from eighty hertz and below are cut from the incoming signal. But never press the switch when in music or bass
musical instrument application or the plump bass of music, or musical instrument will disappear.
L/R Assign Switch
This L/R button assigns the signal coming through the channel to the stereo bus output.
Polarity Reverse Switch
This phase reverse switch is provided for each channel. This switch enables the user to invert the phase of a

cancellation when identical microphones are used in close proximity to one another. The phase reverse switch also
can compensate for different XLR connector hook-ups where pin connections have been inverted.
