Brooks Gt 44 IC

Abbreviation of Integrated Circuit (A miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment).

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

Brooks GT 845 Decibel (dB)
1) Relative measurement for the volume (loudness) of sound. Also used to measure the difference between two voltages, or two currents. See Zero dB.
2) A numerical expression of the relative loudness of a sound. The difference in decibels between two
sounds is ten times the common logarithm of the ratio of their power levels.

Amplitude
The strength of a vibrating wave; in sound, the loudness of the sound.

Brooks Cinema ZL 44 Head Amp
British name for Preamplifier (A low-noise amplifier designed to take a low-level signal, such as the output of a tape head, and bring it up to normal line level).

Hearing Limitation
An inability of the ear to hear important characteristics of sound under certain conditions. Characteristics that can be affected include pitch, level, clarity, presence and direction.

Bi-Amplification
1) A way of optimizing the efficiency of a speaker system by separately amplifying the High Frequency (HF) and Low Frequency (LF) portions of the sound signal and sending them down two pairs of cables to the speaker. Multipin Speakon connectors have been developed to do this.
2)The process of having of having low-frequency speakers and high-frequency speakers driven by separate amplifiers.

Electronics
1) On a tape machine, the housing for and the channel circuitry which processes the signal to be fed to the heads, provide bias, and playback.
2) The branch of science dealing with the behaviour of electrons/charges in vacuums, gases, semiconductors and special conductors.
