An electronic device that amplifies sound signals to a point where they great enough to be heard through a speaker.
Electronic devices that are used to increase the volume of sound. In live performance amplifiers are used for guitars, vocals, keyboards, and any instrument that can be miked (linked to a microphone). The stuff that bands use is, in principle, identical to your average home Hi Fi, just a lot more powerful (and expensive). Found on http://www.bbc.co.uk/radio2/soldonsong/glossary/a.shtml

<microscopy> When the projected image of the microscope is projected less than 250 mm the objective may be moved enough from its usual position (for visual observation) to degrade the image. It can be restored by adding a lens above the ocular to bring the image into focus on the desired plane but with the objective still in its position of b...Found on http://www.encyclo.co.uk/local/20973
