Processor marks the next generation in digital loudspeaker and
equalization technology. With unsurpassed audio quality and the most advanced
loudspeaker processing available, it will improve the sound of any system. Effortless
control is provided through the Dolby Lake Controller software, or the exclusive
front-panel Portal metering and control interface.
The Processor platform offers complete, native-digital signal processing functionality,
with support for up to four-in by twelve-out for loudspeaker applications and eight-in
by eight-out for EQ applications. The signal processing can also be changed to
provide an EQ 4

4 together with a loudspeaker 2

The Processor includes several advanced technologies for improving sound quality.
These include Raised Cosine Equalization
TM
(the foundation underlying the
revolutionary Ideal Graphic EQ
TM
and Lake Mesa EQ

interfaces), plus linear phase
crossovers, LimiterMax

loudspeaker protection, and Iso-Float

ground isolation.
Four slots provide additional configurability, for adding analog I/O and other
capabilities via expansion cards. The Processor comes in five preconfigured versions.
Converter cards can be easily added at any time, in the shop or in the field, to meet
changing needs.
