Introduction The AJ-D250 is a digital VTR which uses 1/4˝ wide tapes. The incorporation of digital compression technology ensures that the deterioration in picture and sound quality suffered during dubbing will be much less than with conventional analog systems. The model has a compact and lightweight design, enabling it to be readily carried about or easily installed in a rack.

Operation Setting the BEGIN and END points [Front panel] Set the unit to the local mode (by setting the LOCAL/MENU/REMOTE switch to the LOCAL position). When the BEGIN or END button on the front panel is pressed, the current position is set as the BEGIN or END point.
Time Codes and User’s Bit Time codes Time codes are used when recording time code signals generated by the time code generator on the tape, reading out their values with the time code reader, and displaying the absolute positions of the tape in increments of hours, minutes, seconds and frames. The time codes are written in the sub-code area (data area) of the helical track.
Time Codes and User’s Bit Setting the time code Set the unit to the menu mode (by setting the LOCAL/MENU/REMOTE switch to the MENU position). Select the “TC PRESET” setup menu item, and press the DATA+ button (PAUSE/STILL button) or DATA– button (PLAY button). (See page 32) Select the digit to be changed (blinking display) using the UP button (FF button) or DOWN button (STOP button).
Time Codes and User’s Bit Playing back the time code/user’s bit Set the unit to the STOP mode. Set to TC or UB using the COUNTER button. TC: The time code appears on the display. UB: The user’s bit appears on the display. O Interpolation is provided by the CTL signal if the time code cannot be read.
Superimposed Screens When the unit’s MONITOR OUT connector has been connected to a TV monitor, the control signals, time codes, etc. are displayed on the TV monitor screen as abbreviations. The display can be switched ON or OFF using the setup menu item No.

Editing Editing with the RS-232C remote control Using the RS-232C remote control (AJ-A250), which is available as an optional accessory, two units—a player VTR and a recorder VTR—can be controlled directly from the controller to enable speedier and more efficient assemble editing, insert editing and other editing jobs. Preparation: O As shown in the figure below, connect the player VTR and recorder VTR to the RS-232C remote control.
Audio editing functions The information (setup menu item No. 700, 701) concerning the selection of the joining method used at the edit points is recorded during digital audio editing, and this information is detected during playback so that the edit points can be processed automatically. This applies only when AUTO has been selected as the playback fade selection (setup menu item No.702) setting.
First Edit Function The CTL (control) signal must be recorded ahead of time onto the editing tape. The method used to record it differs depending on whether assemble editing or insert editing is to be performed. First edit for assemble editing In the case of a tape for assemble editing, the CTL signal is recorded at the beginning of where the recording is to be commenced.
RS-232C The following functions can be controlled using the RS-232C interface. $ Basic operations EJECT INSERT STOP SEARCH PAUSE PLAY SEARCH SPEED UP REC/PLAY SEARCH SPEED DOWN FORWARD/ADVANCE REVERSE/ADVANCE PAUSE REVERSE/PLAY COUNTER RESET DIRECT SEARCH $ Status checks The current VTR mode can be checked. $ Simple editing functions Video/audio, audio/video and various other insert editing operations can be performed.

If any command except a Q (query) command is sent while this switch is not at the REMOTE position, error code ER001 is returned.
Error Messages When a problem has occurred in the unit, one of the following error messages will appear on the tape counter. Error No. Description — d — Condensation (dew) has formed. Appears when the servo fails to lock for 3 or more seconds.
Emergency Eject Procedure for removing the tape manually in an emergency Use the procedure below to remove the cassette tape if it can not be removed even when the EJECT button is pressed. O Before proceeding to eject the tape manually, you must first turn off the power to the unit. 1 Remove the top panel.
Video Head Cleaning This unit is equipped with an auto head cleaning function which automatically reduces the amount of dirt on the video heads. However, in order to maximize the unit’s reliability, it is recommended that the video heads be cleaned as and when appropriate. For further details on how to actually clean the heads, consult with one of our service companies or with your dealer.
