INPUTS

ANALOGUE

The MC3.1 has four analogue inputs comprising I/P1 & I/P2 - both balanced Neutrik

XLR/jack combi (combining a 3 pole XLR receptacle and ¼" phone jack in one XLR

housing), I/P3 - stereo RCA’s, and also AUX. - a 3.5mm stereo jack found on the

front panel (see & ‘Audio Connections’) .

DIGITAL

In addition to the four analogue inputs the MC3.1 has a combined AES & SPDIF

Digital input (upto 192kHz) via a Neutrik XLR (AES)/jack(SPDIF) combi.

The AES is designed to be used with standard 100 ohm balanced microphone

cable with a recommended maximum length of 20m. Having many short cables

joined together is not advisable as each connector can cause undesirable signal

reflections.

The SPDIF is via 75 ohm cable with a 1/4” jack, where the data conforms to the

Sony

Phillips Digital InterFace format. Because this connector only provides an

unbalanced termination, the recommended maximum length for this cable is 3

metres, even with very high quality cable. (‘Audio Connections’)

Each input is activated by the Source switches (see )

OUTPUTS

Three stereo balanced speaker outputs- A, B and C, plus a dedicated mono speaker/

sub-woofer output - SUB/MONO - are found on the rear of the unit, all in the form of

Neutrik 3 pin XLR’s. Each of these outputs has an individual Left/Right/Mono trim

potentiometer on the underside of the unit to enable easy and accurate monitor

level/room matching throughout (see ‘Monitor Calibration’).

Each output is activated by the Speakers switches (see ) - and can be activated

individually or simultaneously and in any configuration.

CUE O/P

The CUE mix is usually sent to a headphone amplifier to provide for the artist with

audio whilst recording. The MC3.1’s dedicated CUE output is located on the rear,

comprising two dual L/R 1/4” mono jacks. The mix is derived from the Cue Source

Select ( ) and the volume is controlled by the Cue Level ( ). When talkback is

active it is mixed into the CUE output.

TALKBACK

A TALKBACK OUTPUT, EXTERNAL FOOTSWITCH and EXTERNAL MICROPHONE

connectors can be found on the rear panel, in the form of ¼" jacks.

EXTERNAL MICROPHONE: An external microphone can be connected to provide a

more convenient location for the talkback. It is amplified by the inbuilt preamp

circuitry with the volume level controlled via the Talkback Volume knob ( ),

however, phantom power is not supplied so a dynamic microphone should be

used. To operate set the EXT MIC switch ( ) to active - this will bypass the MC3.1

onboard mic.
