Device for converting the electrical signal from an amplifier back into sound waves, most commonly by vibrating a paper cone Most speaker systems are composed of a number of sources - each designed to handle a specific range of frequencies See Tweeters and Woofers, Bi-Amplification MATRIX OUTPUT : Set of outputs on a mixing desk which allows the user to preset a number of output configurations e g on a 8 x 8 matrix, each of the 8 group outputs from the channels can be routed to any or all of the matrix outputs
A loudspeaker is a piece of equipment, for example part of a radio or hi-fi system, through which sound comes out. = speaker. or speaker In sound reproduction, device for converting electrical energy into acoustical (sound) signal energy that is radiated into a room or open air (see acoustics). The part of the speaker that converts electrical into mechanical energy is frequently called the motor, or voice coil. The motor vibrates a diaphragm that vibrates the air in immediate contact with it, producing a sound wave corresponding to the pattern of the original speech, music, or other acoustic signal
