1200 Watts RMS
USA-400
All four of these amplifiers are
based on the same circuit
board.
They use different
transformers and output
components, but they share
many similarities.
The input
section is isolated and must
receive an input ground to
function properly. A minimum
of 8 gauge wire must be used
for all power and ground
connections.
