High-quality Aftermarket Speakers

MB Quart’s Reference Series RA1-280.4 four-channel amplifier provides 50 watts of power to two pairs of speakers, so you can hear and feel your music clearly over road and engine noise. Designed to power high-quality aftermarket speakers, like their Reference Series speakers and components, this Class D amplifier utilizes MB Quart’s unique Q-Stasis (Class SQ) circuitry to improve the accuracy and clarity of your music.

High-pass Filter Shapes

The amplifier’s features include speaker-level inputs with signal-sensing amp turn-on, so it’s ready to work in almost any system. A high-pass filter shapes the signal to fit your full-range speakers for their best-sounding output. You can also configure this amp for two-channel operation to power a pair of subwoofers with up to 140 watts each or for three-channel operation to power a pair of speakers with 50 watts each while powering a sub with 140 watts. A low-pass filter and a bass boost EQ help dial in just the right kind of bass bump you like.

Innovative Sound Quality and Power Technology

MB Quart Reference series four channel car audio amplifier featuring innovative sound quality and power technology. The RA1-280.4 is a 280 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.Q-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion.

High Temperature Impact Resistant

Nickel-Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant. Variable electronic crossovers allow for complete control of the sound.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.

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 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.
