LOW NOISE PRE-AMPLIFIER CIRCUITRY 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 audio connection and resist corrosion
OPERATION MODE Mono only
CROSSOVER TYPE Internal crossovers networks allow for audiophile control of equalization circuits
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 Super D-Classâ„¢ 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 TECHNOLOGY The Ultra-Fiâ„¢ 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-Fiâ„¢ 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 Molded and Angled
Secure connection for all Power, Ground and Speaker connections. Angled for ease of access while creating a clean wire mangement profile
FULL-RANGE RCA OUTPUTS FOR SIGNAL PASS THROUGH Preamp RCA outputs to daisy chain multiple amps eliminate additional signal cables from the source unit
LED SYSTEM PROTECTION CIRCUITRY DIAGNOSTICS Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel
BASS REMOTE INCLUDED Wired Bass Remote allows adjustments to bass frequencies from the control which can be mounted anywhere in the vehicle.
PHASE ADJUSTMENT Phase 0-180°.
