MB Quart NA3-600.6 6 Channel 600 Watt Marine Amplifier

MB Quart NA3-600.6 6 Channel 600 Watt Marine Amplifier

Nautic waterproof amplifier with marine connectors, and six channels. Sound contouring with onboard crossovers, bass boost, and variable input sensitivity are all hidden behind top-mounted controls. You want to be able to hear your music clearly over the din of having fun, whether you're cruising through waves, sand, or mud. The NA3-600.6 marine amplifier from MB Quart can send six speakers 50 watts RMS each, making it ideal for a system with three zones. 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.

A versatile amplifier

For example, you could set up this amplifier as a 3-channel amp and send 200 watts RMS to three tower speakers. It can power four full-range speakers with 50 watts each and a sub with 200 watts as a 5-channel amp. In 4-channel mode, it can drive two full-range speakers, a high-performance tower speaker, and a subwoofer. You can adjust the sound to match your speakers and subs using the onboard variable tone controls.

Marine Tough

Each MB Quart marine amplifier is the culmination of three decades of marine and powersports audio expertise. Conformal coating protects internal circuits from water and dirt, and stainless steel hardware resists corrosion in even the saltiest environments. MB Quart designed and tested this amplifier to withstand the most extreme conditions on and off the water.

NA3-600.6 Features:

• Marine Grade Protection / IPX Rating: Meets or exceeds IPX standards for waterproof and dustproof.
• Low Noise Preamplifier Circuit: Q-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion.
• RCA Inputs: Prewired to PC Board for additional protection. Leave connector cover closed on RCA jacks that are not used.
• High Level Inputs: See Auto-Sense Feature.
• Operation Mode: 2 / 4 / 6 Channel
• Crossover Type: Variable electronic crossovers allow for complete control of the sound.
• Electronic Equalizer: 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 / Topology: 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.
• Output Device Technology: 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.
• Heat Sink: 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.
• Power Supply: Robust marine grade MOSFET Pulse Width Modulation power supply. Allows amplifier to product efficient power without taxing the boats electrical system.
• Output Connections: Connection from amplifier are sealed and grommeted.
• LED System Protection Circuitry Diagnostics: Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel.
• Auto Turn-On: 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.

SMT Inside

The typical "through-hole" placement and the larger tolerances from human placement are dramatically improved with Surface Mount Technology. Circuit engineers can also design better circuits for power and sound quality because SMT components have tighter tolerances than larger "through-hole" components. SMT components are ideal for audio designed for all vehicles because of their lower mass and ability to withstand shock and vibration.
