2) Unit of frequency equivalent to the number of cycles per second.

BNO Acoustics GT-60 Head
1) In tape recording, the transducer (energy converter) that changes the audio energy from electrical energy to magnetic energy and back; also the devices that apply magnetism to the recording tape for other purposes such as in the erase head.
2) The part of a device that immediately includes the transducer to change sound or audio signals from one energy form to another.

Ground Lift

Bar
A term meaning the same thing as the term Measure (the grouping of a number of beats in music, most-often four beats).

BNO Acoustics HD-70 Guitar Controller

An electric guitar or device played like an electric guitar that puts out MIDI signals that can be used to control synthesizers and sound modules.

BPM
An abbreviation of Beat Per Minute (the number of steady even pulses in music occurring in one minute and therefore defining the tempo).

BNO Speakers Key
The control of a dynamics processing device by an external audio signal.

Auxiliary Output or Send
An additional output from a sound desk that can be used for foldback or monitoring without tying up the main outputs. Each input channel will have a path to the Aux buss. Also used for feeding a signal to an effects processor. See Auxiliary Return.

BNO Acoustics QT-5 Feedback
1) The delayed signal sent back to the input of a delay line, used in repeat-echo effects.
2) The pickup of the signal out of a channel by its input or the howling sound that this produces.
3) In an amplifier, the phase reversed output signal sent back to its input, reducing gain but also distortion and noise.
4) This occurs when the sound coming out of the speakers goes back into the microphones, then back out the speakers, then back into the mics…and so on. This can build very quickly to a point where everyone in the room is holding their ears and screaming at you. It can also cause damage to the PA.

Analog Recording
A recording of the continuous changes of an audio waveform.

Compressor
1) Effect used to squash the sound together. Used properly, it can take the edge off or your sound. Used improperly, it can take the life right out of your system and make it sound like an MTV mix.
2) A piece of sound processing equipment that ensures all wanted signals are suitably placed between the noise and distortion levels of the recording medium. It evens out the unwanted changes in volume you get with close-miking, and in doing so, adds punch to the sound mix. A Limiter is used to stop a signal from exceeding a preset limit. Beyond this limit, the signal level will not increase, no matter how loud the input becomes. A Limiter is often used to protect speaker systems (and human ears) by preventing a system from becoming too loud.

Foot (Foot Drum)
Another name for Bass Drum (the largest drum in the Drum Kit which puts out bass frequencies and is played with a foot pedal).

BNO Acoustics GK-3 Chorus

1) The part of The song that is repeated and has the same music and lyrics each time; the chorus will usually give the point of the song.
2) A musical singing group that has many singers.
3) A delay effect that simulates a vocal chorus by adding several delays with a mild amount of feedback and a medium amount of depth.
4) A similar effect created in some synthesizers by detuning (reducing the pitch of, slightly) and mixing it with the signal that has regular tuning and with a slight delay.

Electromagnetic Induction or Pick Up
The generation of electrical signal in a conductor moving in a magnetic field or being close to a changing magnetic field.

BNO Acoustics HD-70 Bass Roll Off
An electrical network built into some microphones to reduce the amount of output at bass frequencies when close-micing.

Cue
1) The signal fed back to the musicians through headphones.
2) To set the tape or disc so that the intended selection will immediately play when the tape machine or player is started.
3) A location point entered into a computer controlling the playback or recording of a track or tape.
4) In MCI brand tape machines, a term meaning the same thing as Sync Playback (where the record head is used as a playback head for those tracks already recorded).

BNO Speakers AES/EBU
Professional Interface A standard for sending and receiving digital audio adopted by the Audio Engineering Society and the European Broadcast Union.

Amplifier
Sound equipment that converts the low voltage, low current signal from a tape deck, mixer etc. into a higher current signal suitable for driving speakers. See Power Amplifier, Crossover.

Equal Loudness Contours
A drawing of several curves showing how loud the tones of different frequencies would have to be played for a person to say they were of equal loudness.

ADAT
A trademark of Alesis Corporation designating its modular digital multitrack recording system released in early 1993.
