STEREO CONTROL

This section allows the engineer to test various
aspects of the stereo mix without having to alter the
signal prior to the MC7.1 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.

Band Solo: 

The three switches allow the engineer to

easily solo the 

Low, Mid

 and 

High

 frequencies of the

stereo mix. This helps to pinpoint problems occurring
at particularly frequencies or to check for unwanted
signal artefacts that may bleed into each band, for
example.

Each switch can be used in conjunction with each other and in any order. However,
it is not recommended that all three Band Solo switches are active simultaneously
as this will effect the signal at the crossover frequencies. For this very reason the
MC7.1 has been designed so that with no Band Solo switches active the entire
Band Solo circuit is completely relay bypassed.

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.

Left/Right Swap: 

Swaps the Left and Right channels of the stereo signal. It is

particularly useful when checking for shifts in the stereo balance of the mix.

Under the 

Cut

 heading two switches have been incorporated - 

Left Cut 

and

 

Right

Cut

.

Left Cut:

 Mutes the Left channel signal allowing only the right signal to be heard,

Right Cut:

 Mutes the Right channel signal allowing only the left signal to be heard.

Note that when activating 

Left 

or

 Right Cut

 whilst using headphones the signal is

not 100% panned one way or the other - i.e. the signal centre moves to the side but
is not completely removed from the opposite ear of the headphone - this is so that
the 

Left/Right Cut

 sounds a little more natural, after all, if listening through speakers

with only the left speaker active some of the signal well reach the right ear a few
milliseconds later.

With 

Left Cut

 and 

Right Cut

 are both active it mutes both stereo channels in both

the headphones and speakers.
