n.
An electronic circuit or device that detects and strengthens weak signals, as from a radio receiver, for subsequent, more powerful amplification stages.

preamplifier

(priːˈæmplɪˌfaɪə)
n
(Electronics) an electronic amplifier used to improve the signal-to-noise ratio of an electronic device. It boosts a low-level signal to an intermediate level before it is transmitted to the main amplifier. Sometimes shortened to: preamp

pre•am•pli•fi•er

(priˈæm pləˌfaɪ ər)

n.
a device in an amplifier circuit, as of a radio or phonograph, that increases the strength of a weak signal for detection and further amplification.
