preamplifier [prē′am·plə‚fī·ər] (electronics) An amplifier whose primary function is boosting the output of a low-level audio-frequency, radio-frequency, or microwave source to an intermediate level so that the signal may be further processed without appreciable degradation of the signal-to-noise ratio of the system. Also known as preliminary amplifier. Preamplifier A voltage amplifier suitable for operation with a low-level input signal. It is intended to be connected to another amplifier with a higher input level. Preamplifiers are necessary when an audio amplifier is to be used with low-output transducers such as magnetic phonograph pickups. A preamplifier may incorporate frequency-correcting networks to compensate for the frequency characteristics of a given input transducer and to make the frequency response of the preamplifier-amplifier combination uniform.

| Audio recording was done with Duo Professional Preamp. In order to determine the time of the signal with the respect to the scintillator, a linear fit was used to determine slopes in the preamp signal and in the discriminator output of the scintillator. Audio recording was done with Duo Professional Preamp. |
