China Wholesale 4 Channels Amplifier Factory – 800W pro audio power amplifier 2 channels 2U amplifier – Lingjie
China Wholesale 4 Channels Amplifier Factory – 800W pro audio power amplifier 2 channels 2U amplifier – Lingjie Detail:
LA series amplifier uses a class H amplifier circuit design, with a power utilization rate of up to 90%, which can meet the load of 2 ohms, 4 ohms, or 8 ohms, it is the best matching power amplifier for popular high-power speakers.
Using high redundancy toroidal power transformer to ensure the reliability of working performance.
Eight LED indicators show the gain, clipping, power supply and fault status of each channel.
Two balanced XLR inputs, two balanced XLR LINK outputs, using professional Speakon sockets and fixed installation common terminals.
The output power can be quickly converted from low power to high power within one millionth of a second, ensuring that the output power is always accurately output according to the needs of the music program.
Power amplifier internal protection circuit is powerful: output current limit, DC protection, overheating protection, short circuit protection.
