Recording Tricks: Tascam DA-45HR 24 bit DAT Recorder

Tascam DA-45HR 24 bit DAT Recorder

The DA-45HR is the first 24-bit DAT recorder. It achieves this storage capacity on a standard DAT tape by increasing the speed of the tape significantly (roughly double 16 bit speed).


  • Software update to fix time readout

In the first software version, the time did not display correctly when in "24 bit (high Resolution)" mode. A new sofware version (chip upgrade) fixes this. Make sure that the display shows an asterix (*) next to the ABS time readout, or it will not be "real time." This is selectable as a standard menu item.

  • Word clock dropout

A bug discovered in 2000 involves using the DA-45 with external converters. In some decks, the word clock output is inturrupted at mode changes (stop, rew, etc). This can cause a loud "pop" when the external converter loses its clock source. As of 4/2000, this was still being worked out.
