Note:
Restore Factory command will clear all ties, presets, schedule settings, and
unit name. -AP units with input volume adjustment will set input volume to 0 dB
(gain of 1) on all channels. Upon completion of this command, all LEDs on the
front panel will flash on and off.
3.2.5 Rebooting the System
To perform a system reset/reboot (same effect as cycling AC power):
Command:
FB<cr>
stands for Firmware Boot
Response:
Are you sure (Y,N)?<cr>
Note: You have 5 seconds to press Y, or the command is cancelled.
3.2.6 Setting Outputs to PRO Audio Line Levels
The matrix’s outputs can be set for Pro-audio line levels of (+4dBu). Setting the
pro output affects all the outputs simultaneously and has no bearing on the audio
input volume adjustment procedure.
To set audio output line-level mode:
Command:
LPn<cr>
stands for Line level Pro n = 0,1 (0 consumer, 1 pro)
If the parameter n is missing, then the unit will respond with the current setting.
R
esponse:
LPn<cr>
3.2.7 To Adjust Audio Input Gain and Attenuation
This command is valid for units with Pro Audio (-AP). The wildcard character ‘*’
is acceptable for input audio channel. In addition, this command can be used to
monitor or query the audio input gain. Omitting the gain value will result in a
response of the current setting for that output
To set the audio gain (default value is 10 that corresponds to a gain of 0 db):
Command:
AGn, g<cr>
stands for Audio Gain n = input channel (could be *), g=
value (0 to 16 where 0 is mute & 16 is +6dB see figure 14 X-axis 0 to 16)-
Response:
AGn, g<cr>
Note: if you enter AGn<cr> then you will get the response as above for the n
input
