Calista C1-9 Home Theater Frequency

The number of cycles of a waveform occurring in a second.

Ground Adapter Plug
Adapts a three pronged electrical plug to a two pronged wall outlet. This bypasses the ground and may create a hum in the system. A lack of a good ground can cause mild electrical shock when touching a microphone.

Calista C3-S Security System Bi
A prefix meaning two.

Ambient Field
A term with the same meaning as the term Reverberant Field (the area away from the sound source where the reverberation is louder than the direct sound).

Calista C2-88 Projector Crosstalk
Leakage of an audio signal into a channel that iris not intended to be in, from an adjacent or nearby channel.

Hearing Limitation
An inability of the ear to hear important characteristics of sound under certain conditions. Characteristics that can be affected include pitch, level, clarity, presence and direction.

Decibel (dB)
1) Relative measurement for the volume (loudness) of sound. Also used to measure the difference between two voltages, or two currents. See Zero dB.
2) A numerical expression of the relative loudness of a sound. The difference in decibels between two
sounds is ten times the common logarithm of the ratio of their power levels. Bose

Cut
1) One selection (one song) on a pre4ecorded music format.
2) A term with the same meaning as Mute (to turn off a channel or a signal).
3) To reduce gain of a particular band of frequencies (with an equalizer).
4) To not pass a particular band of frequencies (said of a filter)

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 ...
