CMC7
- Surround Monitor Controller
WARNING:
It is recommended that you turn the volume control down to a lower level before
turning the CMC7 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.
OUTPUT
Mute:
Cuts the volume of all channels (especially useful in an emergency). Note
that
Mute
affects the headphones in the same way as it does the speakers.
Dim
: With the switch active the output level is attenuated by 20dB’s. It enables you
to lower the volume without adjusting any of the settings.
STEREO MIX
Active:
W hen active mixes down all eight channels to their relevant position within
the stereo mix and outputs the signal via the Left and Right speakers and also the
Sub signal to the LFE of the surround setup.
SUB:
Toggles the Sub (LFE) on and off to hear the stereo mix through the L and R
speakers only. Note that this switch only functions when the stereo mix is active.
HEADPHONE LEVEL
The CMC7 has a dedicated headphone output, via 1/4” TRS jack on the rear face
(7)
, with individual headphone amplifier and level trim
(4)
on the top face. The
headphone operates in stereo, with all eight channels mixed down to their relevant
position within the stereo mix.
Note that the headphone level control is a trim that works simultaneously with the
Master Volume
(1)
to adjust the volume of the headphones so that this output can
suit all types of headphones, from professional studio grade to consumer. It
responds to Dim and Mute
(2)
in just the same way as the speaker outputs do.
The headphone output trim has no bearing on the volume of the main speaker
outputs
(6)
, however, as the headphone amplifier is of such a high quality the
headphone output could be used as a source for a second set of stereo monitors,
should they be required, the trim control being used for speaker level matching.
Warning:
It is advisable to unplug the headphones before switching the CMC7 on or off.
It is also recommended that you turn the headphone level down before inserting
the jack, and turn it up to your desired listening level - these measures will not
only prevent your ears from being damaged but also the headphone’s drivers.
Also, note that these are high quality circuits and have been designed for
professional headphones, so care must be taken to lower the volume using
the headphone level control when using lower standard, consumer quality
headphones as damage could occur.
