Very few plasma screen televisions come with built in speakers. Some, however, are constructed with built in amplifiers on the sides that work with attachable speakers. These amplifiers are usually small (7 or 8 watts) but they do produce respectable sound. Owners of plasma screen televisions without built in amplifiers, or those who wish to have greater sound quality, still have many attractive options. The easiest is to connect the television to the receiver of a home theater system. This allows for the highest audio quality output possible. we at Shad Electronic all we do is to meet customer's demand in Customer Home Electronic.we distribute world wide with our head office in united state.where we manufacture various kind.
