections (unbalanced only), use

single-conductor shielded cable with the shield to pin

1 and the "hot" lead to pin 3. See Figure 2 for illustra-

tion of these alternatives.

FIGURE 2

The MIX BUS AND AUX OUTPUT is a phono pin

jack. A 305

mm (12 in.) long interconnecting cable

(single-conductor shielded with a phono pin plug on

each end) is supplied with the

M677. Note that the

"hot" lead is connected to the phono pin plug tip and

the shield to the shell.

"Y"

connections may be made

to phono pin plugs used in the MIX BUS AND AUX

OUTPUT jack when

M677s are stacked.

OPERATION

POWER ON-OFF Switch:

Activate POWER ON-OFF

switch to turn the M677 on. Note that power supplied

by the associated Shure mixer is present at the 30 VDC

jacks whether the M677 POWER switch is on or off.

MIC/LINE Selector Switches:

Set individual channel

MICILINE switches for microphone- or line-level in-

puts as desired.

Volume Controls:

The individual volume controls for

each of the six channels are identified on the front

panel. Volume controls for individual channels not

being used should be kept at minimum setting (fully

counterclockwise). For maximum signal-to-noise ratio,

the volume controls in use should be set to the highest

position possible without incurring overload distortion.

LO-CUT Filter Switches:

Activate individual channel

LO-CUT filter switches as desired to reduce low-fre-

quency response (approximately 6 dB at 100

Hz).

Operation with Shure Mixers:

Connect the 30 VDC

power leads of the M677 to the auxiliary power output

jacks of the "master" unit (Shure M67 or M68 Micro-

phone Mixer, SE30 Gated

Compressor/Mixer, or M63

AUDIO MASTER@). Connect the M677 MIX BUS AND

AUX OUTPUT to the mix bus or aux input of the master

unit. This connection will result in a total of

10 inputs

for the M67 or M68 (the aux volume control of the M68

may be used as a submaster control for the M677 in-

puts), nine inputs for the

SE30, or six inputs (with tone

control capability) for the M63.

If a submaster function

desired for the M67 or SE30,

the M677 MIC OUTPUT connector may be connected

to a microphone input on the master unit. The channel

volume control becomes a submaster control for the

M677 output. Make certain the M677 HI-LO IMPED-

ANCE switch is set to match the microphone input of

the master unit.
