Aphex - Aural Exciter Type B Audio component

Aural Exciter Type B is an audio processor that enhances recording quality without saturating the signal.

This processor allows adjustments in Tune, Harmonics, and Drive, and has a frequency response of 10 Hz to 38 kHz, with a dynamic range of 120 dB. The Aural Exciter has been used in recording studios and is known for its ability to improve presence and the acoustic feel in recordings and to make voices sound more "airy".

Improve muted recordings, especially analog magnetic tape recordings that have lost their "shine" due to repeated overdubs.

Restore old recordings by simulating the spectral content that has been lost.

As an audio enhancement for hardware and software media players..

Since its introduction the Aphex Aural Exciter Type B has been used on numerous successful albums, films, and radio stations around the world, contributing to its reputation as a significant audio enhancement device. Users appreciate its ability to provide a dramatic improvement in audio quality at a relatively low cost, making it a valuable addition to any audio setup. It is a very well-built, easy-to-use device with many interesting applications and areas to explore in the studio, the tape duplication room, and in sound reinforcement operations. It was gratifying to see that the manufacturers had made the device easily compatible with operation at -10 dBV, which is the operating level most people in home recording will use. At the same time, it is easily switchable for professional +4 dBV operation.

Aphex operates on the principle of generating, within its circuits, fourth- and fifth-order harmonics of the input signal that are mixed back into the input signal at the output. The harmonic structure of each sound or instrument, therefore, is reinforced, allowing it to stand out from others. This manifests as a perceived increase in clarity or an increase in treble without a measurable increase in level.

Manufactured in the United States in the early to mid-1980s

Works perfectly, although it shows external signs of use.
