音量模块vol3

音量模块vol3 Channels: Channel Function 1 while channel is on, ramps volume channels 1 and 2 up (increase) //1 ON 1,2路同时增加 2 while channel is on, ramps volume channels 1 and 2 down (decrease) //2 ON 1,2路同时减少 3 while channel is on, volume channels 1 and 2 are muted (lowest) //3 ON 1,2路同时静音,通道关闭后恢复之前水平 volume), and when channel is turned off volume levels are restored to previous levels 4 while channel is on, ramps volume channel 1 up //4 ON 1路增加 5 while channel is on, ramps volume channel 1 down //5 ON 1路减少 6 while channel is on, volume channel 1 is muted (lowest //6 ON 1路静 音,通道关闭后恢复之前水平 volume), and when channel is turned off volume level is restored 7 while channel is on, ramps volume channel 2 up //7 ON 2路增加 8 while channel is on, ramps volume channel 2 down //8 ON 2路增加 9 while channel is on, volume channel 2 is muted (lowest //9 ON 2路静 音,通道关闭后恢复之前水平 volume), and when channel is turned off volume level is restored 10 while channel is on, ramps volume channel 3 up //10 ON 3路增加 11 while channel is on, ramps volume channel 3 down //11 ON 3路减少 12 while channel is on, volume channel 3 is muted (lowest //12 ON 3路 静音,通道关闭后恢复之前水平 volume), and when channel is turned off volume level is restored Note: Ramping a volume channel while the mute channel is on will //处在静 音的形式下是不恢复的 NOT automatically turn off the mute channel (will not restore) but the ramping will still occur and the volume change will be noticed when the mute channel is turned off. For setting ramp rates and presets, see SEND_COMMAND programming instructions for this card. For reading current volume levels and displaying bargraphs see CREATE_LEVEL and SEND_LEVEL programming instructions. Volume channels 1 through 3 use levels 1 to 3 respectively. Levels 1 = Output #1 2 = Output #2 3 = Output #3 SEND_COMMANDs: 'P

L[TR[U|D]' Sets the ramp rate of the specified channel(s) where the time is the time to ramp the full range both down to up and up to down or optionally just down to up or just up to down Example of usage: 'P0R50' sets ramp rate of channels 1 and 2 to 5 seconds full range from down to up and up to down 'P3R50D' sets ramp rate of channel 3 to 5 seconds full range from up to down only 'P1=P2' sets channel 1 level to the same as channel 2 'P1=P3' sets channel 1 level to the same as channel 3 'P2=P1' sets channel 2 level to the same as channel 1 'P2=P3' sets channel 2 level to the same as channel 3 'P3=P1' sets channel 3 level to the same as channel 1 'P3=P2' sets channel 3 level to the same as channel 2 Note: Cannot use 'P0' with these commands.
