Calista C2-88 Projector Electricity

Electrical current (the amount of electron charge passing a point in a conductor per unit of time) or voltage (the force pushing electrons to obtain electrical current).

Hertz
The unit of frequency. Equivalent to cycles per second. Abbreviation: Hz.

Calista C1-9 Home Theater 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)

ADAT
A trademark of Alesis Corporation designating its modular digital multitrack recording system released in early 1993.

Calista C3-S Security System Cascade
To set and interconnect two mixers so that the stereo mixing buss(es) of the first mixer feeds the stereo buss(es) of a second mixer.

Crossover Frequency
1) The frequency that is the outer limit of one of the bands of a crossover.
2) In the Lexicon 480L delay/reverberation effects unit, the frequency at which the bass frequency reverb time is in effect rather than the mid frequency reverb time.

Fader
A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel. Calista Reviews

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.

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 ...
