Dolby LP8D84X12 Lake LP8D8 4X12 Processor

Dolby LP8D84X12 Lake LP8D8 4X12 Processor

The Dolby® Lake® 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 4‐in, 12‐out loudspeaker applications and 8 in, 8‐out EQ applications. The signal processing can also be changed to provide an EQ 4×4 configuration together with a loudspeaker 2×6 configuration. The Processor includes several advanced technologies for improving sound quality. These include Raised Cosine Equalization™ (the foundation underlying the Ideal Graphic EQ™ and Lake Mesa EQ™ interfaces), plus linear phase crossovers, LimiterMax™ loudspeaker protection, and Iso‐Float™ ground isolation.
