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 ...
