CARVER DPL-33 SURROUND SOUND PROCESSOR DOLBY PROLOGIC RACK MOUNT W/ SUBWOOFER CONTROL *NEW* - Serviced and Tested at NORTHWEST AUDIO ** CASH ONLY - Make an Offer At the heart of the DPL-33 is Dolby's most advanced surround sound technology, circuitry that closely approximates the Dolby Stereo effects found in many state-of-the-art theaters. Instead of just front and rear channels, Pro Logic uses three different outputs (rear left and right channels are monophonic, ie, the same) and five amplifier channels, three of which are built into the DPL-33. The key to the system is center channel active logic steering that provides a natural sound stage and a realistic simulation of the environment seen on the video screen, independent of viewer position. The DPL-33 also features Dolby's latest auto-balance circuits that continuously monitor and adjust the relative levels of the source material input for proper decoding. For conventional stereo sources, we have provided a hall ambience generator that convincingly simulates the sound of a live concert hall. For monophonic inputs, such as most TV programs and older movies, the DPL-33 has a matrix stereo synthesizer that adds a worthwhile spacial dimension. We've also included a subwoofer output fed by its own built-in electronic crossover, giving you the option of further increasing the impact of modern VHS Hi-Fi and laser disc movie soundtracks.
