MB Quart RA1-1100.4 1100 Watt 4-Channel Amplifier Class D Car Stereo Amp

Description:

MB Quart Reference series 4-channel car audio amplifier featuring innovative sound quality and power technology. The RA1-1100.4 is a 1100 watt car audio amplifier. Reference amplifiers feature DC Sensing to allow any amplifier to be easy integrated into an OEM system by simply adapting a RCA cable from the source unit.

Features & Benefits:

• 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
  
  • Nickel-Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.
• 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.
• 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.
