get or set left/right output crossover filter type: xomtype
get or set subwoofer output crossover filter type: xostype
The value indicates the specified output's crossover filter type and is an unsigned integer value between 0 and 3.
0 = none (crossover disabled)
1 = Butterworth
2 = Linkwitz-Riley
3 = Bessel
Examples:
=sxomtype:1! set L/R output crossover to use a Butterworth filter
=sxostype:2! set sub output crossover to use a Linkwitz-Riley filter
get or set left/right output crossover frequency: xomf
get or set subwoofer output crossover frequency: xosf
The value indicates the edge frequency, in Hz, for the specified output's crossover and is an unsigned integer value
between 20 and 20000.
Examples:
=sxomf:180! set L/R output crossover frequency to 180 Hz
=sxosf:200! set sub output crossover frequency to 200 Hz
get or set output crossover high-pass filter enable: xohpf
The value indicates whether the output crossover high-pass filter is enabled, and is an unsigned integer value
between 0 and 1.
0 = 40 Hz high-pass filter off
1 = 40 Hz high-pass filter on
Example:
=sxohpf:1! turn on output crossover high-pass filter
get or set left/right output speaker offset: spmoff
get or set subwoofer output speaker offset: spsoff
The value indicates the audio level offset of the specified speaker output, in ½ dB steps, and is an integer between
-128 and 48 (-64.0 dB to +24.0 dB). A volume of -64.0 dB mutes the output. Adjustment of these values allows the
relative output level of the left/right and subwoofer speakers to be balanced.
Example:
=sspmoff:-20! set left/right speaker offset to -10.0 dB
=sspsoff:7! set subwoofer speaker offset to +3.5 dB
