TOSLINK

TOSLINK is an optical digital audio format developed by the Toshiba Corporation. These
digital audio formats can be transmitted via TOSLINK optical cables and connectors:

 S/PDIF
 ADAT Lightpipe

Some Macintosh computers have a single interface that combines a TOSLINK connector
with an analog stereo miniplug.

ADAT Lightpipe

ADAT Lightpipe is an eight-channel digital audio format developed by Alesis. This
signal format uses TOSLINK optical connectors. Eight channels are supported at sample
rates of 44.1 and 48 kHz using 24 bits per sample. Higher sample rates are available by
pairing channels (this format is sometimes called sample multiplexing, or S/MUX). For
example, a sample rate of 192 kHz is possible, but the number of channels is reduced to
two. However, not all equipment supports channel pairing and increased sample rates.

TDIF

Tascam Digital Interface (TDIF) is a signal format for transferring digital audio between
Tascam digital multitrack recorders or digital mixers. A 25-pin D-subminiature
connector is used. Eight channels are supported at sample rates of 44.1 and 48 kHz
using 24 bits per sample. Higher sample rates are available by pairing channels.
