Setting up Test Sources with SIS Commands

Extron recommends that the SSP 7.1 Setup and Control Software is used to calibrate
the system with the test signals, as described on page 5-12. If this is not possible, it
is possible to calibrate the system using SIS commands.

Using Pink Noise or Dolby Noise test signals

1. Send the SIS command that turns on the test source as Pink Noise (
or Dolby Noise (
2. Send the SIS command that mutes all output channels (
3. Send the SIS command to unmute each output channel individually (
where
4. The signal will be output through the unmuted channel; the user can adjust
speaker delay or output trim and hear the test noise change in real time.
5. Mute the current output and unmute the next channel, to test each output in
turn.
6. To end the session send the SIS command that turns off the test source

Using External Source test signals

1. Select the input that will supply the test signal.
2. Change the listening mode for the input signal's source format to "Mono to All",
using SIS commands (see chapter 6) in one of the following ways:
a. Configure User's Mode settings to auto select "Mono to All" as the input
signal's format. If the listening mode was changed, the source is downmixed
to mono, which is output to all available channels at equal levels.
OR
b. With a source actively playing, toggle through the mode override options to
select "To All". Enter the SIS command
to "Mono to All".
X!
is the input channel, 4 is for the "To All" Mode Override Group, and 8
selects "Mono to All".
3. Play the source audio through the selected input.
4. If the user mode was correctly set to "Mono to All" in step 2, the output should
be heard equally from all channels. If not, toggle the Mode Override button on
the front panel to "To All", to enable "Mono to All".
5. Send the SIS command that mutes all output channels (
6. Send the SIS command to unmute each output channel individually (
where
7. The signal is output through the unmuted channel; the user can adjust speaker
delay or output trim and hear the test noise change in real time.
8. Mute the current output and unmute the next channel, to test each output in
turn.
