PA Amplifiers come in several different designs to suit the specific power and input requirements of the situation.
The classic PA Amplifier to most people is a mixer amplifier system which combines several microphone inputs and auxiliary connections in one big box. This tradition lives on in the feature laden PD-8 from Power Dynamics which is a customer favourite here at Electromarket.
For large sound systems we have a selection of powerful rack mount amplifiers from brands such as Crown and Behringer, or for building installation purposes we have zone amplifiers from Monacor and Bosch.
