MC7.1
- Surround Monitor Controller
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. 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 recommended that you turn the volume control down to a lower level before
turning the MC7.1 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.
DIM All
: With the switch active the output level is attenuated by 20dB. It enables you
to lower the volume without adjusting any of the settings.
MUTE All
: Cuts both channels (especially useful in an emergency). If Left Cut and
Right Cut are both active it is just the same as Mute being active.
Note that
Cut/Mute
does not affect the headphones in the same way as it does the
speakers. With the
Mute
switch active the headphones will still pass audio in just
the same way as if it was off, they are not affected. This allows for someone to edit
audio using headphones whilst a conversation is occurring in the control room, for
example.
TALKBACK
The MC7.1 has a dedicated talkback function including inbuilt microphone, external
microphone port, gain level control and external footswitch connector.
External Mic Switch
: When active disengages the inbuilt front panel microphone
and routes the operator’s voice through an external microphone (not supplied),
which is plugged into the rear panel
(see 13)
.
Talkback Active Switch
: W hen active engages either the inbuilt or external
microphone and routes the operator’s voice through the headphones and also to
the dedicated talkback output jack on the rear of the unit. The switch is non-latching
and so must be held in to be active. If preferred a footswitch can be connected at
the rear that does the same job
(see 13)
.
TalkBack Microphone
.
An electret condenser microphone as been incorporated
into the MC7.1 and is located below the Talkback Active switch on the front panel.
The talkback microphone level is found above in the
Levels
section
(4)
Activating the Talkback automatically engages the Dim switch (i.e. attenuates the
volume by 20dB) for the headphones
(4b)
and also the speaker outputs
(12)
making
it possible for the artist to clearly hear the instruction.
