1. As a stereo amplifier connected with a speaker system of coaxial, 2-way or 3-way type.
Two speaker systems can be connected in parallel, one front and one rear system.
2. As a subwoofer amplifier with max two 4 ohm subwoofers in mono bridge mode. The built-in lowpass
crossover is used. (Connect to L+ and R-).
DLS A2 has an inbuilt adjustable lowpass filter that should be set to approx. 70-80 Hz.

If you have problems with the
mid bass driver "reaching the
bottom" (the voice coil
touches the bottom pole
plate) at high volumes, use
the HP-filter to avoid this with
a setting at 50 - 80 Hz or
higher. Make your own tests.
