About the DA-45HR

The Tascam DA-45HR is a professional 3U rack-mountable digital audio tape deck introduced in 1999, notable for being the first DAT recorder to support 24-bit high-resolution recording. It records 24-bit stereo audio at double the normal tape speed (16.3 mm/s) and also supports standard 16-bit DAT recording at normal speed (8.15 mm/s), providing backward compatibility with other DAT machines. The unit features balanced XLR and unbalanced RCA analog inputs and outputs, AES/EBU and SPDIF digital I/O, and Word Clock In/Thru for synchronization in digital studio setups. It includes advanced functions such as track naming, locate points, single and loop play, selectable SCMS status, and calibrated input/output controls. An optional wired remote (RC-D45) is available for convenient control. The DA-45HR is designed for professional studios and mastering houses, offering high fidelity with 24-bit A/D conversion and 20-bit D/A conversion, a signal-to-noise ratio of 105 dB, dynamic range of 105 dB, and very low total harmonic distortion (0.004%). Its robust transport mechanism runs the head drum at 2000 rpm in standard mode and 4000 rpm in high-resolution mode. The machine is praised for its excellent digital interfacing, fast and quiet transport, and comprehensive operational features, though the doubled tape speed halves maximum recording time and the D/A converter is 20-bit. It remains a reliable and versatile solution for high-quality digital audio recording and playback.
