The Brax MX4 PRO 4 Channel Amplifier with its mere 4 x 300 RMS into 4/2/1 Ohms delivers more power to the speaker terminals.

This is the perfect symbiosis of state-of-the-art components and ingenious technological improvements without neglecting the heritage and the tradition of the brand that BRAX is famous for. The MX4 PRO is as well a paradigm for bridging the gap between traditional amplifier technology and the digital era.  We have made an unparalleled effort just for the volume control of the digital inputs.

Main Features:

 

  • Two digital stereo digital inputs in SPDIF format (optical and electrical) with a sampling rate up to 192 kHz
  • DiSAC (Digital Signal Analog Controlled) volume control for the digital signal inputs, controllable via BRAX DSP
  • Optimized quad-layer PCB design for maximized power and signal flow and increased output power
  • Lossless switching of the input signals via relays with gold-plated contacts
  • Best possible impulse response due to abstinence of coupling capacitors in the signal path
  • Incredible damping factor of more than 1,400 @ 4 Ohms for perfect speaker control
  • Maximized signal-to-noise ratio due to power supply synchronization
  • Extremely complex and regulated switch-mode power supply
  • Eightfold-contacted capacitors with a total capacitance of 40,000 μF and lowest possible ESR as well as a 300 A suppressor choke coil to smooth power supply peak currents
  • Separate connector for BRAX power stabilizer
  • The switched power supply of the BRAX MX4 PRO assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.
  • Loudspeaker protection circuit via sophisticated high current power relays
  • Specially designed toroidal transformers made of high permeability core materials for highest possible saturation currents
  • 32 hand-selected high-end MOSFET transistors for lowest tolerances and outstanding measurement data
  • Engraved serial number on a stainless steel plate
  • Impedance independent output power of  300 Watts RMS per channel
  • 4, 2 and 1 Ohms stable
  • Processor and temperature controlled fan in bottom plate
  • Massive heat sink made of a special aluminum alloy for optimum cooling of all power transistors

Special Features:

 

  • DiSAC (Digital Signal Analog Controlled) volume control in combination with the BRAX DSP – In a car audio system, there are typically two possibilities to control the playback volume:  a) The volume will be adjusted in the signal source (e.g. the car radio / head unit). b) The volume will be adjusted in the digital signal processor (DSP)
  • The perfect solution – The MX4 PRO in combination with the BRAX DSP follows a different, yet the most consequent and extensive approach in order to avoid any degradation of sound quality. Audiotec Fischers exclusive and proprietary “DiSAC” technology operates perfectly if either the audio source does not incorporate any volume adjustment or the source always delivers a high signal level. The speciality lies in the fact that the volume information from the remote will be encoded inside the BRAX DSP and embedded into the digital audio data stream of the SPDIF outputs and thus transferred to the MX4 PRO. The MX4 PRO itself is able to extract and decode the volume information from the digital data stream, using this to adjust the lossless analog volume controllers (PGA’s) after the DA converters.
  • Start-Stop capability – The switched power supply of the BRAX MX4 PRO assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.
