The M700/5 is ideal for a complete audiophile-grade, subwoofer + 4 satellite system and it fits comfortably in just about any boat 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 at 4 Ohm), 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 1 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 filters can also be configured as a true 3-way crossover, with a low-pass filter for the subwoofer channel, a bandpass filter on channel 3 and 4 and a high-pass filter on channel 1 and 2. An x10 multiplier switch on the channel 1 and 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 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.
