Brooks Cinema Projectors Digital Recording
1) ADAM : (Akai Digital Audio Multitrack). 12 track recording onto Video 8 tape. 16 bit, 44.1 or 48 kHz sampling rate.
2) DAT (Digital Audio Tape) Cassette-like system which has much higher quality than standard audio cassettes. Widely used in gathering sound effects, for news gathering, and for playback of music.
3) DCC (Digital Compact Cassette) Rival to DAT which also plays standard audio cassettes.
4) MiniDisc : Uses computer disk technology, rather than tape. A laser heats an area of magnetic disk which is then written to by a magnetic head. When cooled, the magnetic information is read from the disk by laser. Tracks can be named, and are instant start. Very theatre-friendly system.
5) Direct to Disk : Uses the hard disk present in most PCs as the recording medium.

Infinite Repeat
A function on some delay lines that establish enough feedback so that the repeat echo will last forever, but not so much as to cause a howling sound.

Balance
