The Digital Audio Stationary Head or DASH standard was a digital audio tape format using open reels capable of recording 8, 16, 24 or more channels of audio on a one-inch or half-inch tape. The data is recorded on the tape linearly, with a stationary recording head, as opposed to in the DAT format, where data is recorded helically with a rotating head. The audio data is encoded as linear PCM with strong burst error correction, allowing the tape to by physically edited, e.g. by cutting and splicing, and played back with no loss of signal.

Pulse-code modulation (PCM) is a digital representation of an analog signal where the magnitude of the signal is sampled regularly at uniform intervals, then quantized to a series of symbols in a digital (usually binary) code. ...

The DASH format also allowed the recording of low-quality cue tracks out-of-band from the program material. Out-of-band signaling is telecommunication signaling (exchange of information in order to control a telephone call) that is done on a channel that is dedicated for the purpose and separate from the channels used for the telephone call. ...
