CAUTION
Applying voltages above the specifications given in

permanent damage to the hardware.
NOTE:
The length of power supply cable must be minimized. Increasing length of PSU cable is
equal to increasing the distortion for the amplifier at high output levels and low frequencies.

Speaker Connection
CAUTION
Both positive and negative speaker outputs are floating and cannot be
connected to ground (e.g. through an oscilloscope).

Output Configuration BTL and PBTL
When changing mode e.g. from BTL to PBTL, make sure that RESET switch SW3 is activated before
changing the state of mode switches SW1 and SW2. Switch SW1 and SW2 has to be synchronized in
state BTL or PBTL.
