Calista C1-9 Home Theater Diaphragm

A thin flexible membrane or cone that vibrates in response to electrical signals to produce sound waves. Distortion is usually referred to in terms of total harmonic distortion (THD) which is the percentage of unwanted harmonics of the drive signal present with the wanted signal. Generally used to mean any unwanted change introduced by the device under question.

Compact Disc, Interactive CDI
A Compact Disc, usually containing audio, video, and text, which the user can interact with in that the display or playback changes after the user performs some action.

Calista C3-S Security System Auxiliary Equipment
Effects devices separate from but working with the recording console.

Critical Distance
The point a distance away from the sound source where the direct sound and the reverberant sound are equal in volume.

Calista C2-88 Projector Bass Roll Off
An electrical network built into some microphones to reduce the amount of output at bass frequencies when close-micing.

Bulk Dump
Short for System Exclusive Bulk Dump (a method of transmitting data, such as the internal parameters of a MIDI device to another MIDI device).

Central Processing Unit

Calista C1-9 Home Theater Bi

A prefix meaning two. Dynamic Mic Robust type of microphone which picks up the sound on a diaphragm connected to a coil of wire which moves within a magnet. An alternating current is induced into the wire which provides the electrical output. Most dynamic mics have low output impedance of 200 Ohms. See Condenser Mic. Calista C3-S Security System Instrument Amplifier A device that has a power amplifier and speaker in a case (or in separate cases) to reproduce the signal put out by an electric instrument (such as an electric guitar) and to allow the instrument to be heard. Flutter 1) High-frequency variations in pitch of a recorded waveform due to fast speed variations in a recorder or playback machine. 2) Originally, and more formally, any variations (fast or slow) in pitch of a recorded tone due to speed fluctuations in a recorder or playback unit. Calista C2-88 Projector Capacitance The property of being able to oppose a change in voltage or store an electr...

Calista C1-9 Home Theater Electric Current

A more formal term meaning the same as the term Current (the amount of electron charge passing a point in a conductor per unit of time). Buss (Bus) A wire carrying signals to some place, usually fed from several sources. Calista C2-88 Projector Amplifier Sound equipment that converts the low voltage, low current signal from a tape deck, mixer etc. into a higher current signal suitable for driving speakers. See Power Amplifier, Crossover. Compression Ratio How many dB the input signal has to rise above the threshold for every one dB more output of a compressor or limiter. Calista C3-S Security System Input Monitor A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. In this mode, the tape machine's meter will read the input signal. Line Out (Line Output) Any output that sends out a line level signal, such as the output of a ...

Calista C1-9 Home Theater Amplifier

A device which increases the amplitude (level) of an electrical signal (making it louder). In Port A jack on a MIDI device or computer that will accept an incoming data signal. Calista C3-S Security System Blending 1) A condition where two signals mix together to form one sound or to give the sound of one sound source or one performance. 2) Mixing the left and right signal together slightly which makes the instruments sound closer to the center of the performance stage. 3) A method of panning during mixing where instruments are not panned extremely left or right. Lead Sheet A written chart showing the melody, lyrics and chords of a tune with full musical notation. Calista C2-88 Projector 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...
