Brooks Audio Design

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. Generating Element The portion of the microphone that actually converts the movement of the diaphragm into electrical current or voltage changes. Brooks Hi Fi speakers Graphic Equalizer An device with several slides controlling the gain of audio signal present which is within one of several evenly spaced frequency bands (spaced according to octaves). Layering The recording (or playing) of a musical part with of several similar sound patches playing simultaneous. Brooks RM 909 Highs Short for the term High Frequencies (the audio frequencies from 6000 Hz and above). Direct box Used in line to convert a high impedance signal into

A line around which a device operates. Example: In a microphone, this would be an imaginary line coming out from the front of the microphone in the direction of motion of the diaphragm. Floor 1) An alternate tam meaning Range (a limit on the amount the signal is reduced when the input signal is low by an expander or gate). 2) A shortening of the term Noise Floor (the level of the noise). Brooks HI FI projectors Clean Describes a distortion free sound with few effects. Line Input An input designed to take a line level signal. Brooks RM 909 Analog Recording A recording of the continuous changes of an audio waveform. Analog (Analogue) Representative, continuous changes that relate to another quantity that has a continuous change. Earth The British version of the term Ground (In electronics, a place that has zero volts). Joystick 1) A quad pan pot which distributes what percentage of on signal is sent to each of 4 outputs. 2) A control that i

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. Envelope 1) How a sound or audio signal varies in intensity over a time span. 2) How a control voltage varies in level over time controlling a parameter of something other than gain or audio level. Brooks RM 909 Earth The British version of the term Ground (In electronics, a place that has zero volts). Critical Distance The point a distance away from the sound source where the direct sound and the reverberant sound are equal in volume. Brooks Hi Fi reviews Echo Send The output of a console used to send a signal to an echo chamber or delay effects device. Baffles Sound absorbing panels used to prevent sound waves from entering or leaving a certain space Controller 1) In MIDI, a device that generates a MIDI signal to con

The area from 3 feet away from the sound source up to the critical distance. High Impedance Impedance of 5000 or more ohms. Brooks RM 909 reviews Cardioid Pattern A microphone pick up pattern, which has maximum pick up from the front, less pick up from the sides, and least pick up from the back of the diaphragm. Audio Most often referring to electrical signals resulting from the sound pressure wave being converted into electrical energy. Brooks HI FI projectors 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. Echo Send Control A control to send the signal from the input module to the echo chamber or effects device via the echo buss. Amp 1) An abbreviation of the term Amplifier (A device which increases the level

1) A punch in of the all of the tracks being recorded in a recording session. 2) On Solid State Logic consoles, placing an outboard piece of gear in the channel by patching and activating a switch. Ambient Micing Placing a microphone in the reverberant field (where the reverberation is louder than the direct sound) so as to do a separate recording of the ambience or to allow the recording engineer to change the mix of direct to reverberant sound in recording. Brooks Hi Fi reviews Compact Disc CD A small optical disk with digital audio recorded on it. Feedback Control The control on a delay line or delay effects device that controls the amount of feedback. Brooks RM 909 reviews Layering The recording (or playing) of a musical part with of several similar sound patches playing simultaneous. Gain Control A device that changes the gain of an amplifier or circuit, often a knob that can be turned or a slide that can be moved up arid down. Bi-Amplificatio
