Sampling Rate - Alesis ADAT Reference Manual

devices such as digital audio tape recorders, mixing consoles, etc. Alesis's multi-
channel interface is proprietary and does not work directly with MADI devices.
Oversampling
The process of taking more samples than is required in order to more accurately
reconstruct a digitized signal back into analog.
Punching
The process of entering and/or exiting the record function while the tape is playing.
This allows recording over specific pieces of tape, such as recording over a section
with bad notes, as opposed to recording over the entire length of a track.
Rotary Head
A type of tape head, as used in ADAT, that spins at a high rate of speed in order to
create the same effect as having the tape moving by at rates not physically possible
with today's tapes and transports.

Sampling Rate

The rate at which an analog (real world) signal is converted into digital numeric
values. ADAT samples its input signals 48,000 times a second for extremely
accurate encoding.
S/PDIF Interface
Similar to the AES/EBU interface, but created by Sony and Philips with consumer
applications in mind. The optional ADAT AI-1 AES/EBU Interface offers both the
consumer S/PDIF interface and professional AES/EBU format.
S-VHS
Acronym for Super Video Home System, an improved version of VHS with greater
resolution and dubbing capabilities, as well as improved sound.
Unbalanced Audio Signals
Signals that are carried on two-conductor cables, one "hot" and one ground.
Unbalanced connections save costs, but are more prone to picking up hum and
interference with low-level signals.
