Aphex Systems 320A owner manual

Page 9

In 1994, Aphex introduced the current Compellor Models 320A and 323A. The model “A” revision signifies the inclusion of an improved patented Leveler circuit called the “Frequency Discriminate Leveler” (FDL) while all other aspects of the Model 320 remain the same. With the FDL, Compellors became even more transparent and useful than ever before.

Now, in 2003 (as this manual is being written), the Compellor is still the most advanced and effective audio level controller available.
