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).
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.
