Description
This parameter sets the bandwidth (in octaves) of the specified parametric equalizer band. In the case of
peaking filters, this is the bandwidth at which the gain is half the peak gain (in dB). For notch filters, this is
the 3 dB bandwidth. For all-pass filters, this is the bandwidth at which the phase shift is +/- 90 degrees. For
conference link physical channels, the band index must be between 1 and 5. For all other physical channels,
the band index must be between 1 and 10.
