Introduction The AJ-D95DCP is a multi-purpose digital VTR which is capable not only of 525i/50 Mbps recording and playback using 1/4-inch wide compact cassette tapes but of recording and playback onto existing DVCPRO (25 Mbps) cassette tapes as well. This VTR with its high picture quality, which is due to the use of digital compression technology, significantly reduces the deterioration in the quality of both sound and picture accompanying dubbing operations.

Parts and Their Functions Front panel 1 POWER switch When this switch is pressed, the power is turned on and the counter display area lights; when it is pressed again, the power is turned off. : Level meter This displays the levels of the audio signals. The level of the input audio signals is displayed during recording and E-E selection; the level of the output audio signals is displayed during playback.
Parts and Their Functions > INPUT SELECT button and lamp This button is used to select the input signals. Each time it is pressed, ANALOG and SDI signals are selected alternately. It is not possible to select ANALOG for the video signals and SDI for the audio signals or vice versa: the same setting must be used for both sets of signals. ANALOG: This is selected when analog composite video signals and analog audio signals are input. When it is selected, the ANALOG lamp lights.
Parts and Their Functions H FF button This button is pressed to fast forward the tape. The playback pictures can be monitored when the TAPE/EE switch M is set to TAPE. Pressing the FF button while in the search mode (search still, reverse search, reverse search still, forward search still) causes operation to switch to forward search, and fast forward playback occurs at the speed selected using setting No. 100 on the setup menu. (See pages 15 and 30.

Tapes Types of tapes and their recording times DV tapes bearing either the “ ” or “ ” logo for regular consumer applications cannot be used. Do not insert them into the unit. M size cassettes O 50 Mbps mode Tapes with a recording/playback length of up to 33 minutes: O 25 Mbps mode Tapes with a recording/playback length of up to 66 minutes: Align the cassette with the center of the insertion slot, and push it in gently. Once inserted, the cassette tape is loaded automatically.
Operations Stop mode Turning on the power/inserting the cassette 1 Before proceeding to operate the unit, check that it has been connected properly. This unit must be placed on a level surface before any attempt is made to operate it. 1 2 The stop mode is established when the STOP button is pressed. The stop lamp lights, and the tape stops traveling. O In order to protect the tape, the tape protection mode is established after the time set in setup menu item No.400 “STILL TIMER” has elapsed.
Operations O When PB has been selected as the setup menu item No.105 setting, it will take two to three seconds for recording to commence after the REC and PLAY buttons have been pressed. (See page 30) Set this menu item to REC to start the recording faster. However, with REC set for this item, it takes longer for the image to appear during playback after the PLAY button is pressed. Recording 1 2 3 4 5 6 Use the setup menu item No.007 to select recording in either the 50 Mbps mode or 25 Mbps mode.

Regular playback now commences. Fast forward To end playback, press the STOP button. The unit is now set to the stop mode.
Operations Variable speed playback a speed playback Linear 0.3a (When AJ-A95P is connected) Pressing the SEARCH button when in play pause status causes the mode to switch to slow still. In this status, pressing the FF button or REW button causes operation to switch to linear 0.3a playback. Pressing the PAUSE/STILL button during linear 0.3a playback causes the tape to pause. Pressing the PAUSE/STILL button a second time causes linear 0.3a playback to resume.
Operations Audio channels The DVCPRO (25 Mbps) format has 2 audio channels whereas the DVCPRO 50 (50 Mbps) format has 4 audio channels. However, this unit uses only two of the channels provided with the DVCPRO 50 (50 Mbps) format. The settings for setup menu items No.711 and 712 are used to select recording or playback in the 50 Mbps or 25 Mbps mode.

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. OBefore proceeding to eject the tape manually, you must first turn off the power to the unit. 1 Remove the top panel. 4 Once more use the Phillips head screwdriver to push in and turn the red plastic screw part counterclockwise.
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 enhance the unit’s reliability, it is recommended that the video heads be cleaned every day. Use a cleaning fluid designated by the unit’s manufacturer. Condensation The same principle by which droplets of water form on a window pane of a heated room is responsible for the formation of condensation inside the unit.
