Sonodyne AM21P - Manual (Page 13)

Command: Channel Input Cross Mix Level (PCML)
This command is used to get/set the level of an input to an amplifier channel.
%PCML:xyzz<CR>
Where x is output channel to select (between 1 and 4) and y is the input channel (between 1 and 4).
For volume parameters, the zz section of the command can range between 0x00 (muted) and 0xE1
(225 = +12dB of gain). This allows half dB steps, where 1 = -100dB, C9 (201) = 0dB and E1 (225)
= 12dB.
e.g. %PCML:11C9<CR> sets the level routed from input 1 to output channel 1 to unity.
e.g. %PCML:42BD<CR> sets the level routed from input 2 to output channel 4 to -6dB.
When the value has been changed (from either GUI or external comms), or the current value has
been requested, the amplifier will send:
%PCML=xyzz<CR> where x, y and zz are as per above.
To request the current value of a cross-mix level, use:
%PCML:xy??<CR>
Command: Channel Input Cross Mix Mute (PCMM)
This command is used to get/set the mute state of an input to an amplifier channel.
%PCMM:xyzz<CR>
Where x is output channel to select (between 1 and 4) and y is the input channel (between 1 and 4).
For mute parameters, the zz section of the command can range between 00 (mute off) and 01
(mute on).
e.g. %PCMM:1100<CR> sets the mute state of input 1 to output channel 1 to unmuted.
e.g. %PCMM:4201<CR> sets the mute state of input 2 to output channel 4 to muted.
When the value has been changed (from either GUI or external comms), or the current value has
been requested, the amplifier will send:
%PCMM=xyzz<CR> where x, y and zz are as per above.
To request the current value of a cross-mix mute state, use:
%PCMM:xy??<CR>
