    11-1 11-1 Circuit details: Amplifier: Attention: In the POWER 2001 module the power amplifier IC AN7591 is used as a bridge-amplifier. Any connection from output to ground will destroy the outpout stages! • Via the AMP_ON control line, connected to pins 6 (Stby), the power amplifiers are switched on/off by the µP. High level (approx.
