[. . . ] D00635720A DS-D98 Digital Multitrack Recorder OWNER'S MANUAL Ü ÿ Y This appliance has a serial number located on the rear panel. Please record the model number and serial number and retain them for your records. Model number Serial number CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. [. . . ] 24) Heat -- The product should be situated away from heat sources such as radiators, heat registers, stoves, or other products (including amplifiers) that produce heat. TASCAM DS-D98 3 DS-D98 recorder The DS-D98 recorder provides the facility to record using the Direct Stream Digital (DSD) digital audio representation, as employed by the Super Audio CD format, using the convenient industry standard DTRS digital multitrack medium. Based around the DA-98HR recorder, the DS-D98 has many features in common with its "parent" unit. PCM recordings made on this unit can be replayed on other DTRS units (subject to the sampling frequency and word length restrictions of the other units) and PCM recordings made on other DTRS units can be replayed on the DS-D98. Please read the relevant portions of the DA-98HR manual, as supplied, in order to gain a full understanding of the basic operations of this unit. The main differences between the DS-D98 recorder in DSD mode and the PCM digital audio mode (in which it acts in the same way as a DA-98HR recorder) are: · The recording format and input sources. In DSD mode, the DS-D98 uses digital audio I/O in SDIF-3 or DSD raw audio format or the analog connectors fitted to the DSD slot board (compared with the TDIF and AES/EBU interfaces of the standard DA98HR). In DSD mode, these standard TDIF and AES/EBU interfaces are not used. In PCM mode, the DS-D98 is capable of recording eight, four or two tracks of PCM digital data, depending on the sampling frequency selected. The exact signals being monitored depend on the transport status and the status of the INPUT MONITOR of the tracks as well as the confidence 6 ANALOG INPUTS (1, 2) This pair of balanced XLR-type connectors is used for the input of analog audio. 7 ANALOG OUTPUTS (1, 2) This pair of balanced XLR-type connectors is used for the output of analog audio. TASCAM DS-D98 - 5 DS-D98 recorder The exact signals being monitored depend on the transport status and the status of the INPUT MONITOR of the tracks as well as the confidence mode. See 5, "Monitoring modes" of the DA-98HR manual for full details of monitoring modes. NOTE Unbalanced equipment should not be connected to the analog input or output connectors. Since the metering is performed using a 44. 1kHz PCM conversion, the levels of signals which have a frequency of more than 20kHz are not shown on the meters. These analog connectors (input and output) are wired according to the usual standard: 1=ground, 2=hot, 3=cold. DSD mode Whenever a tape is formatted in the DS-D98 in DSD mode (see below), or a tape previously formatted in DSD mode is inserted, the unit enters DSD mode. In DSD mode, the AVAILABLE TRACK indicators for tracks 1 and 2 (0) light green, also showing that DSD mode has been selected. When the unit is in DSD mode, the explanations given in this document apply. When a DSD-formatted tape is ejected and a standard PCM DTRS tape is inserted (or a blank tape is formatted in PCM mode), the unit reverts to PCM mode. In DSD mode, only 44. 1kHz-based sampling frequencies may be used. 48kHz sampling frequencies are invalid in this format. However, the sampling frequency indicators to the right of the tape counter do not light in DSD mode. If pull-up or pull-down Fs shift is enabled (9. 4. 1, "Pull up and pull down (Fs shift)", however, the PULL UP and PULL DOWN indicators light appropriately. 8 9 0 The blue DSD indicator on the front panel 8 lights to show this mode is now active. Formatting the tape As with all DTRS recorders, it is necessary to format a tape before using it in the DS-D98 recorder. See 6. 2, "Formatting a tape" in the main DA-98HR manual for details of how the tape is formatted. However, there is a significant addition to the options available for the DS-D98, which is the provision of the DSD mode. 1 Switch on the DS-D98 and load a tape into the tape loading slot. [. . . ] The first unit connected to the head of such a branch must be set to have a machine ID of 2, and the other branch units in the branch should have IDs following this, in order. See 8. 2, "Machine ID and master/slave settings" in the DA-98HR manual. Subsequent branch units are connected using the SYNC OUT to REMOTE IN/SYNC IN chain, as is standard with DTRS units. See 8. 1, "Synchronization connections" for details. [. . . ]
