DESCRIPTIONS：

The D7377 is a new technology class AB car

radio amplifier able to work either in DUAL

BRIDGE or QUAD SINGLE ENDED configuration.

The exclusive fully complementary structure of the

output stage and the internally fixed gain guarantees

the highest possible power performances with

extremely reduced component count. The on-board

clip detector simplifies gain compression operation. The fault diagnostics makes it

possible to detect mistakes during car radio set assembly and wiring in the car.
