Pre-order

8 user amplifier settings (Manufacturer's Presets: Speaker presets for Yamaha passive speakers).

Protection circuit

Load protection

• POWER button: Turns on/off; mutes.
• Output voltage protection: Overvoltage regulator, user-configurable power and speaker presets.
• DC error: Power off (NO automatic recovery).

Protection amplifier

Thermal: Output limit (Automatic recovery) → Mute (Automatic recovery); Overcurrent: Output mute (Automatic recovery); Overvoltage: Output limit (Automatic recovery); Built-in power limit: Output limit (Automatic recovery)

Power supply protection

• Temperature: Output limiting device (Automatic recovery) → Power supply shuts off.
• Overvoltage: shuts off the power; Overcurrent: shuts off the power supply.
