2 Chapter 1-Welcome to the D24 Welcome to the D24 Thank you for choosing the Yamaha D24 Digital Multitrack Recorder. The D24 uses standard 3.5-inch removable MO (Magneto Optical) disks for digital audio recording and playback. By employing a removable media, backup downtime in between sessions is eliminated. When one session is complete, simply insert a new disk and begin recording right away. Random access capability provides instant access to up to 99 projects per disk, 99 locate memories per project, all without unproductive rewinding and fast forwarding. Audio data is not compressed, and superb sonic performance is achieved using 16-, 20-, or 24-bit recording resolutions and 44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz sampling rates, all of which can be set on a project-by-project basis. Overwrite-type 640 MB MO disks offer 8-track simultaneous recording, with a 24-bit recording resolution and 44.1 kHz or 48 kHz sampling rates, and 4-track simultaneous recording at the higher sampling rates of 88.2 kHz or 96 kHz. A single 640 MB MO disk provides a total recording time of 120 track minutes, or 30 minutes for 4 tracks, 15 minutes for 8 tracks. In addition to the eight main tracks, each track features up to eight virtual tracks, for a grand total of 64 tracks. Auto punch in/out recording, with multiple take capability, allows you to choose the best from up to 99 takes. Both manual and auto punch in/out recording can be rehearsed with automatic playback and input monitor switching. Video machine-like shuttle playback makes it easy to locate material, and the current position can be nudged in sub-frame steps while listening to a small section of the surrounding material. Tracks can be soloed for individual track monitoring. Other features include ±6% varispeed, A-B repeat playback, and fast forward or rewind at 8x or 16x normal playback speed. In addition to the 99 locate memories, the A, B, Last Rec In, and Last Rec Out points offer additional ways locate specific positions quickly, repeatedly, and accurately. Other quick locate functions include Project Search, Return to Zero, and Roll Back. Location points can be specified with sub-frame accuracy. Additional recording space can be made available, and projects backed up by connecting optional, external hard disk drives or removable media disk drives to the D24's SCSI port. The number of tracks available for simultaneous recording and playback can be expanded in multiples of eight by combining up to eight D24s. The total continuous recording time can be extended by using two D24s in Serial mode. The D24's 3U rack size makes it a drop-in alternative to modular digital multitrack recorders. Optional mini YGDAI (Yamaha General Digital Audio Interface) cards offer a variety of analog and digital I/O configurations, with support for all the popular digital audio interconnect formats: AES/EBU, ADAT, and Tascam TDIF-1. S/PDIF Coaxial I/O allows digital stereo transfer between 2-channel digital audio equipment, CD players, DAT decks, and mastering equipment. A front panel phones jack provides convenient monitoring. Once recorded, projects, tracks, and parts can be edited using non-destructive editing functions, such as 50% to 200% time compression and expansion, ideal for audio-fit-video applications, and pitch change without speed change. Project editing functions include Copy, Delete, Erase, Title, Protect, and Timecode Modify. Track editing functions include Copy, Move, Erase, Swap, and Slip. Part editing functions include Copy, Move, Erase, Insert Space, Insert Copy, and Delete, with single-step undo and redo. Edit points can be specified with sub-frame accuracy. D24-Owner's Manual
