3 PROTECTION SYSTEM 15

3. PROTECTION SYSTEM

This amplifier uses a very complex protection system. If an error occurs, the amplifier

switches to standby or off mode and prints an error code to the display.

In this way, the protection system is able to avoid a series of potential damages to the

amplifier, but there is no reason to operate carelessly.

3.1. Errors in Power On mode:

Code Legend

17 average plate voltage too high
