Fashion front panel is made of brushed aluminums alloy.
Sturdy steel case can shield the electromagnetic interference from outside.
Strong multi-protection mechanism including radiating protection, short circuit protection and switch delay protection.
4 channels output and 800w rated power of per channel
Design of optimized switching power supply makes the amplifier smaller and easy to be installed.
High quality connectors guarantee perfectly signal transmission by firming conjunction.
Suitable for large stages, pubs, KTV rooms and large conference rooms etc.
