Remote Configuration
Routing & Processing Pairs Web Page
Use the Routing & Processing Pairs web pages ( Figure 25 on page 41 for
Pair 1 and Pair 2 and Figure 26 on page 42 for Pair 3 and Pair 4) for the fol-
lowing:
• Input Channel Selection – name assigned on the I/O Config web page.
• Processing – set the output processing for each channel (A and B) for
each audio pair (Pair 1 to 4) with the Processing pulldown to one of the
following output conditions:
• A - selects the audio present on A as the channel output.
• -A - inverts the audio present on A as the channel output.
• B - selects the audio present on B as the channel output.
• -B - inverts the audio present on B as the channel output.
• A + B - audio present on A and B are added together as the channel
output.
• -(A + B) - audio present on A and B are added together then
inverted as the channel output.
• A - B - audio present on B is subtracted from audio on A as the
channel output.
• - (A-B) - audio present on B is subtracted from audio on A then
inverted as the channel output.
• 1 kHz - places a 1 kHz (at -20 dBFS) tone on the channel output.
• 400 Hz - places a 400 Hz (at -20dBFS) test tone on the channel
output.
• Silence - forces the channel output to silence.
• ID - identifies Channels A and B with a 1 kHz tone at a -20dBFS
level that switches between Channel A and Channel B with a
repeating cadence of 1 second on Channel A (left) followed by a 3
second tone on Channel B. Each pair from 1-4 is indicated by that
number of bursts of 400 Hz at an 8 Hz rate when the 1 kHz tone
starts on a new channel.
Note An output processing mode cannot be selected on a channel with Non-PCM
audio and processing will be forced to bypass as shown in
Figure 25 on
page 41 .
