The way to find the best MLS
TM
position for your application is by experimentation. The
amplifier is very well protected (even down to 0.3 ohms) but when time is of the essence,
stick to the fixed positions.
The thing to remember with the LA 24 that it is a power converter and when you select
MLS
TM
positions you are allocating a portion of the total power available.
