• Operation Mode: Four Channel, Full Range, Bridgeable - Flexible installation allows this amplifier to run in four channel or bridged mono mode. Crossover / Signal Shaping: Accu-Cross and XCurve (X1/X10) - Accu-Cross crossovers allow for complete control of the signal directing to all speakers. XCurve allows for chosen frequencies to be as stated (X1) or multiplied by 10..
• Equalizer: ParaQ - Parametric Bass EQ with adjustments: Boost (0-10dB) ; Width (Narrow-Wide (On Center) ; Center Frequency (30Hz - 100Hz). Class / Topology: Super A/B Class - Developed over three decades of engineering to deliver the highest level of sound quality and power efficiency. At very high listening levels. Hifonics Super A/B Class results in lower distortion, higher current efficiencies and less heat than conventional amplifier designs..
• Output Devices Technology: Ultra-Fi MOSFET - 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: Aluminum - Heavy duty aluminum alloy heat-sink efficiently moves heat from the MOSFET where it can be cooled without the need for fans..
• Output Connections: Nickel-Plated - High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant. Connections Type: Molded and Angled - Hardened composite ing with secure connection for all Power, Ground and Speaker connections. Angled for ease of access during installation..
• Signal Pass Through: Yes - One pair of Tiffany style connectors for a full range, L and 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. Diagnostics: Three-stage protection circuits - Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel..

Hifonics 35th Anniversary SUPER AMPLIFIER. 4x150 Super A/B Class four channel car audio amplifier. Features on board ParaQ bass equalization and bass remote with diagnostic control. CONSUMER TECHNOLOGY ASSOCIATION. CTA stands for Consumer Technology Association and Hifonics has been a member for decades. In 2016 the program previously known as CEA Certification changed to CTA-2006B to reflect the changes to the organization and their initiatives. Specifically for the Hifonics Super Amps, the Primary Output Power should, according to CTA2006, be measured with 14.4V DC supply, a 4-ohm load and with 1% or less total harmonic distortion in the output.
