Volume
Volume can be set to an absolute value or incremented/decremented in single steps. Volume can be adjusted in the range 0-100%. A setting of 80 represents 0dB (unity gain) with reference to the volume of the input signal. Each step adjustment in the volume represents a 1dB change (79=-1dB, 78=-2dB, 100=+20dB).

SetVolume
The SetVolume action provides a means of setting the Volume to a specific value. The minimum value that can be applied is zero. The maximum value that can be applied is determined by the VolumeMax and VolumeLimit settings. If an attempt is made to set the Volume above VolumeMax, an error will be reported. If an attempt is made to set the Volume above VolumeLimit, the Volume will be set to the VolumLimit value and no error will be repoprted.
Volume Inc
The VolumeInc action provides a means of increasing the Volume by 1.
Volume Dec
The VolumeDec action provides a means of decreasing the Volume by 1.
VolumeLimit
The VolumeLimit action reports the current VolumeLimit setting.
Balance
The Balance action reports the current Balance setting.
SetBalance
The SetBalance action provides a means of setting the Balance to a specific value.
BalanceInc
The BalanceInc action provides a means of increasing the Balance by 1.
BalanceDec
The BalanceDec action provides a means of decreasing the Balance by 1.
Fade
The Fade action reports the current Fade setting of the product.
SetFade
The SetFade action provides a means of setting the Fade to a specific value.
FadeInc
The FadeIncaction provides a means of increasing the Fade by 1.
FadeDec
The FadeDec action provides a means of decreasing the Fade by 1.
Mute
The Mute action reports the current Mute state of the product.
SetMute
The SetMute action provides a means of setting the Mute state.
Characteristics
