What's in the Box? Amplifier Bass Remote Owner's Manual Description:Hifonics 35th Anniversary 1700 watt Super D-Class™ Brutus Elite mono subwoofer amplifier with electronic crossovers, bass equalization and bass remote included.Hifonics offers Super A/B Class™ full range and Super D-Class™ mono subwoofer amplifiers to continue the 35th Anniversary celebration of Hifonics. The Brutus ELITE or “BE35” offers several 2 and 4 channel full range with several mono amps along with a killer 5 channel that utilizes both Super A/B Class™ and Super D-Class™ in the same amplifier – the best part is the 5th channel is 1 ohm stable, which is unheard of in five channel high performance amplifiers. The big bruiser in the line is the Brutus BE35 4000.1D delivering 4000 watts at 1ohm.Features: Hifonics Elite products are not available for Internet sales Accu-Cross crossovers allow complete control of the signal direction to all speakers Ultra-Fi™ MOSFETs product high power with high efficiency for coolig and minimal distortion Tiffany style RCA connectors for audiophile signal quality with minimum distortion Illuminated molded ad angled output connectors Super D-Class mono blocks include bass remote Low Noise Preamplifier CircuitryLow voltage signal from the source unit comes into the amplifier Preamplifier circuit with minimal distortion RCA InputsTiffany style RCA connectors for audiophile signal quality and maximum signal throughput with minimum distortion and maximum external noise rejection Operation ModeMono mode is intended for subwoofers only Crossover TypeAccu-Cross crossovers allow for complete control of the signal directing to all speakers. See specifications section for specific frequencies Electronic EqualizerControl 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 / TopologySuper D-Class™ designs which employ high-speed microprocessors with proprietary D/A conversion algorithms to efficiently control the current consumption. At very high listening levels, Hifonics amplifiers with Super D-Class circuitry result in lower distortion, higher current efficiencies and less heat than conventional D-Class amplifier designs Output Device TechnologyThe 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 SinkHeavy duty aluminum alloy heat-sink efficiently moves heat from the MOSFET where it can be cooled Power SupplyThe Twin Turbo Coil PS is a Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices Output ConnectionsNickel-plated, high temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant Connection TypeSecure connection for all power, ground and speaker connections. Angled for ease of access during installation. Full-Range RCA Outputs for Signal Pass ThroughOne pair of Tiffany style connectors for a full range, L & R output allow distortion free signal to be passed through this amplifier to feed that signal to other components without the need for noise generating Y cables LED System Protection Circuitry DiagnosticsMonitor overload and speaker short protection with illuminated indicators on the amplifier end panel Bass Remote IncludedWired Bass Remote allows adjustments to bass frequencies from the control which can be mounted anywhere in the vehicle. Smooth potentiometer and ringed illumination in a satin black mount create a custom look Specifications: Class: Super D Class™ Variable Voltage: 0.2V - 6V Signal to Noise: >90dB Frequency Response: 100Hz - 300Hz Crossover: Electronic Variable Low Pass Crossover 12dB per Octave: 40Hz - 300Hz Tone Control/Parametric EQ: Bass EQ Bass Boost: 0~9dB@45Hz Subsonic Filter: 10Hz - 40Hz Power @ 1 Ohm: 1 x 1700 Watts Power @ 2 Ohms: 1 x 1200 Watts Power @ 4 Ohms: 1 x 600 Watts Total Channels: Mono Audio Inputs: Yes Power Terminal 12v/GND: 4 AWG Speaker Terminal Wire Gauge: 12 AWG Total Harmonic Distortion (THD):
