SYSTEM button. Appendix C contains information you’ll need to know when setting up your HDR24/96 for file transfers over a network.

Digital I/O

When DIO•8 or PDI•8 cards are installed in the HDR24/96 I/O slots, a pulldown menu will appear for each installed card. Setup options for each card are addressed in the Quick Start Guide and in further detail in Appendix A. The equivalent setup options are available from the front panel using the DIGI-I/O button.

Locator-MMC – Tempo Map and Tempo settings

This is a multi-function menu with functions described in detail in Appendix A. The tempo for BBT scale calculation is set from this menu. A MIDI file with a tempo map can be loaded from this Setup window, to allow the BBT display to follow tempo changes when the HDR24/96 is synchronized to a MIDI sequencer. Song Offset (page 16) and Preroll (page 37) times are set from this window, as are device ID’s for MIDI Machine Control.

Sync

This menu contains setup parameters for sample clock source and rate, bit depth, time code source and framing, activates time code output, and allows setting of time code offset. Appendix D contains detailed information about both time code and sample clock synchronization. All of these parameters can be set from the GUI menu or from the front panel using the SYNC button.

Sample Clock

Selects the source for the sample (word) clock. Choices are Internal, Word Clock (BNC), or Video (BNC). In the GUI, when Video (BNC) is selected, another pulldown menu appears for selecting Video Frame Rate. The video frame rate (Video Field) option is always present on the front panel display SYNC menu, but is only applicable when video is selected as the clock source.

Sample Rate

This pulldown GUI menu selects a sample rate of 44.1 and 48 kHz. The SELECT buttons are used to toggle the sample rate in the front panel SYNC menu.

Bit Depth

This pulldown GUI menu selects a bit depth (word length) of 16 or 24 bits. The SELECT buttons are used to toggle the Bit Depth in the front panel SYNC menu.

Time Code Source

This pulldown GUI menu selects the source of incoming time code when the HDR24/96 is set to Time Code Chase (page 37). Choices are MTC (MIDI Time Code) and SMPTE. From the front panel, Select Time Code Source from the SYNC menu, then toggle between MTC and SMPTE using the Select buttons.

Time Code Frame Rate

This pulldown GUI menu selects the frame rate for incoming time code when the HDR24/96 is set to Time Code Chase (page 37). From the front panel, Select Time Code Rate from the SYNC menu, then the Select buttons to select the frame rate.
