ADAT Optical interface

The ADAT Optical interface provides a unidirectional point-to-point connection of 8 tracks of 24-bit digital audio, with subcodes, at professional sampling rates, on a single consumer-grade optical fiber. A typical use is for a data connection between multiple ADAT tape decks, for bouncing tracks between decks.

AES3

The AES3-1992 specification of transmission format for digital audio data. This specification is also commonly referred to as AES/EBU. See also ANSI S4.4-1992 and IEC958 (now officially designated “IEC 60958), Audio Engineering Society, Inc., Vol. 40, No. 3, 1992, New York, NY 10165. For more information on this specification, see http://www.aes.org/publications/

AES-3id

An information document describing implementation of AES3-1992 (see above attribution) using 75-ohm coaxial cable with 1 V peak-to-peak signal levels. See http://www.aes.org/publications/

PCI

Peripheral Component Interconnect—a bus specification. The PCI bus is a high-performance local bus used to connect peripherals to memory and a microprocessor. A wide range of vendors make devices that plug into the PCI bus.

PCI I/O blank panel

A metal panel that fits on a slot in the I/O door. It must be in place if a PCI board is not installed in the corresponding slot in the PCI module.

S/PDIF

A serial interconnect standard for consumer digital audio equipment. This interface can transfer stereo or single channel audio content at sample resolutions up to 20 bits (or 24 bits using an extension to the specification) and sample rates of 32 kHz, 44.1 kHz, and 48 kHz. Physical connectors are typically RCA jacks or optical connectors. For a complete description of S/PDIF, see the IEC 958 specification (now officially designated “IEC 60958).
