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 |
With Surface Mount Technology the typical "through-hole" placement and the larger tolerances from human placement is dramatically improved. In addition, circuit engineers can design better circuits for power and sound quality as the tolerances of SMT components are superior to larger "through-hole" components. Because of their lower mass SMT components withstand shock and vibration making them perfect for audio designed for all vehicles. |
