All amplifiers feature a bridgeable four-channel, Class D architecture, which allows them to be utilized in multiple system configurations with minimal space displacement. The 400.D Marine is rated at 55 watts RMS per channel at four ohms and is bridgeable down to two channels. The larger 800.4D Marine 4Ω is measured at 110 watts per channel at four ohms, jumping to 200 watts per channel at two ohms. Its counterpart is the 800.4D Marine 2Ω, which rates 61 watts per channel at four ohms, but can handle a one-ohm load over four channels or a two-ohm load at two or four channels.
Each amplifier features stainless-steel RCA inputs with preset high-/low-pass crossovers and gains for each pair. They are protected by conformal-coated circuit boards, stainless-steel hardware and seals around knobs and openings to prevent internal moisture.
“In talking with our dealers, we’ve found that they like to use our amplifiers in off-road and marine applications because of their size and power but worry about their longevity when exposed to the elements,” said Diogo Ianaconi, CEO of SounDigital USA. “Our new marine amplifiers solve this problem. They feature the same compact size, flexibility and generous power of our car line, but are specially designed to withstand heat, moisture and the rigors of rough roads or rough waves.”
All amplifiers are shipping in time for boating season and will be on display at the second KnowledgeFest event of the year at the Indianapolis Convention Center, March 16-18.
