Description of FA1-900.5:

MB Quart Formula series five channel car audio amplifier featuring innovative sound quality and power technolgy to run four full range channel and a subwoofer channel. The FA1-900.5 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 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:
  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:
  Innovative use of Class SQ (Class A/B) for full range and a Class Q1 (Class-D) amplifier to drive the subwoofer frequencies
• 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 respond of the audio system from the seated listening position.
