Audio Transition Time
The time parameter, fourth parameter in a command, is used to smooth
transitions between volume levels. It may be used to minimize “pop” or sudden
noises when switching audio sources.
For Volume:
[BL,99,1,10]
This command will have a smooth transition from current volume to 99 within
10 seconds.
For Switching:
[BX,2,1,10]
This command will fade the volume in output 1 to 0 in 5 seconds, switch video
and audio from input 2 to output 1, and fade the volume back to current in 5
seconds.
For V, D, and C commands, the volume will not fade but instead delay for half
the time parameter before it switches.
B, and T commands are not affected by transition time and will be executed
immediately.
For lower volumes, the matrix switch will not wait for the time to expire, which
means switching can happen faster once the target volume is reached.
Volume Only Commands
Please check the Features section to ensure your NeoPro model has this feature.
These commands only affect analog audio. The Volume command format is:
[mL,f,n]
m
is the first letter of the model name (refer to Model Specific Features section)
L
indicates volume command mode
f
is the specific function
M0
for absolute mute
MP
for partial mute
U
to increase volume by one
D
to decrease volume by one
n
is the output number
