  • 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.
