Introduction Introduction to the DC-1 to the1 DC-1 DC-1 Digital Controller Introduction More than just a surround processor, the DC-1 is a digital control center with state-of-the-art performance and flexibility. A superb line level preamp, the DC-1 provides 8 audio, 5 video (3 S-VHS), and 4 digital (2 coaxial, 2 optical) inputs. The video and digital inputs can be assigned to any of the audio inputs for custom configuration. The digital inputs are processed through true 20-bit D/A converters, p

Introduction to the DC-1 Lexicon The key to our perception of the acoustic space we inhabit lies in the lateral sound field – the sound which moves from side to side in the room. The two front speakers used in conventional two channel stereo do not adequately excite these lateral fields in a playback room. The speakers are too far forward, and the ambient information in the recording is often masked by the music itself. The DC-1 extracts or synthesizes the ambient information, and uses additiona

Introduction to the DC-1 DC-1 Digital Controller The DC-1 also has the ability to create an acoustic environment which is not present on the original recording. Using the Nightclub, Concert Hall, Church and Cathedral effects, you can select the acoustics the digital processor will simulate. Each of these effects has many adjustments to allow you to generate just the right sound for a particular piece of music in your room. In addition, the DC-1 includes the Panorama effect, which cancels the cro

Introduction to the DC-1 Lexicon Designed specifically to handle multichannel audio, AC-3 takes advantage of a psychoacoustic phenomenon known as auditory masking. It divides the audio spectrum of each channel into narrow frequency bands of different sizes optimized with respect to the frequency selectivity of human hearing. This makes it possible to sharply filter coding noise so that it is forced to stay very close in frequency to the frequency components of the audio signal being coded. By re

Installation and Calibration Lexicon Wiring Considerations Audio/Video Cables There is controversy over the audible effects of different types of intercon- nects. Good engineering practices have minimized the effect that cables might have on the inputs and outputs of the DC-1 — but feel free to evaluate different interconnects in your system. If you want to do some tweaking, be conscious of the mechanical stress from repeated insertion and overly tight connectors, and the possibly corrosive na
