DC-1 Digital Controller

When using a 48kHz digital connection from a source (DSS, DAT), the following effects are available:

THX Cinema

Two Channel

Logic 7

Music Logic

Pro Logic

TV Matrix

Music Surround

 

Note that current "AC-3 ready" laser disc and LD/DVD players do not

"AC-3 Ready" Laser Disc and

output a single digital audio bitstream that incorporates the Dolby Digital

(AC-3) data. Instead, the AC-3 data from laser discs is output on a separate

 

RCA jack in Radio Frequency (RF) form. To maintain the exceptional

 

performance of the DC-1, an outboard demodulator is required to turn this

 

RF signal back into a digital bitstream. By performing the necessary de-

 

modulation outside the DC-1, the potential for RF interference is elimi-

 

nated. The Lexicon LDD-1 is an excellent example of one such device. An

 

outboard demodulator is not required for DVD players.

 

For recording purposes, it is advisable to connect both the analog and digital outputs of your digital sources, as the record outputs do not have dedicated D/A converters. It is possible, however, to use the internal D/A converters in the DC-1 for recording. Select the input you want to record, then press the REC/ZONE 2 button until red LEDs above the REC/ZONE 2 and the corresponding input button light.

If a digital audio input is selected without a valid signal, or if a digital error which affects audio performance is detected, all audio outputs are muted and an error message is displayed. The associated input on the front panel will display a blinking red LED while the error condition persists. When valid data is restored, the error message is cleared and the unit returns to normal operation. The display indicates the sample rate and AC-3 (if appropriate) when a valid digital signal is being received. Whenever Emphasis is detected within the incoming digital audio channel status bits, de-emphasis is automatically applied.
