LQSC AMPLIFIER MODULE Class D Stereo TPA3221 2x85W 4 Ohm
This LQSC lass D stereo amplifier module features a TPA3221 chip, capable of delivering 2x85 power at 4 Ohm with 92% efficiency, while guaranteeing clear, detailed reproduction with sub-1% total harmonic distortion. This module also incorporates its own volume control. The amplification chip is topped by a heatsink to efficiently dissipate the heat generated. The module also benefits from a complete protection circuit against overvoltage, undervoltage, overcurrent, overtemperature and short-circuit.
On the connector side, input is either via a 3.5mm jack or a 2.54mm 3-pin XH connector. Output is via a screw terminal block.
