Maximize your audio with the Compellor!

The 320D Compellor audio level controller from Aphex fits into any broadcast, studio, or live sound rig and serves as a great way to compress and limit program material. This 1U rackmountable unit delivers intelligent compressor action, leveling, and peak limiting simultaneously to solve audio level problems and improve audio signals. The 320D Compellor converts between acting as two independent mono processors and one linked stereo processor by front panel selection. This is true with both analog and digital I/O. Get the most out of your audio with the 320D Compellor!

Aphex 320D Compellor at a Glance:

• A/D or D/A
  
• Proprietary Aphex Technology
  
• Legacy

A/D or D/A
The 320D serves as a fine A to D converter with processing. When you use the analog input, the digital output contains the Compellor's processing and is ready for use in almost any application. Conversely, the 320D serves as a fine D to A converter. When you use the digital input, the analog output contains the Compellor's processing and is properly leveled and packaged. The professional analog audio inputs and outputs are fully balanced and adapt to consumer or professional operating levels at the touch of a button. Analog or digital source selection is made at the rear panel.

Proprietary Aphex Technology
The Compellor circuits are totally unique. By throwing away all conventional design ideas, we created audio processing with unprecedented sound transparency yet is exceedingly effective at controlling levels. Because our designs are patented, no other company has been able to match the performance. Algorithms such as our DVG, DRC, and FDL have yet to find any rivals. Aphex engineering and manufacturing produce products that last and last without needing repairs or calibration. Some Compellors have literally been in 24-hour use in the same rack for a decade, or longer! When you specify a Compellor, you know it will do its job flawlessly and give you peace of mind.

Legacy
The first Compellor was introduced in 1983 as an analog product. Because of their advanced technology, most of those older units are still in regular use. Since that time, newer models have been produced, still in analog form. Digital technology of today promises many improvements in user interfaces, and sometimes in sound quality, but not in audio processing algorithms. No digital processor can match an analog Compellor for sound quality and effectiveness. Nevertheless, many of today's systems need a Compellor that can interface to digital audio. With the Model 320D, Aphex brings you just that. You get all the advantages of the analog processor with AES3 connectivity.
