Output Processing
Each output can receive signals from either the matrix,
the pink noise generator, the tone generator, or from the
master unit DANI source (if it is operating in a multi-unit
"stacked" configuration).
Output Source Select
The digital matrix delivers the audio signals used in
normal operation. The pink noise source can be used
for sound masking during operation, and for equalization
during setup. The
tone generator is used for level
adjustments and signal routing diagnostics.
The Master/Slave switch selects whether the audio
signal at the output channel will come from the unit
itself, or from the master unit
DANI (digital audio net-
work interface) source. When the unit is operating as a
slave, the signal will come from the DANI source and
any adjustments made on the output of the slave unit
will have no effect.
Details of the signal processing stages are explained in the
Online Help available after installing the software.
Mic/line Output Channels
Some outputs include an attenuator to reduce the
output level from line to mic level. The passive attenua-
tor does not change the signal to noise ratio of the
signal, but simply applies 40 dB of attenuation to reduce
the signal level.

NOTE: certain output channels
provide an attenuator to reduce
the signal to microphone level.
IMPORTANT:
Even though the output level adjustment provides up to
70 dB of attenuation, a line level output should not be
used to deliver a mic level signal - doing so will cause
the signal to noise ratio to be reduced by 40 dB. Always
use a mic/line switchable output for mic level signals.
