Rockville RXM-F3 1600 Watt Marine/Boat 4 Channel Amplifier Amp+PA Microphone

<p>The RXM-F3 has a conformal coating on its PCB (printed circuit board) in order to protect against moisture . dust . chemicals . and temperature extremes. This coating protects the amplifier from the elements of the ocean. If water gets sprayed on the amplifier you will not have to worry. The exterior screws are made of stainless steel to better withstand the elements. This amplifier is fully marine-rated from start to finish.<br>One of the tricks to determine the real power of an amplifier is to multiply the fuse rating by 10 to determine the true RMS power. This formula almost always works within 20%. RXM-F3 features three 20 Amp Maxi fuses. Compare this to other amps on the market with similar fuse ratings and you'll see that with the RXM-F3 you are getting your money's worth and then some.<br>Other features include Auto-Start Smart turn-on (This function senses when there is a signal from the head unit and automatically turns on the amplifier hence no need to run a Remote Turn-On wire) . a fully adjustable 12dB bass equalizer . 2 ch/ 4 ch input mode switch . mute and delay soft start technology . and a crossover band-pass control. The RXM-F3 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free musical playback at all levels.<br>The circuitry of this amplifier is a class A/B circuitry. Class A/B is known to have amazing sound quality. Pro audio amps usually all are class A/B. Class A/B however is not known for its efficiency. To make this amplifier more efficient we simulated a class G amplifier. Class G is technology that switches the rail voltage depending on how much power is being used. We have similar technology built into these class A/B amplifiers which make these about 65-70% efficiency which is just amazing for a class A/B amplifier.</p><p><b>Features:</b><br>Rockville RXM-F3 1600w/260w Dyno-Certified RMS 4-Channel Marine Amplifier<br>Dyno Certified RMS Power Ratings: (Certified Dyno Test / Less than 1 % THD) (Use these ratings when comparing with top brands such as Kicker .
