For over 40 years, Aphex has been designing and manufacturing unique analog audio equipment for the recording studio, broadcast, live and installation industries.

Aphex is known for its high-quality builds and patented analog circuits, most notably the Exciter circuit which has been audio engineer’s ‘secret weapon’ for over four decades, effortlessly transforming lifeless, dull audio into ear candy.

Aphex aims to create timeless analog solutions for pure sonic quality.


320D Compellor

The 320D Compellor is a 2-channel automatic analog level controller with analog and digital I/O. It contains Aphex’s patented compression technology using 3 discrete gain controllers in combination: a frequency-discriminate leveller, a compressor and a limiter, working simultaneously to invisibly control the dynamics of the audio stream delivering the perfect experience for your audience. A staple in broadcast studios for decades, the 320D provides audio level control with unprecedented sound transparency meaning there is never pumping or other audio artifacts, just natural sound that is evenly consistent in loudness. Some Compellors have been in 24-hour use in the same rack for a decade or longer so when you specify a Compellor, you know it will do its job flawlessly time and time again.

Since its introduction in 1975, close to a million Aphex Aural Exciters have found their way into recording studios, broadcast facilities, FOH and DJ rigs and installation setups. The latest iteration, the Aphex Exciter, is a 2-channel signal enhancement unit designed for extremely powerful broad stroke signal enhancement of the high and low end of your audio. The Big Bottom adds deep, powerful low-frequency punch without unwanted level boost that comes from traditional EQs and also includes a musical optical compressor for dynamics control. The Aural Exciter brings out detail, clarity and presence, dramatically increasing speech intelligibility.

The Aphex Model 120B is a high performance 4-channel audio distribution amplifier with a single XLR balanced input and 4 electronically servo-balanced outputs making it ideal for distributing audio in multi-zone installed applications. The transformer-less, servo-balanced design will output clean, undistorted audio with an extremely flat frequency response, free from ringing or overshoot with negligible noise and hum. If you need additional outputs several Model 120B units can be daisy chained together using the loop through output, perfect for multi-zone audio distribution. Not only can the Model 120B distribute audio but also SMPTE time code in audio production facility applications.

The 124B is an Audio Level Interface designed to allow use of -10dBV consumer hi-fi equipment with +4 line level pro-audio gear. It provides an extremely clean, reliable two-way buffer to connect the two levels so that both systems can operate at optimal performance, matching impedances and operating levels. The Aphex 124B solves connection problems through its simple, high-quality design removing distortion and instability that can result when gear is not correctly connected together. The Aphex Model 124B features stereo inputs and outputs for both the balanced and unbalanced connections.

The Aphex 141b is a workhorse digital to analog converter that allows you to easily expand the analog outputs of your setup, perfect for summing mixing. This small form factor ½ rack unit converts a digital signal on an ADAT input into 8 line level analog signals on a D-Sub connection. It features Aphex’s high-quality and transparent audio conversion with sample rates 44.1KHz and 48kHz available.
