Calista C3-S Security System Binary

A numbering system based on two. In binary there are two symbols used ("l" and "0").

Golden Section
A ratio of height to width to length of a room to achieve "good acoustics" and first recommended by the ancient Greeks. The ratio is approximately the width 1.6 times the height and the length 2.6 times the height

Calista C1-9 Home Theater Comb Filter
1) The frequency response achieved by mixing a direct signal with a delayed signal of equal strength especially at short delays.
2) Loosely used to also describe effects that can be achieved with comb filtering as part of the processing.

Link
(Said of compressors and dynamic processing units.) To combine the control input signals of two channels of a compressor (o

Calista C2-88 Projector 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.

Controller
1) In MIDI, a device that generates a MIDI signal to control synthesizers, sound modules or sample playback units.
2) A remote control unit for a multitrack tape machine which controls transport functions as well as monitor selection switching functions and record ready/safe status of each track.
3) Any device generating a control voltage or signal fed to another device's control input.

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). Bose

Close Micing
A technique of placing a microphone close to the sound source (within one foot) in order to pick up mainly the direct sound and to avoid picking up leakage or ambience.

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 ...
