General and Features This multi-purpose studio digital video cassette recorder uses 1/4-inch compact video cassette tapes, and it is designed to record, playback and edit both interlace signals (525i/ 625i, 50 Mbps recording rate) and progressive signals (525p)* as well as record and play back existing DVCPRO signals (25 Mbps). Its 525/625 switching function makes this a studio video cassette recorder which can be used anywhere in the world.
Features (continued) Multifunctional interface • Serial digital input/output The component serial interface, a standard feature, allows for interfacing with progressive signals* and component signals in serial digital (SMPTE259M-C, 272M, 294M*). • Analog video input/output Analog component input/output signals (Y, PB , PR) as well as composite input/output signals are standard feature. • AES/EBU audio input/output Digital audio input/output connectors are featured.

Change the digit now flashing on the display. Each time the button is pressed, the flashing moves to the right by one digit, and when it reaches the right-most digit, it returns to the left-most digit. When it is kept depressed, the flashing moves consecutively.
$7 Volume control This is used to adjust the headphones volume and the monitor output volume. Whether the headphones output and monitor output volumes are to be linked or kept separate can be set on the setup menu No. 713 (MONI OUT). (Note that the headphones output volume is normally linked.) When the volumes are kept separate, the monitor output is set to the unity value (preset value).
Controls and their functions (continued) %0 VIDEO IN LEVEL control and switch These are used to adjust the video input level. PRESET: When the switch is set to “PRESET”, the video input level is set to the unity value (0 dB). MANUAL: When the switch is set to “MANUAL”, the video input level can be adjusted using this control. %1 VIDEO OUT LEVEL control and switch When setup menu No. 00 (ENCODER SEL) is set to “LOCAL”, the video output level can be adjusted.
%7 REC INHIBIT switch This is used to inhibit or allow recordings on the video cassette tape. ON: Recording on the tape is inhibited. At this setting, the REC INHIBIT lamp in the front panel lights. OFF: Recording on the tape is allowed provided that the accidental erasure prevention tab on the video cassette tape enables recording to be conducted. %8 TV SYSTEM selector switch This selects the type of television system.

Servo reference This unit automatically selects the input video signal selected by the INPUT switch, the reference video signal supplied from the REF VIDEO input connector or the internal sync signal as the servo reference signal. When the signal is selected, the unit's mode and servo reference stand in the relationship shown in the flowchart presented below. EXT 1 What is the SERVO REF on the setup menu No.
Servo reference setting tables The servo reference signal is switched as shown in the tables below depending on the servo reference setting, deck mode and what input signal is available. When the mode is transferred to editing or recording/playback, the image may be disturbed and the transfer may be delayed if the references during playback and recording do not match. ■ During playback or special playback SERVO REF on the setup menu No.
Audio V Fade Function When editing tapes, the edit point splicing selection (setup menu No. 311 and 312) information is recorded on the tape. This information is then sensed during playback, and V fade or cut processing is automatically performed for these sections.
