Calista C2-88 Projector Frequency

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

Effects
1) Various ways an audio signal can be modified by adding something to the signal to change the sound.
2) Short for the term Sound Effects (sounds other than dialogue, narration or music like door closings, wind, etc. added to film or video shots).

Calista C1-9 Home Theater Hard Disk (Hard Disc)
A storage unit for digital data that has rigid disks coated with magnetic material in a housing that includes the drive mechanism.

Foot (Foot Drum)
Another name for Bass Drum (the largest drum in the Drum Kit which puts out bass frequencies and is played with a foot pedal).

Calista C3-S Security System Generating Element
The portion of the microphone that actually converts the movement of the diaphragm into electrical current or voltage changes.

Amplitude
The strength of a vibrating wave; in sound, the loudness of the sound.

Electromagnetic Field
Magnetic energy put out because of current travelling through a conductor. Bose

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 ...

Calista C1-9 Home Theater Amplifier

A device which increases the amplitude (level) of an electrical signal (making it louder). In Port A jack on a MIDI device or computer that will accept an incoming data signal. Calista C3-S Security System Blending 1) A condition where two signals mix together to form one sound or to give the sound of one sound source or one performance. 2) Mixing the left and right signal together slightly which makes the instruments sound closer to the center of the performance stage. 3) A method of panning during mixing where instruments are not panned extremely left or right. Lead Sheet A written chart showing the melody, lyrics and chords of a tune with full musical notation. Calista C2-88 Projector Electronics 1) On a tape machine, the housing for and the channel circuitry which processes the signal to be fed to the heads, provide bias, and playback. 2) The branch of science dealing with the behaviour of electrons/charges in vacuums, gases, semiconductors and special...
