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. No all-digital products have been able to approach
it. In this digital age, that builds a strong argument to add digital I/O capability to Compellors.
This has been accomplished with the Model 320D which contains both analog and digital
audio I/O capabilities.
