About Aphex Systems
Aphex Systems was founded in 1975 in Massachusetts by Marvin Caesar and Curt Knoppel, the inventor of the Aural Exciter™.

The first Aural Exciter™ units were available exclusively on the rental basis of $30 per minute of finished recorded time.

The unit became so popular, especially with the Los Angeles music/recording studio crowd, that Aphex had to move to Hollywood.

Recognizing that there was a much bigger market than just the rental business, Aphex started selling the professional units, and introduced two low-cost models: Type B and Type C. The Aural Exciter circuit is now licensed by a growing list of manufacturers, including Yamaha, MacKenzie, Gentner, Emu and Bogen.

Aphex is dedicated to the development of high-quality products for the professional audio, broadcast, fixed installation, touring-sound and home-recording markets. Through that dedication, Aphex has developed a number of industry-standard devices, such as the Compellor®, Dominator®, Expander/Gate™ and Expressor,™ plus the Model 1100 Two-Channel and Model 1788 Eight-Channel Ultra-Precision Remotely Controllable Microphone Pre-Amplifiers, and the Model 2020 Mk III Broadcast Audio Processor.

Each product contains one or more of the over 30 proprietary inventions (patented or patents pending). A key element of all the dynamics processing products is the firm's state-of-the-art Voltage Controlled Attenuator, the Aphex VCA 1001.

Another key element is Aphex' unique input and output circuitry. Using electronic servo-balancing techniques, the company's I/O stages offer all of the safety of audio transformers, but with pure sonic quality. Such circuits have made Aphex distribution amplifiers and level interfaces the "asked-for" products amongst engineers, producers and system designers that demand quality. Aphex offices, engineering laboratories, production and warehousing are located in a 16,000 square foot facility in Sun Valley, CA. All products are designed and manufactured in this facility.
