High-end 4-channel amplifier

Brax amplifiers represent German reference-grade engineering with no cost constraints.

Designed by the team behind Helix, these are built for installations where technical excellence matters more than price.

Brax exists for serious installations where proper system design, professional integration, and uncompromising performance justify the investment.

4 channel high-end car amplifier

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
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
