The MS-DA41400 is a 4 Channel, Class-D Hi-Fi amplifier. The key benefit of a Class-D amplifier is low battery drain with a high output, making this the perfect amplifier for the outdoor environment. The MS-DA41400 incorporates heat-tempered and conformal coated PCBs for maximum product life, plus the amplifier chassis is a heat sink, to reduce component core temperature and increase efficiency.
