MC2.1 - Monit or Controller

Ta lkback L evel. The knob ad justs the gain level of the talkb ack mic rop hon e. It c an

be adjus te d to compensa t e for the distance t hat the opera t or i s from the microphone,

how loud his voice is, or the volume of the underlying music played, as well as

several other factors.

TalkBack Microphone. An electret condenser microphone as been incorporated

into the MC2.1 and is located above the Talkback Level on the front panel.

Activating the Talkback automatically engages the Dim switch (i.e. attenuates the

vo lume by 20 dB) for the headphon es and also the sp eaker outp uts m aking

it possible for the artist to clearly hear the instruction.

As well as the headphones the talkback signal is also routed to the direct talkback

output jack on the rear of the un it to be ro uted at th e en gin eers discretio n.

To operate talkback press the talkback switch and then turn the gain level up until

all those wishing to hear the operator’s voice can. Talkb ack is only active whilst the

switch is held in and will de-activate once the finger is removed.

MONITOR VOLUME

The Monitor Volume control adjusts the signal level of both stereo channels for all

speaker outputs. The Volume knob affects the volume of the monitors A (plus the

mono), B, & C only and does not have a bearing on any other output such as the

headphones or talkback jack.

Because the circuitry is active it allows for the signal level to be increased, rather

than only attenuated, making subtle problems within the mix (such as noise at low

levels, or unwanted harmonics, for example) more obvious and easier to iron out,

especially during musical passages that would normally be quiet.

The volume knob circuit design incorporates a parallelled custom quad

potentiometer, for excellent channel matching and a smooth feel, w ith a range from

Off (-infinity) to +12dB of gain.

Before you can make full effective use of the Volume control it is necessary to

calibrate the entire monitoring system (see the ‘Monitor Calibration’ section) - this

allows for accurate level control, as well as left/right balance throughout the knob’s

range. Note that the actual output levels, including the maximum output level and

the position of unity gain (0dB) around the knob, will alter depending on the

calibration of the monitors.

WARNING:

It is rec ommended that you tu rn the volu me control do wn to a lo wer level before

turning the MC2.1 off - this is to ensure that a sudden volume increase when

turning on does not damage your speakers or your hearing

In addition, do not use excessive force at either end of the volume knob - it’s

size would mean that damaging the potentiometer is possible.

POWER LED

A lit 2mm LED indicates th at the unit is switched on. To turn the MC2.1 on see the
