Masters,newbie pa lang..Meron ako amp using tda2822m unfortunately nagkaroon problem yung isang speaker may output yung isa wala. later both nawalan ng output. ask lang kung paano ang tamang approach troubleshooting this problem. ayaw ko naman trial and error by buying a new ic tapos pick and place lang..thanks po...
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 feedin a separate housingmounted within or near the signal source, such as a turntable, microphone or musical instrument.
