• High Level Inputs: See Auto-Sense Feature.
• Operation Mode: 2 / 4 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 D 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: Aluminum: Quickly dissipates heat to allow the amplifier to run lower impedance for longer duration.
• Power Supply; Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to produce 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: –
• Bass Remote Included: –
• 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.
