MB Quart Formula Series 900 Watt 5 Channel Stereo Amplifier FA2-900.5

MB Quart Formula series compact five channel car audio amplifier featuring innovative sound quality and power technology to run four full range channel and a subwoofer channel. The FA2-900.5 is a 900 watt 1 ohm stable (channel 5 only) car audio amplifier. Formula 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. Bass remote is included.

Features:

• 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 nickel-plated RCA inputs that allow for secure connections and is erosion resistant.
• High 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
  • 5 Channel 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 Q1 (Class D): MB Quart’s Class Q1 offers the efficiency of today’s D-Class with increased engineering to focus on sound quality from the power supply through the output devices, the FLUID-FETS.
• 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.
• Bass Remote Included
  • Included on mono and 5 channel amplifiers. This allows the driver to make subtle changes to the bass response of the audio system from the seated listening position.
• 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.
