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
, as described on page 36. If this is not possible, the system can
be calibrated 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 (
E
X2TSTA
}
) or
Dolby Noise (
E
X1TSTA
}
).
2.
Send the SIS command that mutes all output channels (1Z).
3.
Send the SIS command to unmute each output channel individually (
X@
*0Z where
X@
represents the number of the output channel).
4.
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.
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 (
E
X0TSTA
}
)
and the SIS command that unmutes all channels (0Z).
Using External Source test signals
1.
Select the input that provides the test signal.
2.
Change the listening mode for the source format of the input signal to “Mono to All,”
using
in one of the following ways:
a.
Configure the user mode settings to auto select “Mono to All” as the format of the
input signal. 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 EU
X!
*4*8SSP
}
to change the option 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 (1Z).
6.
Send the SIS command to unmute each output channel individually (
X@
*0Z where
X@
represents the number of the output channel).
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.
9.
To end the session, send the SIS command that turns off the test source (
E
X0TSTA
}
)
and the SIS command that unmutes all channels (0Z).
