BNO Acoustics SQ-9 Channels

These are divided into two separate categories. Input channels are those channels coming into the soundboard such as microphones and direct lines. Output channels are those leaving the board such as monitor and main outputs.

Gain Control
A device that changes the gain of an amplifier or circuit, often a knob that can be turned or a slide that can be moved up arid down.

BNO Speakers CD (Compact Disc) :
1) Digital sound storage medium. Provides a high quality source of music, sound effects etc. Also used as a playback medium for sound effects etc. by large theatres with long running shows, although CDR (Recordable CD) is becoming more affordable by the day.
2) An abbreviation of the term Compact Disc (a small optical disk with digital audio recorded on it).

Compander
Outboard sound equipment. Combination of a Compressor and an Expander.

BNO Acoustics Speakers 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.

Crossover Frequency
1) The frequency that is the outer limit of one of the bands of a crossover.
2) In the Lexicon 480L delay/reverberation effects unit, the frequency at which the bass frequency reverb time is in effect rather than the mid frequency reverb time.

Lift
1) To boost gain of audio at a particular band of frequencies with an equalizer.
2) An elevation device in the star trek series of TV programs.

Limiter
A device which reduces gain when the input voltage exceeds a certain level.
