3 - System-wide options-DIGITAL screens MIDI IN MTC This refers to any MIDI Timecode received at the MIDI IN jack. If this option is selected, MTC is shown on the top right of the DM-24 display. INT. This refers to the DM-24's own internal (MIDI Timecode) generator. NOTE The internal timecode generator is not functional in this release of the DM-24 software. It will be implemented in a future release, and appropriate documentation concerning its use will be provided at that time. If the internal generator is chosen, the frame type can be selected from the following list: 30DF (30 fps drop-frame), 30NDF (30 fps non-drop), 29.97DF (29.97 fps drop-frame), 29.97NDF (29.97 fps non-drop), 25 (25 fps) and 24 (24fps). If this option is selected, INT is shown on the top right of the DM-24 display. If the internal frame type is changed, then an automatic calculation is performed to convert the old frame type as accurately as possible to the new frame rate. For instance, if the frame type is 24 fps and the DIGITAL screens The DIGITAL screens contain a number of different parameters affecting the digital audio operation of the DM-24. There are three screens: the CLOCK screen, where the digital clock source is selected, the FORMAT screen, which provides facilities for controlling the format of digital data transmitted from and received by the CLOCK settings This screen allows the viewing and selection of digital audio clocks from devices connected to the DM-24. current frame position is set to 12 (that is, halfway through a second), if the frame type is changed to 30 fps the frame position will be set to 15 (again, halfway through a second). NOTE When external timecode sources are used, the frame type is automatically recognized. INT. START TIME If the internal generator is selected as the timecode source, then the PODs are used to set the generator start time. Move the cursor so that the time is surrounded by an on-screen box, and then use the four PODs to set the hours, minutes, seconds and frames of the generator start time. FLY WHEEL (frames) If an external timecode source is selected, then it is possible to compensate for loss of incoming signal, allowing the DM-24 to "flywheel" for a set number of frames before it reports the loss of incoming timecode. The values available here are 8, 16 and 32 frames (the length of a frame depends on the frame type being received). DM-24, and the SLOT screen, to control any optional cards fitted in the slots. NOTE There should be one, and only one, word clock source in a digital audio setup. Multiple word clocks in a setup may result in noise which can damage monitoring equipment (speakers and amplifiers). Use the cursor keys or dial to move around the screen, and the ENTER key to make selections. Depending on the current assignments, the screen may change a little from that shown here. For example, if ADAT has not been selected as a return source, then it will not be shown in the appropriate position. If slot cards are not fitted, they will not appear on this screen, but if they are fitted, the SLOT fields to the left of the screen are filled, and show the slot cards currently fitted. The condition of a master clock status is shown using symbols. If the right clock is not available, or if the clock is out of the permissible limits, an appropriate symbol (cross or question mark) is shown. 24 TASCAM DM-24 Reference Manual
