Calista C3-S Security System Earth

The British version of the term Ground (In electronics, a place that has zero volts).

Error Concealment
Putting replacement information bits into a digital audio signal to replace lost bits when the digital recording or processing system cannot verify whether the lost bits were l's or 0's but can make a good guess by comparing the known bits that were close in position to the lost bits.

Calista C2-88 Projector Fat
Having more than a normal amount of signal strength at low frequencies or having more sound than normal (by use of compression or delay).

Impedance
1) A term for the electrical resistance found in a/c circuits. Affects the ability of a cable to transmit low level (e.g. sound) signals over a long distance. Measured in Ohms. Speakers are rated according to power handling capabilities (Watts, W) and impedance (Ohms).
2) The total opposition offered by an electric circuit to the flow of an alternating current of a single frequency. It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker's impedance changes with frequency, it is not a constant value.
3) The opposition to alternating current.

Calista C1-9 Home Theater Instrument Out Direct
Feeding the output of an electric instrument (like an electric guitar) to the recording console or tape recorder without using a microphone.

Feed
To send an audio or control signal to.

Headstock
The area of the guitar at the end of the neck where the strings are tuned. Bose

Auxiliary Equipment
Effects devices separate from but working with the recording console.

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 ...
