Hifonics A2500.5D ALPHA Super D-Class 5 Channel Amplifier

The Hifonics ALPHA A-2500.5D amplifier is a 5 channel amplifier with a hybrid of Full Range Super D-Class® and Super D-Class® Technologies with electronic crossovers. Bass remote included.

The Hifonics ALPHA A-2500.5D amplifier is a 5 channel amplifier with a hybrid of Full Range Super D-Class® and Super D-Class® Technologies. Engineered and manufactured with voltage matched, tight tolerance and hand selected proprietary components on the double sided glass epoxy PC board, ALPHA delivers Hifonics best ever sound quality and power output. The innovative use of SMT (Surface Mount) and through-hole components are designed to fit into a much smaller package than other amplifiers available from Hifonics.

LOW NOISE PREAMPLIFIER CIRCUITRY
Maximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process
RCA INPUTS
Nickel plated RCA connectors for audiophile signal quality and maximum signal throughput with minimum distortion and maximum external noise rejection
OPERATION MODE
Flexible installation allows this amplifier to run in four channel or mono mode simultaneously
CROSSOVER TYPE
Accu-Cross crossovers allow for complete control of the signal directing to all speakers. See specifications section for specific frequencies
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
Developed over 4 decades of engineering to deliver the highest level of sound quality and power efficiency. Hifonics ALPHA Super D-Class® and Full Ranger Super D-Class hybrid Five Channel topology results in lower distortion, higher current efficiencies and less heat than conventional amplifier designs
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
Heavy duty aluminum alloy heat-sink efficiently moves heat from the MOSFET where it can be cooled
POWER SUPPLY
The Twin Turbo Coil PS is a Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices
OUTPUT CONNECTIONS
Nickel plated, high temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant
CONNECTION TYPE
Secure connection for all power, ground and speaker connections. Angled for ease of access during installation.
LED SYSTEM PROTECTION CIRCUITRY DIAGNOSTICS
Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel
BASS REMOTE INCLUDED
HFR-31
Wired 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
Channel 5 Only
FULL RANGE DIGITAL
Full Range Super D Class, high efficiency/high power technology to deliver maximum wattage. With this focus on engineering, big sound while remaining very musical in a compact chassis is the result.
SMT INSIDE
With Surface Mount Technology the typical "through-hole" placement and the larger tolerances from human placement is dramatically improved. In addition, circuit engineers can design better circuits for power and sound quality as the tolerances of SMT components are superior to larger "through-hole" components.
Because of their lower mass SMT components withstand shock and vibration making them perfect for audio designed for all vehicles.
300KHZ HIGH SPEED PULSING
The switching speed of the Class D chip puts the amplifier sampling frequencies at over 100 times higher than human ears can hear. This means that the amplifier and the very fast digital switching remains unhearable in the audio bandwidth for music.
