FB-2.4KQ Low Voltage 100v Mini Switch Power Amplifier For Meeting Conference Rooms

FB-2.4KQ is the smallest powerful in FB series 4-channel power amplifier, it is 450w per channel at 8ohms load, 550w per channel at 4ohms load, and it is stable on 2.67ohms load. With the high power and Efficient cooling system , FB series ampliifers will be in all situations from installation to high performance live sound systems.

1. We use large current rectifier bridge to ensure the unobstructed supply current. Using independent shielding way in the high-voltage power part, able to reduce the interference to audio signal to the lowest level, and ensure the higher safety for electricity.
2. We use high performance audion, make the system can bear larger current, with better dynamic and safety. Each audion has to be checked strictly, ensure the consistency of amplifier and minimum distortion.
3. We use the way of mainboard power-supply for the process the audio signal, able to make the voltage more stable, clear and thick, and sounds much better. Reasonable wiring can reduce the interference between channels and input-output.
