Ambient Field A term with the same meaning as the term Reverberant Field (the area away from the sound source where the reverberation is louder than the direct sound). DC Abbreviation for direct current. Calista Reviews Circuit 1) One complete path of electric current. 2) Similar to definition 1, but including all paths and components...

1) Effect used to create echo…echo…echo…echo…echo… 2) In more advanced systems used in very large venues, delay can be used to time the arrival of the signal to the speakers in the back of the room so that people in the back hear the sound coming from those speakers at the same time that the sound coming from the speakers in the front of the room arrives. Key The control of a dynamics processing device by an external audio signal. Calista C2-88 Projector ADSR The letters A, D, S &R are the first letters of: Attack, Decay, Sustain and Release.

Pressing and immediately releasing the switch on a computer's mouse. Foot Pedal 1) An effects device where the amount of the effect can be controlled by a musician with his foot. 2) The beater mechanism of a foot drum that is activated by the drummer's foot to play the drum. 3) Any device, like a volume control, that can be operated by the foot. Calista C1-9 Home Theater Error Message A prompt on a computer screen telling the operator that an error has occurred. Coincident Microphones (Coincident Pair) Two microphones whose heads are placed as lose as possible to each other so that the path length from any sound source to either microphone is for all practical purposes, the same. Calista C3-S Security System Axis 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. In Short For "in the circuit," in oth...

1) In multitrack tape machines, this term means the same thing as the term Track (one audio recording made on a portion of the width of a multitrack tape). 2) A single path that an audio signal travels or can travel through a device from an input to an output. Electrostatic Charge The excess or deficiency of electrons in a given area. Calista C3-S Security System High Frequencies The audio frequencies from 6000 Hz and above. Auxiliary Equipment Effects devices separate from but working with the recording console. Calista C2-88 Projector Earth The British version of the term Ground (In electronics, a place that has zero volts). Hypercardioid Pattern A microphone pick up sensitivity pattern where the least sensitive pick up point is more than 90 degrees but less than 150 degrees off axis (usually 120 degrees). Echo Chamber 1) A room designed with very hard, non-parallel surfaces and equipped with a speaker and microphone. 2) Any artificial or ele...

An index signal (digital data that gives the machine information of where selections start, their selection number, etc.) on a DAT or CD. Ground Lift A switch that breaks the connection between the ground point in one circuit and the ground point in another circuit. Calista C1-9 Home Theater Edit A switch that does different things depending on the operational mode that the machine is in: 1) If a computer-controlled transport is in "Stop," pushing the "Edit" switch deactivates the computer-controlled tension system and allows the reels to be moved by hand to find the exact spot desired on the tape. 2) If the machine is in "Play", the "Edit" switch makes the take-up reel cease taking up the tape and it falls to the floor. 3) If the machine is in a fast-wind mode, the tape lifters are defeated so the tape is in contact with the reproduce head and the engineer can hear where the selections begin and end. Insulator A substan...

Short For "in the circuit," in other words "active." Condenser Mic (Capacitor Mic) A microphone that uses the varying capacitance between two plates with a voltage applied across them to convert sound to electrical pulses. Condenser microphones need a power supply to provide the voltage across the plates, which may be provided by a battery within the case of the microphone, or it may be provided from an external phantom power supply. A condenser mic is more sensitive and has a faster reaction to percussive sounds than a Dynamic mic and produces a more even response. See Electret Mic. Calista C1-9 Home Theater Ground Lift A switch that breaks the connection between the ground point in one circuit and the ground point in another circuit. Joystick 1) A quad pan pot which distributes what percentage of on signal is sent to each of 4 outputs. 2) A control that is separately controlling two functions at one time.
