Chapter 5: Mono Input Channel
VeniceF
Operator Manual
Gain
This section lets you adjust the level of the mic input signal, switch on 48 volts phantom
power for the mic, attenuate the input signal by 20dB, invert the mic polarity and
enable the high pass filter on the mic input.

Item
Description
1
20dB pad switch
This pad switch provides 20dB attenuation to the input
signal, allowing for the connection of high output microphones and line level
signals without overloading the channel input amplifier. Overloads are
indicated on the meter by the red LED at the top (see “Fader and meter” on
page 41).
2
mic gain control knob
The mic gain is continuously variable from +10dB
to +60dB (-10dB to +40dB with the pad enabled). The actual value of the
gain required will depend upon the source and should ideally be set such
that peaks in level on the input should not cause the input amplifier to
overload (occasional peaks of +12dB are OK, but +18dB is too high).
3
80Hz switch
The hi pass switch inserts the 80Hz hi pass filter in the input
channel signal path before the insert point and EQ. This is commonly used
to remove handling noise from a mic, bass rumble through coupling with
the stage or any unwanted low frequency audio.
4
mic Ø switch
This is a microphone polarity switch that causes a
180-degree phase change (with respect to the input signal) to occur in the
input amplifier such that the channel signal will have opposite polarity to
the input signal.
The
mic Ø
switch is commonly needed where two microphones are used
facing each other (for example, when using a microphone on both the top
and bottom of a snare drum). Ordinarily the two microphones would be out
of phase causing cancellation when the console sums the two signals into
the output. Reversing the phase of one signal causes the microphones to
have the same phase and no cancellation.
5
48V LED and power switch
The
power
switch applies 48 volts of
phantom power to the microphone input. This is used to power condenser
microphones, direct inject boxes and other devices that require phantom
power. The
48V
LED illuminates to show that phantom power is on.
