SPEAKER SELECT
Four switches select which of the four speaker outputs A , B, C or SUB are heard
(10) .
Each switch can be operated individually or simultaneously and in any combination
and is perfect for performing A/B comparisons between various monitor setups. As
the switches do not toggle between outputs when doing A/B comparisons both of
those switches should be pressed at the same time i.e. to compare speakers A
and C, with A active press both the A and C switches to swap the output to C active,
and then again to return to the previous setting - this method can be used between
all four outputs if required.
An additional benefit is derived when using a sub-bass. If the sub-bass is attached
to the SUB/MONO output on the rear of the MC3.1, outputs A and B could deliver the
higher frequencies and allow for A/B (or in this case A+Sub/B+Sub) comparisons
between the two monitor setups by pressing the A and B switches simultaneously
and leaving SUB always active. In addition, a full frequency range monitor could be
attached to C, so, with the C switch active SUB should be disengaged.
MIX CHECKING
The Mix Checking section allows the engineer to test various aspects of the mix
without having to alter the signal earlier in the chain and potentially effect the
recording, and is a very thorough and versatile checking tool. The switches are
especially useful when used in conjunction with each other.
Phase Reverse : Inverts the polarity of the signal on the Left Channel and is used
primarily to outline any phase problems that may be occurring in the mix/recording
such as phase cancellation, or an unbalanced stereo signal. As the switch is
toggled any phase issues will become more apparent and easier to identify.
Mono : With the switch active both Left and Right stereo signals are combined into
a single mono signal.
It is necessary when testing the audio to not only listen to the signal in stereo but
also in mono. It helps to outline problems in the mix, but also when testing for use
on non-standard applications such as for broadcast or mobile phone.
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.
Mute: Cuts the level of both channels and is 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
Mute does not affect the headphones (6a, 6b) in the same way as it does
the speakers (10) . 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.
CUT
Left Cut (5a) : Mutes the Left channel signal allowing only the right signal to be
heard,
Right Cut (5b) : Mutes the Right channel signal allowing only the left signal to be
heard,
