Output signal, post mic mixer, controls ( f )
The output signal processor chain, post mic mixer, makes adjustments to mixed
program and microphone audio, before it is output to the selected speakers or other
audio devices.
Delay block — The delay processor block, when inserted,
provides a means to delay the audio signal to compensate for
speaker placement in the situations where some speakers that
are delivering the same signal are much farther away than others. The delay
processor block is identical to the delay processor available on the input
and described in “Program audio input signal controls ( a )“. Delay the closer
speakers so that delivery time matches the farther speakers.
Filter block — The filter processor block, when first
inserted, provides one of four filter selections;
additional filters can be then be added. The available
filters and adding additional filters are identical to as
described on the program audio input in the filter
processor block (except that up to nine filters total can be selected for this block).
See “Program audio input signal controls ( a )“.
N Selecting “Bass & Treble Filter” inserts two separate filters.
Dynamics blocks — The dynamics processor block, when
inserted, provides one of four dynamics processors. The
available processors are identical to the processors
available on the input in the dynamics processor block
and described in “Program audio input signal controls
( a )“.
Volume control — The always-present volume control provides the same basic
audio output level adjustments that are available from the front panel (see
“Viewing and adjusting the output volume“, in chapter 3, “Operation”).
Additionally, the left and right output channels each have trim controls,
accessible in the dialog box, for separate fine adjustment with a gain
range of -6 dB to +6 dB in 0.1 dB increments. The default setting is
unity gain (0.0 dB).
N
The trim settings are not indicated in the front panel volume display.
The
Polarity
buttons, accessible in the dialog box, let you flip the polarity of
the wires connected to the audio connectors (+/tip and -/ring) to easily
correct for miswired connectors.
The
Mute
button, accessible in the dialog box, lets you silence the audio
output. This control is identical to the audio mute control available
from the front panel. When the audio output is muted, red indicators
in the block turn on.
