Brooks Audio Design

A large building designed for concerts; also called a concert hall. Layering The recording (or playing) of a musical part with of several similar sound patches playing simultaneous. Brooks Cinema XR 607 Hall Program A setting of a digital delay/reverb effects unit that approximates concert halls. Hall programs are characterized by pre-delay of up to 25 ms. Impedance 1) A term for the electrical resistance found in a/c circuits. Affects the ability of a cable to transmit low level (e.g. sound) signals over a long distance. Measured in Ohms. Speakers are rated according to power handling capabilities (Watts, W) and impedance (Ohms). 2) The total opposition offered by an electric circuit to the flow of an alternating current of a single frequency. It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker's impedance changes with frequency, it is not a constant value. 3) The opposition to alternating current. Brooks BA ...

(Said of compressors and dynamic processing units.) To combine the control input signals of two channels of a compressor (o 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. Brooks KS-55 File A collection of digital data stored in a computer's memory bank or on a floppy disc. Crossover 1) A route leading from one side of the stage to the other, out of the audiences view. 2) An electronic filter in a sound system that routes sound of the correct frequency to the correct part of the speaker system. Different speakers handle high frequencies (tweeters) and low frequencies (woofers). Sometimes known as a crossover network. An active crossover splits the signal from the mixing desk into high, mid and low frequencies which are then sent to three separate amplifiers. 3) An electrical circuit that divides a full bandwidth signal into the desired frequency bands for the lo...

A grouping of eight information bits. Consumer Format (Consumer DIF) A standard adopted by IEC for sending and receiving digital audio based on The AES Professional Interface. Brooks TM-22 Frets Vertical metal wires which sit vertically on the guitar neck. Frame 1) A division of one second in synchronization and recording coming from definition two. 2) The amount of time that one still picture is shown in film or video. Brooks Cinema NZ 60 Librarian Program A computer program allowing the storage of the parameters of sound patches outside of a synthesizer. 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). High-Pass Filter...

Sending too high of a signal level into a device so that the first amplifier of the device overloads. Audio Most often referring to electrical signals resulting from the sound pressure wave being converted into electrical energy. Brooks TM-22 Cycle 1) An alternation of a waveform which begins at a point, passes through the zero line, and ends at a point with the same value and moving in the same direction as the starting point. 2) On a Solid State Logic Console, a command to have the console computer control the tape machine to play and replay a certain section of the tape. Link (Said of compressors and dynamic processing units.) To combine the control input signals of two channels of a compressor (o Brooks Speakers Analog (Analogue) Representative, continuous changes that relate to another quantity that has a continuous change. CD (Compact Disc) : 1) Digital sound storage medium. Provides a high quality source of music, sound effects etc. Also used as...

Short for the term Auxiliary Send (a control to adjust the level of the signal sent from the console input channel to the auxiliary equipment through the aux buss. Headstock The area of the guitar at the end of the neck where the strings are tuned. Brooks XB 22 Gain 1) Knob usually found at the top of each input channel on the soundboard. Used to set input levels of the separate channels to relatively equal positions. 2) The amount of increase in audio signal strength, often expressed in dB. Effects 1) Various ways an audio signal can be modified by adding something to the signal to change the sound. 2) Short for the term Sound Effects (sounds other than dialogue, narration or music like door closings, wind, etc. added to film or video shots). Brooks KM 77 Golden Section A ratio of height to width to length of a room to achieve "good acoustics" and first recommended by the ancient Greeks. The ratio is approximately the width 1.6 times the height ...

Short for the term High Frequencies (the audio frequencies from 6000 Hz and above). Acoustic Echo Chamber A room designed with very hard, non-parallel surfaces and equipped with a speaker and microphone; dry signals from the console are fed to the speaker and the microphone will have a reverberation of these signals that can be mixed in with the dry signals at the console. Brooks Cinema TZ 505 Contact Microphone A device that senses vibrations and puts out an audio signal proportional to the vibrations. Final Mix The two track stereo master tape which was mixed from the multitrack master. Brooks Speakers Clipping Distortion of a signal by its being chopped off. An overload problem caused by pushing an amplifier beyond its capabilities. The flat-topped signal has high levels of harmonic distortion which creates heat in a loudspeaker and is the major cause of loudspeaker component failure. Bi-Directional Pattern A microphone pick up pattern which has maxim...

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. Dry Describes a sound coming from the PA with no effects on it. Brooks BA 71 Corner Frequency Same as Cut-Off Frequency (the highest or lowest frequency in the pass band of a filter). (NOUN) Cycle 1) An alternation of a waveform which begins at a point, passes through the zero line, and ends at a point with the same value and moving in the same direction as the starting point. 2) On a Solid State Logic Console, a command to have the console computer control the tape machine to play and replay a certain section of the tape. Brooks KM 77 Beats Per Minute BPM The number of steady even pulses in music occ...
