5-Channel Class D Marine System Amplifier, 75 W x 4 @ 4 Ω + 300 W x 1 @ 2 Ω - 14.4V
The M700/5 is ideal for a complete audiophile-grade, subwoofer + four satellite system, and it fits comfortably in just about any boat's weather-tight compartments. With this incredible little amplifier, you can drive two pairs of quality component speaker systems with plenty of clean power (75 W x 4 @ 4 Ω), while also delivering a stout 300 W of power to a subwoofer system. The breakthrough that makes this much power possible in such a small chassis is our NexD™ switching design.
The M700/5 includes a 12 dB / octave high-pass filter for one main channel pair, a 12 dB octave high-pass or bandpass filter for the other main channel pair, plus a variable slope low-pass filter for its subwoofer channel. All three filters offer continuously variable cutoff frequency selection from 50-500 Hz. This amplifier's filters can also be configured as a true 3-way crossover, with a low-pass filter for the subwoofer channel, a bandpass filter on Ch. 3 & 4, and a high-pass filter on Ch. 1 & 2. An "x10" multiplier switch on the Ch. 1 & 2 high-pass filter allows its cutoff frequency to be adjusted from 50-500 Hz or 500-5000 Hz. With the addition of an HD-RLC remote level control (sold separately), the amplifier's subwoofer channel level or overall level can be directly controlled from a remote location.
This marine amplifier features white and gray powder-coat finishes, a gasketed cover for the controls and stainless steel hardware for durability in the marine environment.
