Current Feedback Amplification Circuit

By employing a current feedback amplification circuit, Clarion’s APA4300HX paves the way to high-definition audio formats such as DVD-Audio. This unique design maximizes the potential of an amplifier, allowing it to realize even ultra-high frequency levels of 100kHz. This wideband, high-speed amplification circuit also ensures stable phase characteristics and response.

Melding Rich Sound With Crystal Clear Harmonics

Fielding ultra-high frequency sound in the range of 100kHz, this amplification circuit provides your music with additional harmonic elements while maintaining the main frequency element. The result is added dimension to your sound.

Ultra High-Range Reproduction Cancels Phase Shift

Unlike conventional amps, which allow phase shifts of high-range frequencies to become audible, Clarion’s APA4300HX — equipped with a current feedback amplification circuit — cancels these sound-hindering interruptions. The result is crystal clear sound.

Aluminum Heat Sinks and Forced Cooling Fan

For superior heat dissipation, Clarion’s APA4300HX employs a large, tunnelshaped sub heat sink, as well as an internal, heat-sensitive fan. Located to the center of the chassis, the fan adds additional heat protection to internal parts. This means the amplifier will maintain peak performance even when operating under extreme conditions.

Direct Input Terminal

The longer an audio signal travels the more chance there is for sound quality degradation. By employing a direct input terminal, the audio signal travels a shorter distance from input to output during amplification, allowing the signal to maintain its original form. The straight and non-contact circuit also eliminates any contact points that can potentially harm your system’s sound quality. This results in a smooth signal transfer and superior performance.

Power Guard Circuit

The APA4300HX’s input stage prevents the generation of clipping distortion by holding down the gain when overdrive distortion is detected at the output stage. By removing only distortion elements, the amplifier protects your speakers from potential damage while also maintaining its superior sound qualities.

4-Part Digital Meter

Stay in tune with your amplifier with the APA4300HX’s 4-Part digital meter. Monitor your amp’s real-time power output level and consumption, voltage level and internal temperature.

Low-Pass and High-Pass Filters

Outfitted with built-in low-pass and high-pass filters (-24 dB/oct.), the APA4300HX allows for adjustment in the 50Hz to 200Hz frequency range over all channels. This setup is ideal when operating a system that touts multiple amplifiers and subwoofers.

Input Mixing

Clarion equips its APA4300HX with an input mixing function, a key feature when bridging the left and right signals. Combined with the unit’s built-in low-pass and high-pass filters, users get an amplifier that harmoniously compliments a lowfrequency- fielding subwoofer.

Low-Loss High-Output Power Supply

The APA4300HX’s input stage prevents the generation of clipping distortion by holding down the gain when overdrive distortion is detected at the output stage. By removing only distortion elements, the amplifier protects your speakers from potential damage while also maintaining its superior sound qualities.
