360 systems 2720 DIGICART II random access RECORDER 120V

You have chosen 360 systems 2720 DigiCart/II Plus, the most advanced hard disk/cart system in the broadcast industry. Building on technology proven in the industry-standard DigiCart/II, your new DigiCart/II Plus delivers many significant enhancements. A few of these enhancements include the use of low-cost removable Iomega Zip™ disks, larger hard disks, and the inclusion of the D-Net file transfer network as standard.

Cuts are stored on an internal fixed hard disk drive (HDD) or removable Zip™ disks. Each

DigiCart/II Plus contains an internal hard drive and Zip drive.

Transportable recordings for archiving and backup are stored on Iomega Zip disks. These economical, re-recordable compact magnetic disks are DigiCart/II Plus's "carts". Iomega, the company that built the reliable Bernoulli™ drive used in the legendary DigiCart/II, has engineered the Zip drive system to provide the speed, ease of use and reliability required in professional audio. Each Zip disk can store 100MB of data - enough to record 8¾ minutes of 16-bit linear stereo at 48k, and 9½ minutes at 44.1k.

A notable feature of DigiCart/II Plus is selectable recording formats. You may choose linear sampling rates of 48, 44.1 or 32 kilo samples/second in mono or stereo. All formats can coexist, for the machine is smart and plays them back automatically. Dolby AC-2 stereo data compression is selectable at the 48k rate. AC-2 delivers more than five times as much stereo storage time with subjectively excellent sound quality. Accurate compression and expansion of digital information accomplish this. AC-2 does not use "psycho-acoustic tricks" that discard parts of the sound that might not be noticed.

DigiCart/II Plus's storage space is variable. By matching bandwidth and track needs to the material (or limits of the downstream audio chain) you may maximize storage. These flexible rates provide advantages for the broadest range of applications. For most applications, Dolby AC-2 delivers the greatest broadband storage without regard to content. AC-2 uses less disk space than even 32k mono recording while delivering full-bandwidth stereo.

Because DigiCart/II Plus is a software-based device, supplementary information can be stored along with each individual audio recording. This information is stored in a header containing:

  • Five-character ID for drive, directory and cut.
  • A name of up to fifteen alphanumeric characters
  • Total running time
  • Sampling rate
  • Recording format
  • Editing information for head and tail times, fade in, fade out, gain, and secondary cue timing.

Much of this information is displayed on the front panel of your DigiCart/II Plus to assist you in managing a large audio library.

A significant advantage of DigiCart/II Plus is random access to any cut. Multiple drives, directories, and cuts are quickly accessed. Once the ID of a cut appears in DigiCart/II Plus's display, that cut is pre-loaded and available for instant playback. This way, multiple sequential cuts can be rapidly accessed from a single DigiCart/II Plus machine. Unlimited cuts may be stacked in easily edited

pre-built lists. The Quickstack™ feature lets you create a sequence "on the fly" for one-time-only use, or it may be saved and named for repeated use.

DigiCart/II Plus also expands the traditional role of the cart machine by including non-destructive editing capabilities. You edit and prepare cuts on the same medium used for playback. Start and endpoints are easily adjusted. Up to 40 seconds of fade-in and fade-out can be applied. Playback gain can be set for each individual recording and sounds may be seamlessly looped for continuous play.

Maintenance issues have been addressed with modular construction, making repairs an easy matter for the electronics professional. Durable construction keeps wear and tear to a minimum, even in high-usage environments. The design of DigiCart/II Plus incorporates built-in upgrade paths and the capability to accept larger disk drives as storage technology advances.

DigiCart/II Plus has been significantly enhanced by the inclusion of D-Net file transfer software as standard. D-Net enables the digital audio interfaces of your DigiCart/II Plus to be used faster than real-time transfers of individual cuts, entire drives, and their associated file information.

Before you begin using your DigiCart/II Plus, please take the time to read this manual. You'll find information regarding startup and a condensed operating guide with concise step-by-step instructions in Chapter 1. Chapter 2 covers setup. Detailed operating instructions are in Chapter 3. stacks (playlists) are explained in Chapter 4. Maintenance information is contained in Chapter 5. The operation of D-Net is detailed in Chapter 6.
