NOTE:
SpkrPwr maximum output depends on the amplifier and the output configuration you select. The maximum for separate
channels is 1250 W, a single combined channel (ABCD or AB+CD) can be up to 5000 W depending on the amplifier.

Type
- the Auto Limiter Type is a protection level and its values are, Mild, Medium and Aggressive. This Type parameter, along with the Power Rating
and Impedance drive an algorithm designed to maximize the performance of your loudspeakers. They set the RMS and Peak threshold values as well
as their attack and release setting.
SpkrPwr
- if a single speaker is being driven, the SpkrPwr should be the continuous power rating of that loudspeaker. If multiple speakers are being
driven this value should be the combined power rating for the load.
SpkrImp
- if a single speaker is being driven, the SpkrImp should be the nominal impedance of that loudspeaker. If multiple speakers are being
driven this value should be the combined impedance for the load.
