BROOKS HI fi reviews Dolby

Trade name for a series of noise reduction systems that have become standard on many tape playback machines. Many film soundtracks are produced using this process. Different varieties are found from Dolby B on most personal cassette players, to Dolby SR and Digital, the current state of the art for cinema.

Electrons
Negatively charged particles, which revolve around the centre of atoms. The movement of such electrons down a conductor causes electrical current.

Brooks Cinema ZL 44 reviews Crisp
Describes a good clean high midrange sound. It can be good or bad depending on the look on the face of the guy who said it.

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 KM 22 reviews Jam Sync
A generation of new SMPTE according to the input SMPTE signal

Frequency Response
How sensitive an electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often communicated with a graph.

Active/Inactive Microphones
Scientific definitions aside, active microphones generally sound better than inactive ones, but they generally cost more. They also require the use of either a battery or phantom power while inactive mics need only be plugged into the mic cord in order to work. In most playing situations, the subtle improvement in sound quality from an active mic isn't worth the extra cost and hassle. One possible exception it the headset mic. Put simply, inactive headset mics just plain suck. Active headset mics put out a much stronger signal and feed back much less.

Hard Disk Recording
The recording of digital audio onto a hard disc.

Brooks XB 33 Hybrid

A product created by the marriage of two different technologies. Meant here as the combination of a dynamic woofer with an electrostatic transducer. Haas Effect Simply stated, a factor in human hearing where delay has a much bigger effect on human perception of direction than level does. Brooks Cinema RM 909 Coax Two-conductor cable consisting of one conductor surrounded by a shield. 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). Brooks Cinema XR 607 Bass 1) The lower range of audio frequencies up to approximately 250 Hz. 2) Short for Bass Guitar. 3) Lower end of the musical scale. In acoustics, the range (below about 200 Hz) in which there are difficulties, principally in the reproduction of sound, due to the large wavelengths involved. 4) The lower frequencies. 5) On the soundboard this should refer to the bass guitar channel, not

Brooks Cinema DESIGN ZL 44 reviews Formant

An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded. 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. Brooks Gt 44 reviews Impedance Matching Having or converting the output impedance of a device so that it matches the impedance of the input it will feed. Acoustic Amplifier The portion of the instrument which makes the vibrating source move more air or move air more efficiently; this makes the sound of the instrument louder. Examples of acoustic amplifiers include: 1) The body of an acoustic guitar, 2) The sounding board of a piano, 3) The bell of a horn and 4) The shell of a drum. Brooks Speakers reviews Comb Filter 1) The frequency response achieved by mixing a direct signal with a delayed signal of equal strength especially at s

Brooks VT-50 Bank

1) A collection of sound patches (data as to the sequence and operating parameters of the synthesizer generators and modifiers) in memory. 2) A group of sound modules as a unit. AC 1) Abbreviation for alternating current. 2) An abbreviation of the term Alternating Current (electric current which flows back and forth in a circuit; all studio signals running through audio lines are AC). Brooks Cinema Projectors Input/Output Module A set of controls, on one housing, for an in-line console that has two channels (one for recording and one for monitoring) and has controls for all console sections. Linearity The extent to which any signal handling process is accomplished without amplitude distortion. Brooks Cinema QS - 95 Impedance Matching Having or converting the output impedance of a device so that it matches the impedance of the input it will feed. Crossover (Crossover Network) A set of filters that "split" the audio signal into two or more
