Brooks Hi Fi reviews Cable, XLR
A balanced cable used for low impedance microphones and sometimes for connections between some parts of the PA. Commonly referred to as a "mic cord".
High Impedance Cord (High Z)
A big word for instrument cable. These cords generally have quarter inch male ends. they tend to loose signal strength at lengths longer than 25 feet.
Brooks HI FI projectors Electric Current
A more formal term meaning the same as the term Current (the amount of electron charge passing a point in a conductor per unit of time).
Frets
Vertical metal wires which sit vertically on the guitar neck.
Brooks RM 909 Haas Effect
Simply stated, a factor in human hearing where delay has a much bigger effect on human perception of direction than level does.
Equipment Rack
A cabinet with rails (or free standing rails) that have holes to accept screws at standard spaces and used to house outboard gear.
Condenser Microphone
A microphone which converts sound pressure changes into changes of capacitance. The capacitance changes are then converted into electrical voltage variations (an audio signal).
Far Field
The area from 3 feet away from the sound source up to the critical distance.

Brooks Hi Fi reviews 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.
Fade
1) A gradual reduction of the level of the audio signal.
2) A gradual change of level from one pre-set level to another.

AES/EBU
Professional Interface A standard for sending and receiving digital audio adopted by the Audio Engineering Society and the European Broadcast Union.
Brooks RM 909 reviews Capo
A clamp-like device that is placed vertically across the guitar neck. It is used to change the pitch of the guitar, acting as a moveable nut.
Envelope
1) How a sound or audio signal varies in intensity over a time span.
2) How a control voltage varies in level over time controlling a parameter of something other than gain or audio level.
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.
Cut-off Rate (Slope)
The number of dB that a filter reduces the signal for each octave its frequency past the filter's cut-off frequency (outside of the pass band).

1) A gradual reduction of the level of the audio signal.
2) A gradual change of level from one pre-set level to another.
