3 PROTECTION SYSTEM
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.
