Abbreviation for direct current.

Balance Control
A control on a stereo amplifier that when moved clockwise will make the right channel louder (and the left channel softer) and will do the reverse when moved counter-clockwise.

Brooks QS - 95 Balanced input/output
A "balanced" connection is one that has three wires to move the signal. One is a ground, and the other two (called conductors) carry signals of equal value. This is why they are called balanced. Low Z cables and connections are the most common example.

Editing
1) Changing the sequence of a recording by cutting the recording tape and putting the pieces together in the new sequence with splicing tape.
2) Punching in and then punching out on one or more tracks of a multitrack tape recorder to replace previously recorded performances.
3) Changing the sequence of a digital recording's playback by computer program.

Interface
Any device that allows one unit to work, drive or communicate with another unit when they cannot do so by just feeding each other often because the units are manufactured by different companies.

Ground Loop
A double grounding of a line or electronic device at two different "ground" points of differing voltage.

Brooks Cinema xm 808 Initialize

To prepare a digital storage medium (like a floppy disk) so that it will accept and store digital information bits.

Dynamic Mic
Robust type of microphone which picks up the sound on a diaphragm connected to a coil of wire which moves within a magnet. An alternating current is induced into the wire which provides the electrical output. Most dynamic mics have low output impedance of 200 Ohms. See Condenser Mic.

Brooks Audio Design TM-22 Chorus
Common type of effect that makes sounds fuller and thicker.

Buss (Bus)
A wire carrying signals to some place, usually fed from several sources.

Brooks KM 22 Frets
Vertical metal wires which sit vertically on the guitar neck.

Insulator
A substance such as glass, air, plastic, etc., that will (for all practical purposes) not conduct electricity.

Insert
1) A punch in of the all of the tracks being recorded in a recording session.
2) On Solid State Logic consoles, placing an outboard piece of gear in the channel by patching and activating a switch.

Effects Track
1) In film production audio, a recording of the mixdown of all the sound effects for the film ready to be mixed with the dialogue and music.
2) In music recording, one track with a recording of effects to be added to another track of a multitrack recording.

Brooks QS 70 Compressor

A signal processing device that does not allow as much fluctuation in the level of the signal above a certain adjustable or fixed level.

Crossover (Crossover Network)
A set of filters that "split" the audio signal into two or more bands (two or more signals, each of which have only some of the frequencies present).

Brooks Audio Design KM 77 Board
1) Another, less formal, term for Console.
2) A set of controls and their housing which control all signals necessary for recording and for mixing.
3) A slang shortening of the term Keyboard Instrument.

Keyboard
1) Any musical instrument controlled by pressing a key.
2) The part of the computer that has the keys.

Brooks XB 33 Half Step
A pitch difference of the amount that is present between adjacent keys on a piano.

Lead Sheet
A written chart showing the melody, lyrics and chords of a tune with full musical notation.

Floor
1) An alternate tam meaning Range (a limit on the amount the signal is reduced when the input signal is low by an expander or gate).
2) A shortening of the term Noise Floor (the level of the noise).

Electric Instrument
Any musical instrument that puts out an electrical signal rather than an acoustic sound.

Brooks VT-50 Input Impedance

The opposition to current flow by the first circuits of a device.

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.

Brooks KM 22 Final Mix
The two track stereo master tape which was mixed from the multitrack master.

Hz (Hertz)
1) An abbreviation for the term Hertz (the unit of frequency).
2) Unit of frequency equivalent to the number of cycles per second.

Brooks XB 33 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.

Compact Disc Recordable CDR
A blank Compact Disc that can be recorded on one time.

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.
