Question lang po: Ok lang po ba na walang "Pre-amp" ang isang Amplifier?
: Ano naman pokaya ang effect nito?
Newbie lang po Maraming salamat po sa inyo' ^_^
n general, the function of a preamplifier is to amplify a low-level signal to line-level. A list of common low-level signal sources would include a pickup, microphone, turntable or other transducer. Equalization and tone control may also be applied.
In a home audio system, the term 'preamplifier' may sometimes be used to describe equipment which merely switches between different line level sources and applies a volume control, so that no actual amplification may be involved. In an audio system, the second amplifier is typically a power amplifier (power amp). The preamplifier provides voltage gain (e.g. from 10 millivolts to 1 volt) but no significant current gain. The power amplifier provides the higher current necessary to drive loudspeakers.
Preamplifiers may be:
incorporated into the housing or chassis of the amplifier they feed
in a separate housing
mounted within or near the signal source, such as a turntable, microphone or musical instrument.
