amplifiers, plural;
  1. An electronic device for increasing the amplitude of electrical signals, used chiefly in sound reproduction

  2. A device of this kind combined with a loudspeaker, used to amplify electric guitars and other musical instruments

  1. electronic equipment that increases strength of signals passing through it
  2. Generally, an amplifier or simply amp, is any device that changes, usually increases, the amplitude of a signal. ...
  3. Amplifier is the debut album of the Manchester alternative rock band Amplifier.
  4. Amplifier are an alternative rock trio from Manchester, England fronted by singer and guitarist Sel Balamir. The band’s self-titled debut album was released in 2004 by Music for Nations. Their second album, Insider was released in Europe in 2006 on the SPV label.
  5. The Exponents are a New Zealand rock group. They formed in 1981 as the Dance Exponents, after vocalist Jordan Luck and guitarist Brian Jones disbanded their first group, Basement, and relocated from the South Canterbury town of Timaru to Christchurch. ...
  6. An appliance or circuit that increases the strength of a weak electrical signal without changing the other characteristics of the signal; An amp; a particular type of speaker used in live performances
  7. (Amplifiers) Eclipse DA7232 (x2) Sub
  8. (Amplifiers) Those can be approximately linear (i.e. 1/α ~ VC) or dB-linear.
  9. TV or Radio Signal amplifier/booster
  10. A device which increases signal level. Many types of amplifiers are used in audio systems. Amplifiers typically increase voltage, current or both.
  11. A component that increases the gain or level of an audio signal.
  12. A circuit that produces a larger output power, voltage or current than was applied at its input.
  13. An electronic device which boots or increases a small signal to a higher level, usually for transmission, scale convenience, or noise immunity.
  14. typically refers to a device which adds strength to a signal for a 'better' and / or longer performance ability. Amplifiers can be found for both wired and wireless equipment. ...
  15. An electronic device that amplifies sound signals to a point where they great enough to be heard through a speaker.
  16. A device capable of increasing the magnitude or power level of a voltage or current that is varying with time (frequency), without distorting the waveform of the signal. The incoming signal is far too weak to power a speaker system. ...
  17. A device which draws power from a source other than the input signal and which produces as an output an enlarged reproduction of the essential features of its input.
  18. electronics that convert low level inputs to high level outputs.
  19. A device, inserted within a transmission path, that boosts the strength of an electronic or optical signal. Amplifiers may be placed just after the transmitter (power booster), at a distance between the transmitter and the receiver (in-line amplifier), or just before the receiver (preamplifier).
  20. Device used to boost the strength of an electronic signal.
  21. An electronic device which generates a high power signal based on the information supplied by a lower powered signal. A perfect amplifier would add or subtract nothing from the original except additional power - these have not been invented yet
  22. An electrical circuit designed to increase the current, voltage, or power of an applied signal.
  23. A device which increases the level of a signal.
  24. Expression device which increases the pump suction level by decreasing the amount of atmospheric pressure normally bled into the system. Used in Ampico, Coinola, and certain other instruments.
  25. 1. An electronic device that in concert or studio work takes the output of the sound board and increases it enough to drive the loudspeakers. 2. ...
