compressor module, feedback eliminator and the 120A Subharmonic Synthesizer on the input, with a
six channel output system that includes parametric EQs, and Peak Plus
limiters (which are used to
provide protection against speaker blowouts) and alignment delay. These features combined with the
Wizard setup system, represent a methodical design that is guaranteed to deliver optimal, all-inclusive
processing in a completely scalable system. For more information, please visit: www.dbxpro.com.
