Hifonics BRUTUS GAMMA Four Channel audio amplifier delivers 1600 watts with Super A/B Class™ technology that features Ultra-Fi™ MOSFET outputs that are selected for both balance and output power.


  • Low Noise Preamplifier Circuit: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion.
  • RCA Inputs: Nickel-plated RCA jacks create the most effiecient High/Low Level audio connection and resist corrosion.
  • Operation Mode: 4 channel operation mode allows either stereo or mono bridged 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.
  • Class/Topology: Super A/B Class proprietary designs use high-speed microprocessors with proprietary D/A conversion algorithms to efficiently control the current consumption. At very high listening levels, this unique hybrid of Super A/B Technology results in lower distortion, higher current efficiencies and less heat than conventional amplifier designs.
  • Output Device Technology: Pro-Fi? Output Device Technology
    The Ultra-Fi? MOSFET is designed for music production vs just electronics output power. It produces very musical high power with high efficiency for cooling and minimal distortion.
  • Heat Sink: Classic aluminum Hifonics design to minimize heat build up on the Ultra-Fi? output devices.
  • Power Supply: Simpatico Coil Design
    The dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices.
  • Output Connections: High temperature impact resistant nickel plated connectors with allen head set screws which allow for secure termination of wire and creates an erosion resistant seal.
  • Connection Type: Secure molded connection terminal for all Power, Ground and Speaker connections. Angled for ease of access while creating a clean wire mangement profile.
  • LED System Protection Circuitry Diagnostics: Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel.
