1.3.23 Set Output High-pass Filter
The Set Output High-pass Filter command configures the high-pass filter (HPF) on the stereo
output. The HPF can be turned off or set to a frequency between 50 and 150 Hz.
The following command sets the Output HPF to 80 Hz:
SOHPF 80<CR>
Response:
ACK SOHPF 80<CR>
The following command turns the Output HPF off:
SOHPF 0<CR>
Response:
ACK SOHPF 0<CR>
1.3.24 Get Output High-pass Filter
The Get Output High-pass Filter command returns the setting for the high-pass filter (HPF) on
the stereo output.
The following command returns the Output HPF setting:
GOHPF<CR>
Response:
ACK GOHPF 0<CR>
1.3.25 Set Test Mode
The Set Test Mode command allows various test modes to be activated. These test modes
are useful during system configuration and installation. All test modes are mutually exclu-
sive. The following test modes are available.
0 = Test mode off
Turns test mode off, returning the device to normal operation.
1 = Demo mode
Turns on demo mode (same “DEMO ON” command). See DEMO command for details.
2 = TS Port Test mode
Turns on TS Port Test mode. In TS Port Test mode, each TS Port’s LEDs are turned on in the
“Red” state. Each touch of the TS Port’s touch switch causes the LEDs to cycle red/green/
blue/red/etc. This provides an easy way to test the TS Port switches and LEDs without requir-
ing external equipment.
3 = VU Meter mode
Turns on VU Meter mode. In VU Meter mode, each TS Port’s LEDs are used as a “signal level”
indicator, allowing the microphone gain to be adjusted so the signal is at an appropriate
level.
off = below -40 dBFS (no meaningful signal present)
green = -40 to -6 dBFS (signal present)
yellow = -6 to -3 dBFS (signal at optimal input level; should be yellow
during loud input peaks)
red = above -3 dBFS (signal close to or at clipping level; avoid red
for best audio performance)
4 = Latency Test mode
Turns on Latency Test mode. Latency Test mode measures the time delay between a TS Port
touch switch state change message being sent and a LED state change message arriving.
