Lab Gruppen fP 2400Q

• DC protection – Blocks infrasonic signals due to fault conditions
• VHF protection – Protects the loudspeakers from sustained (non-musical) very high frequency signals above the audible range.
• Thermal protection – Protects the amplifier from overheating. The protection warning indicators on the front panel illuminate before the protection process is initiated.
• AC protection – Shuts down the power supply if the line voltage is outside the operating voltage.
• Clip limiter – Prevents severely clipped waveforms from reaching the loudspeakers while maintaining full peak power.
