Input channel controls.
get or set digital input volume: iv0
get or set analog input volume: iv1
The value indicates the input volume level, in ½ dB steps. The input volume is an integer between -128 and 0 (-64.0
dBFS to 0 dBFS). A volume of -64.0 dBFS mutes the input, and a volume of 0 dBFS is full volume (unity gain). The
input volume is a digital volume adjustment that occurs in the DSP.
Example:
=siv1:-41! set analog input volume to -20.5 dB
change digital input volume by specified value (valid for set only): iv0step
change analog input volume by specified value (valid for set only): iv1step
The value indicates the relative input volume adjustment, in ½ dB steps. The volume adjustment is an integer
between -12 and 12 (-6.0 dB to +6.0 dB). This command allows relative adjustment of the channel's current input
volume. When this command is used, the amplifier will respond with the new volume level, as if a “get” command
had been issued.
Examples:
=siv0step:4! increase digital input volume by 2.0 dB
=siv1step:-10! decrease analog input volume by 5.0 dB
get or set digital input mute control: imute0
get or set analog input mute control: imute1
The value indicates whether the input channel mute control is off (not muted) or on (muted), and is an unsigned
integer between 0 and 1. Changing the input mute control does not change the channel's input volume setting.
0 = channel not muted
1 = channel muted
Examples:
=simute0:1! mute digital input
=simute1:0! unmute analog input
get or set digital input enable mask : dienab
The value indicates which of the two digital inputs are enabled, and is an unsigned integer between 1 and 3. Inputs
that are not enabled will be ignored by the amplifier.
1 = only S/PDIF (coax) input enabled
2 = only TOSLINK (optical) input enabled
3 = both S/PDIF and TOSLINK inputs enabled
Example:
=sdienab:2! enable only TOSLINK (optical) input
