Roswell RMA 500.4 Amplifier

This RMA 4-channel marine amplifier uses a full range Class G/H topography that significantly improves efficiency while enhancing sound quality. All RMA amplifier PCB boards have been processed with a conformal coating for complete marine-grade protection. And don't let the compact size fool you. Class G/H amplifiers produce more power for their size than traditional designs and offer much lower distortion with higher damping factors than Class D amplifiers.
