• LOW NOISE PREAMPLIFIER CIRCUITRY
• Q-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion
• RCA INPUTS
• Nickel Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant
• HI LEVEL INPUTS
• 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.
• OPERATION MODE
• 4 channel operation mode allows either stereo or mono bridged operation
• 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
• Heavy duty heat-sink efficiently moves heat from the MOSFET where it can be cooled
• POWER SUPPLY
• Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to product efficient power without taxing the vehicle electrical system
• OUTPUT CONNECTIONS
• Heavy duty connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier
• CONNECTION TYPE
• Secure connection for all power, ground and speaker connections.
• LED SYSTEM PROTECTION CIRCUITRY DIAGNOSTICS
• Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel
