Input Assignment

NOTE: Some older laser discs do not contain digital audio tracks. You will not hear audio when playing these discs if you have selected a digital input as the V-DISC source.

The four DC-1 digital audio inputs include two coaxial (RCA) and two optical connectors (TOSLINK™). For maximum configuration flexibility, each of the four digital inputs can be assigned to any (or all) of the source selections.

Video Input Assignment

NOTE: S-Video input signals will be output on both the composite and S-Video jacks. However, if you are only connecting to the monitor via the S-Video output, composite video input sources will not be dis- played.

Record/Zone2 Output

Blocking

Remote Trigger Assignment

The inputs labeled VCR1, VCR2, V-DISC, TV, and AUX normally have corresponding video inputs. The inputs labeled CD, TUNER, and TAPE do not have associated video inputs, and default to the video input VCR1. For maximum configuration flexibility, each of the five video inputs can be assigned to a different source selector. If the assigned video input has both S-Video and composite jacks, the S-video signal takes priority whenever a cable is plugged into the appropriate S-video connector.

This feature provides feedback protection when selecting a record source. BLOCKED input sources cannot be selected for the record outputs, thus disabling the record function. Normally, the record outputs are disabled for only the TAPE and VCR1 inputs. This sub-menu allows you to alter these defaults for other configurations.

ANALOG allows maximum flexibility by utilizing both the digital and analog connections of a digital source component (provided both are attached). The DC-1 processes the digital input signal for the main zone, and simultaneously routes the analog input signal to the Record and Zone 2 outputs. Since no D/A converters are necessary for the analog input signal, the functionality in the Main zone is not compromised.

DIGITAL routes the digital signal, assigned to the input, to the DC-1’s 20- bit Digital to Analog (D/A) converters. After conversion, the signal is sent to the Record and Zone 2 outputs. As this setup bypasses the D/A convert- ers in the source component, and utilizes the 20-bit D/A converters in the DC-1, sound quality can be dramatically improved when recording or listening in Zone 2. This setup automatically engages Effect Bypass.

BLOCKED simply blocks the input from being sent to the Record and Zone 2 outputs. This prevents feedback from occurring with devices that have both an input and output attached to the DC-1 (Tape, VCR, etc.).

This menu item assigns the status for the remote trigger that appears on pin 5 of the Power Control DIN jack on the DC-1 rear panel. +12VDC is provided for controlling ancillary equipment or functions. This signal can be ENABLED or DISABLED for the selected input. The factory default is ENABLED (high) for A/V inputs and DISABLED (low) for audio only inputs. (+5VDC is available via internal jumper. Contact your dealer or Lexicon Customer Service to perform this change.)
