Technical Documentation PRODUCT OVERVIEW
TASCAM's DA-302 is the world's only dual well DAT recorder. The DA-302 offers all the functionality of two DATs with the ability to make two masters of a single tape, copy from one DAT well to the other, or the ability to play on one DAT while recording the other. However, other functions are available that never existed before (or required lots of extra gear) like 2x DAT dubbing, extended play between both decks, and cascading of multiple DA-302s for duplication or playback. No major studio, dup house or live venue should be without a DA-302.

APPLICATIONS

DAT tapes have been a standard transfer medium in the professional audio industry since the introduction of the format. DAT is the only true non-compressed digital audio format that was intended to be a target writing media. The simple flexibility and worry-free operation of DAT recorders contributed to the initial rise of the format, and continues to support it in all levels of recording. The DAT format also supports deeper levels of recording flexibility. Multiple sample rates can be used, ranging from the long play 32kHz, to the CD standard 44.1kHz, to 48kHz for higher quality. Plus, the DAT tapes are reasonably inexpensive and offer up to 2 hours (4 hours in LP mode) of uninterrupted audio. TASCAM is the leading manufacturer in professional DAT recorders. The DA-302 continues the proud tradition of excellence in studio and production DAT recorders. Studios (Any Level) When you mix down a DAT, how do you make archival or distribution copies? You can either get two DAT recorders, or you can get the DA-302. The fact that the DA-302 offers high speed dubbing also allows you to save valuable time in the production schedule. For higher end users who are using 24 bit DAT or time code DATs, the DA-302 can also duplicate those. (The DA-302 cannot play a 24 bit DAT, but it can duplicate it directly across.) Live Recordings - One Man Show - Logging Functions The DA-302 offers a number of possibilities in extended play applications. If the decks are set to record in cascade from one deck to the other while in long play mode, the two DAT wells will offer 8 hours of unattended recording time. For live recordings, the regular speeds could be used for a live to 2 track mix, or a steady feed from a buss output for back-up functions. In the one man show application, the entertainer could have background tracks playing from one well, and the other well could be recording the whole performance. Or, one DAT could be playing while the other is cued up.

Section 7 : Recording/editing of subcode data

7-1. Subcode data

Recordable subcode data is shown below. Start ID (recording time: 9 seconds*) Skip ID (recording time: 1 second*) End ID (recording time: 9 seconds*) Program number (recording time: 9 seconds*) ABS time Program time (recording time: 9 seconds*) * Standard mode. Long Play recording time is twice that in the Standard mode. The detection level can be adjusted to suit the recording source. (1) While holding the SHIFT key pressed, press the AUTO ID key as many times as necessary to select the desired level (-36 dB, -42 dB, -48 dB, -54 dB, dd*). (2) Release the SHIFT key to determine the level. * When "dd" is selected, the ID is recorded by using information from the digital signal interface (SPDIF) input from the digital input connector. When a DAT deck is connected to the digital input connector, Start IDs and Skip IDs are recorded corresponding to the Start IDs and Skip IDs recorded on the DAT. When a CD player is connected to the digital input connector, Start IDs are recorded corresponding to the track numbers on the CD. When a unit other than a DAT deck or a CD player is connected to the digital input connector or analog input connectors, the "-54 dB" setting is used. 7-2-2. Recording the Start ID manually Manual recording on the fly

7-2. Start ID

A Start ID is code recorded at the beginning of each newly recorded program and is used to locate the beginning of that program during search. Start IDs can be recorded automatically or manually. Note: Be sure to leave at least 9 seconds between Start IDs. If the time between Start IDs is less than 9 seconds, a malfunction may occur during search. It is recommended to leave 30 seconds or more to ensure proper operation.

ation is recorded.
Free: The ID (00) permitting copy is recorded.
For digital-to-digital copying with an SCMS (Serial Copy Management System) deck, see below.
When ID (10) is recorded:
When either Deck 1 or Deck 2 plays back the tape, the playback signal is output from the ANALOG CASCADE OUTPUT and DIGITAL CASCADE OUTPUT connectors. When both Decks 1 and 2 are playing back tapes, the sound from the deck which entered the Play mode most recently is output. To output the sound from another deck, press the PLAY key of another deck in the Play mode. In other cases, the output signals are the same as that output when set to Input. Loop Can be set only for the master deck. When this is set to "On" with the UP/DOWN key, the master deck starts operation again after the last slave deck finishes the operation for continuous recording/playback using more than one DA-302.
A digital-to-digital copy is impossible.
When ID (11) is recorded:
One digital-to-digital copy is possible.
When ID (00) is recorded:
Multiple-generation digital-to-digital copying is possible.
