Whether Cruising Through Waves

Whether cruising through waves, sand, or mud you want to hear your tunes clearly over the noise of having fun. MB Quart’s NA3-560.4 marine amplifier can send four speakers 70 watts each to keep the music playing no matter where you are. This rugged and compact amplifier utilizes a number of technologies that ensure normal operation no matter what the conditions are like over/under voltage protection, thermal slow-down (not shut-down), and current limiting on the outputs to protect speakers.

Maximum Low Voltage Signal

Q-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion.Prewired to PC Board for additional protection. Leave connector cover closed on RCA jacks that are not used. Variable electronic crossovers allow for complete control of the sound. FLUID-FETS: MB Quart output devices, FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers.

Control of Amplifier Output

Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers. Check specifications for specific frequencies for this amplifier.Class SQ: Multi-channel amplifiers utilize the unique MB Quart Class SQ topology. Matched with Q-Stasis the sonic accuracy and clarity exceeds standard Class A/B amplifiers.Nautic gloss white epoxy finish helps reject heat on the surface of the amplifier. Heavy duty heat-sink efficiently moves heat from the MOSFET where it can be cooled.

Pulse Width Modulation Power Supply

Robust marine grade MOSFET Pulse Width Modulation power supply. Allows amplifier to product efficient power without taxing the boats electrical system. Connection from amplifier are sealed and grommeted.Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel. DC SIGNAL SENSE: The DC SIGNAL SENSE switch will allow the amp to turn on when a signal is received on the RCA inputs, so an amplifier remote turn on wire is not needed to turn on the amplifier. This feature can also be turned off.
