Description

Class D 3x400W Amplifier

Sure Electronics - AA-AB35311

This multi-channel audio amplifier board employs T-AMP technology and is capable of delivering 400W per channel @ 3 Ohm. Sure Electronics T-AMP technology not only achieves high efficiency up to 95% but also delivers the best sound possible from a Class-D board for your audio project. A low-noise cooling fan is mounted atop the robust heatsink for a drastic reduction for the system temperature and ease of cooling. Over temperature protection, over current protection and over/under voltage protection are also included to ensure its reliability.
