[. . . ] CAUTION Changes or modifications to this equipment not expressly approved by TEAC CORPORATION for compliance could void the user's authority to operate this equipment. For the consumers in Europe WARNING This is a Class A product. In a domestic environment, this product may cause radio interference in which case the user may be required to take adequate measures. Pour les utilisateurs en Europe AVERTISSEMENT Il s'agit d'un produit de Classe A. Dans un environnement domestique, cet appareil peut provoquer des interférences radio, dans ce cas l'utilisateur peut être amené à prendre des mesures appropriées. [. . . ] If the display shows something other than 00:00:00:00, this means that the tape is now at a position other than the point where you captured the time (i. e. the tape was playing or recording). 6. 4 ABS setting The ABS setting allows you to use the subcode on the servo track of the DTRS unit as the time reference of the 246. Usually, this starts at 00:00:00:00, and continues for the length of the tape. However, there are some options available with the ABS mode, which increase the flexibility of the system. These are described in 8. 1. 2, "Synthesizing timecode from ABS times", and allow you to start with an offset, etc. when synsthesizing timecode. All times now are relative to this time. Any locations will now be shown on the TAPE TIME display relative to the new 00 memory. For example, if the relative "zero point" is set to 00:30:00:00, when the tape is at the absolute location of 00:45:00:00, the value shown on the TAPE TIME display will be 00:15:00:00 (45 ­ 30). However, even though the value shown on the TAPE TIME display changes, neither the actual tape position nor values shown on the LOCATE TIME/VALUE display are affected. Absolute settings 6. 4. 1 A note on ABS frame rate When ABS is selected, the number of frames per second is different from that in any timecode mode. For details of setting SMPTE/EBU frame rates, see 8. 1. 3, "Selecting a timecode type". Timecode (whether SMPTE or EBU) contains a fixed number of frames per second. We therefore suggest that you do not use location memory 00 as a general location point. NOTE Location memories stored on the 246 are completely independent of either the MEMO 1 and MEMO 2 points stored in the DTRS units, or of the 10 extra memory locations which may be stored in a DA-98 unit. 6. 5. 4 Manual entry of a location point You can also use the numeric keypad to enter a time value manually from a cue list, etc. Time values are entered from the right of the display, which is cleared as soon as a number key is pressed. For instance, to enter a value of 01:25:34:12, the following keys should be pressed: 00:00:00:01 (display is cleared and starts flashing) 2 00:00:00:12 5 00:00:01:25 3 00:00:12:53 4 00:01:25:34 1 00:12:53:41 2 01:25:34:12 ENTER/LOAD (stops display flashing and enters the value) 1 1) Enter or capture a location time (you do not need to press ENTER in this case). 2) Press the STR key [17]. Note that the ENTER/LOAD key [20] is used to confirm the entry. If you make a mistake entering the value, you can stop the entry procedure with the CANCEL key [19]. This time value can now be used for "instant" location (simply press the LOC key [41]) or stored in a location memory for further use (see 6. 5. 6, "Storing the location in a memory"). The LOCATE TIME/VALUE display will stop flashing, and the MEMORY NO. display [14] will start to flash. 3) Use the numeric keypad [16] to enter the number of the location memory into which you want to store the value. The number will "fill up" from the right. If you want to store the time value in memory 03, for example, you only need to press the 3 key, but if you want to store it in memory 13, press the 1 key, followed by the 3 key. You can also use the JOG dial as a data dial (when the DATA INC/DEC indicator [27] is lit) to select the location memory. 6. 5. 5 Editing a location When a location has been captured or entered as described above, it can be edited using the jog dial [28]. 1) Ensure that the DATA INC/DEC indicator [27] is lit. If this indicator is not lit, the JOG dial will control the tape transport. 4) Press the ENTER/LOAD key [20]. The MEMORY NO. display will stop flashing, and the value is stored in the location memory. 2) Use the JOG dial to adjust the value of the location point. [. . . ] Analog track 3 in the controller mapping is traditionally used as the timecode track. To map this track to the audio track selected above (see 9. 4. 2, "Track mapping functions") or to the dedicated timecode track of the DA-98: 98 See section 11. 1. 2 of the DA-98 manual for full details regarding this function. 1) From menu group 6, move the cursor to Eml Dev (emulation device) and press SELECT: Emulation Device 1 1) From menu group 6, move the cursor to TC Rec EN, and press SELECT: TC Record Enable Machine enable disable Machine » 1 » 2 » 3 » 4 » 5 » 6 PCM-7050 2) Use the UP and DOWN keys to select the appropriate setting for each connected DTRS unit. Selecting disable here means that the track referred to by the controller's commands as "analog 3" will be the DTRS track designated as "analog 3" in the table above (9. 4. 2, "Track mapping functions"). Selecting enable means that the DA-98's dedicated timecode track will be controlled by commands addressed by the controller to the "analog 3" track. 2) Use the UP and DOWN keys to select the device to be emulated from the following list: · · · · · · · · PCM-7050 BVH-3000 BVU-950 BVW-75 PCM-800 BVH-2000 DVR-10 TASCAM TASCAM is the native format of the DA-98, and should be selected if you do not need to emulate any other device from this list. 9. 4. 4 Remote track arming 98 It is sometimes useful to be able to disable track arming of a DA-98 unit from a remote controller, especially when that controller is a video editor which only allows for the arming and con- 9. 4. 6 Recording delay When a DA-98 is remotely controlled by an editor, it is sometimes useful to be able to program a delay in recording, in order to emulate a VCR, 98 9-5 Section 9. 4 - Other DTRS control functions which typically begins recording a few frames after the command is received from the editor (the DA-98 begins recording immediately).
