Page: 12 / 27

[1] Component tolerance dependent.
Table 2.
[2] Continuous power, one channel driven or peak power both channels driven.
(Thermal protection may occur at high continuous power).
Power in watts (EIA 1kHz,1% THD).
Table 3.
MLS™ positions can be different for each channel and a variety of
combinations can be achieved see Table 3.
The way to find the best MLS™ position for your application is by
experimentation using table 3 for initial starting positions. The amplifier is
very well protected (even down to 0.3 ohms).
The MA2.8 amplifier is a power converter and when you select MLS™
positions you are allocating a portion of power from 3000 watts.
