Calista C2-88 Projector Haas Effect

Simply stated, a factor in human hearing where delay has a much bigger effect on human perception of direction than level does.

Electret Mic
A condenser microphone where the capacitor plates are given a charge during manufacture which they retain, therefore requiring no external power supply.

Calista C1-9 Home Theater Digital Recording
1) ADAM : (Akai Digital Audio Multitrack). 12 track recording onto Video 8 tape. 16 bit, 44.1 or 48 kHz sampling rate.
2) DAT (Digital Audio Tape) Cassette-like system which has much higher quality than standard audio cassettes. Widely used in gathering sound effects, for news gathering, and for playback of music.
3) DCC (Digital Compact Cassette) Rival to DAT which also plays standard audio cassettes.
4) MiniDisc : Uses computer disk technology, rather than tape. A laser heats an area of magnetic disk which is then written to by a magnetic head. When cooled, the magnetic information is read from the disk by laser. Tracks can be named, and are instant start. Very theatre-friendly system.
5) Direct to Disk : Uses the hard disk present in most PCs as the recording medium.

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.

Calista C3-S Security System Cycles Per Second
A unit used in the measure of frequency, equivalent to Hertz. Cycles Per Second is an outdated term replaced by Hertz in 1948.

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.

Error Message
A prompt on a computer screen telling the operator that an error has occurred. Calista Reviews

Charge
The electrical energy of electrons. The energy is in the form of a force that is considered negative and repels other like forces (other electrons) and attracts opposite (positive) forces.

Calista C1-9 Home Theater Information Bits

The bits in the digital signal that make up actual values or commands being communicated as opposed to bits that are used for checking & correcting data or other purposes. Generation A term used to describe the number of times that the recorded audio signal has been copied. Calista C3-S Security System Frets Vertical metal wires which sit vertically on the guitar neck. High Hat A double cymbal on a stand which can be played with a foot pedal or by the top cymbal being hit with a stick. Calista C2-88 Projector 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). Bandwidth 1) The range of frequencies over which a tape recorder, amplifier or other audio device is useful. 2) The range of frequencies affected by an equalization setting. Impedance 1) A term for the electrical resistance found in a/c circuits. Affects the ability of a cable to transmit ...

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 ...
