Brooks RM 909 reviews Analog Recording

A recording of the continuous changes of an audio waveform.

Console
A set of controls and their housing, which control all signals necessary for recording and mixing.

Brooks RM 909 Centre Frequency
The frequency of the audio signal that is boosted or attenuated most by an equalizer with a peak equalization curve.

Icon
A visual picture or symbol on a computer screen that represents a file, program or disc that can be used.

Brooks Hi Fi speakers 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.

Analog To Digital Converter
The device which does the conversion of a quantity that has continuous changes (usually of voltage) into numbers that approximate those changes.

Comb Filter
1) The frequency response achieved by mixing a direct signal with a delayed signal of equal strength especially at short delays.
2) Loosely used to also describe effects that can be achieved with comb filtering as part of the processing.

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 loudspeaker components.
