Brooks HI FI projectors Circuit

1) One complete path of electric current.
2) Similar to definition 1, but including all paths and components to accomplish one function in a device.

Driver
See transducer. Dynamic Range �" The range between the quietest and the loudest sounds a device can handle (often quoted in dB).

Brooks RM 909 reviews Gain Structure
The way in which the gain varies in the stages or sections of an audio system.

House Sync
A synchronization signal such as SMPTE time code that is used by all recorders in the control room.

Brooks Hi Fi speakers Images
The squaring of the waveform that happens in the conversion of digital audio bits into analog signals.

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.

LED
A light that allows current to flow in one direction only and emits light whenever a voltage of a certain level or beyond is applied to it.

Electret Condenser
A condenser microphone that has a permanently polarized (charged) variable capacitor as its sound pressure level sensor.

1) The level difference (in dB) between normal operating level and clipping level in an amplifier or audio device.
2) A similar level difference between normal tape operating level and the level where the distortion would be 3%.
3) The difference, in decibels, between the peak and RMS levels in program material.

Chip
1) A slang term with the same meaning as the term IC (a miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment).
2) The thread cut away from the master lacquer to make the groove, while disc recording.

Brooks HI FI projectors Frequency
Practically speaking, high frequency means high pitch and low frequency means low pitch.

Cut
1) One selection (one song) on a pre4ecorded music format.
2) A term with the same meaning as Mute (to turn off a channel or a signal).
3) To reduce gain of a particular band of frequencies (with an equalizer).
4) To not pass a particular band of frequencies (said of a filter)

Brooks Hi Fi reviews Cut-Off Frequency (Turnover Frequency)
1) The highest or lowest frequency in the pass band of a filter.
2) The highest or lowest frequency passed by an audio device (the cut-off frequency is usually considered to be the first frequency to be 3 dB lower than a reference frequency in the middle of the bandwidth of the device)

Amplifier
A device which increases the amplitude (level) of an electrical signal (making it louder).

Line Out (Output, Send)
Where a signal leaves the board or component.

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