Phase and Attenuation
Phase
The Phase (
∅
) function inverts the phase of the selected signal. When the
phase of an channel is inverted against a corresponding channel, it can
cause attenuation of both channels due to phase-cancellation. This can be
caused by incorrectly wired cables or connectors. It can also be caused
improper microphone placement, especially when attempting to record in
stereo.
cause attenuation of both channels due to phase-cancellation. This can be
caused by incorrectly wired cables or connectors. It can also be caused
improper microphone placement, especially when attempting to record in
stereo.
The Phase (
∅
) function can compensate for these problems. It is also useful,
for example, when a snare drum is miked top and bottom. In this case the
bottom microphone signal should be phase inverted. The phase can be set
to normal or reverse (inverted) for the input channels and the tape and
effect returns.

The stereo input channels are always ganged together. The MIC/LINE and
TAPE channels are always set independently even when they have been
linked together in GANG mode with the PAN function.

Attenuation
The Attenuation function is used to cut the level of the selected signal by as
much as 96 dB. This attenuation is applied after the signal has been
converted to digital (or format converted in the case of a digital input).
much as 96 dB. This attenuation is applied after the signal has been
converted to digital (or format converted in the case of a digital input).
The attenuation function is repeated in the EQUALIZER display functions,
where it can be used to compensate for the gain increases caused by
boosting different frequencies.

You can also set the phase and attenuation with the VIEW display function.
Note:
You cannot invert the phase of the STEREO output channel.
Note:
The STEREO output channel attenuation is in the range of +12 dB to
–96 dB. The attenuation for all other channels is 0 dB to –96 dB.
