Aphex Systems announces the release of their newest Aural Excitern++, the Aphex 204. Featuring the new Optical Big Bottomn++ for enhanced low-end response; two independent channels; internal power supply; XLR and 1/4-inch input and output connectors; and updated circuitry for improved overall sound quality and user flexibility, the 204 markedly increases presence and clarity of audio signals.
Extending the harmonics of the audio path, the 204 is able to restore the natural brightness, clarity, and presence that is often lost during analog/digital conversions, processing, or playback through 'less-than-perfect' audio equipment, bringing sound back to life. The Aural Exciter is ideal for a wide range of applications including sound recording and mixing, Radio and TV broadcast and production, streaming audio, live sound reinforcement, home theater, nightclubs, discos, theme parks and other fixed installations.

In addition to restoring natural brightness, the Aphex 204 provides greater perceived loudness, while improving sonic detail and intelligibility. The 204's tunable harmonics enhances the detail and presence of any instrument, voice or even an entire mix. The new Big Bottom with adjustable tune control provides deeper, more powerful bass performance without adding more power amplifiers or loudspeakers and with little or no increase in peak output.

The Model 204 features an elegant front-panel design and operator controls with a custom light-dependent resistor as the gain-control element.

Since its introduction over 25 years ago, the Aphex Aural Exciter technology has been used on thousands of hit albums and successful musical tours. The patented audio process recreates missing harmonics without generating significant changes in the actual signal level. Unlike equalizers and other brightness enhancers, which only boost the high frequencies, and often alter the overall tonal balance, the Aural Exciter actually extends the high frequencies. The stereo image is enhanced, resulting in a greater perceived loudness without an introduction of noise into the audio path due to increased gain.

The patented Big Bottom circuit dynamically shapes the bass response, increasing the perception of low frequencies without boosting the maximum peak output. The bass-frequency response is dynamically optimized to isolate and enhance the lowest bass frequencies and provides a deeper and more resonant bass without overloading the sound system.
