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 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. 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. As the tape is loaded and threaded, the tape counter shows --LoAD--. 3 Press the FORMAT/Fs key. If you do not press the FORMAT/Fs key twice within five seconds, the indicator goes out. This is a feature designed to stop you formatting a tape accidentally. NOTE 2 Press REW to take the tape to the beginning. [. . . ] Fasten the board in place using the screws which retained the board removed in step 3. Replace the DS-D98 in the rack, reconnect the other equipment (including the analog connections) and reconnect the power. 7 8 SYNC BRANCH functions The DS-D98 introduces a new concept for slave units: branching. Using the SYNC BRANCH connector, connected to the REMOTE IN/ SYNC IN of another DS-D98 unit, or any other TASCAM DTRS unit, one DS-D98 can be used to control up 15 other such branch units. 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. [. . . ]
