Cable Wiring

In agreement with IEC and AES/ANSI

standards, XLR wiring convention is pin 2

Positive (hot), pin 3 Negative (cold), and

pin 1 chassis grounded and signal grounded

(to allow unbalanced operation). The XLR

case is chassis grounded.

Power ON switch and LED

Your basic, straightforward power switch.

When the switch is depressed and the

yellow LED is lit, the MC 22 is ready to go.

CHANNEL 2 controls

These duplicate the controls in Channel 1.

LINK switch

Switch this to ON when using stereo

material. This activates both Compressors

when either Channel’s signal exceeds the set

Threshold, preserving stereo imaging.

CHANNEL 1 INPUT

Choose between the balanced XLR or the

balanced/unbalanced ¼" TRS jacks, but

only use one. Inserting a ¼" TS jack will

work—however—use balanced  lines,

especially  when connecting cables over 10

feet in length. Consult SOUND SYSTEM

INTERCONNECTION on page Manual-10.

CHANNEL 1 OUTPUT

Use either the balanced XLR or the unbal-

anced ¼" TS jack. Using both types of

Outputs are permissible to drive two devices,

such as an amplifier and a recorder.

 This

device uses low impedance balanced line

drivers. 

Do not

 connect the XLR “+” or “–”

output pins to ground, as this may cause the

power supply to shut down. For unbalanced

use, leave the unused output pin (“+” or

“–”) unterminated.
