BNO Acoustics Speakers Auxiliary Equipment

Effects devices separate from but working with the recording console.

Expander
A device that causes expansion of the audio signal.

BNO Acoustics TS-10 Cycles Per Second
A unit used in the measure of frequency, equivalent to Hertz. Cycles Per Second is an outdated term replaced by Hertz in 1948.

Input Monitor
A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. In this mode, the tape machine's meter will read the input signal.

BNO Acoustics XV-16 Active Crossover
Uses active devices (transistors, IC's, tubes) and some form of power supply to operate.

Amplitude
The extreme range of a signal. Usually measured from the average to the extreme.

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 Baffle
A baffle so large that the sounds coming from one side do not reach the other side.
