Amplifiers

Although amps are built quite simply and do with only a few controllers and switches, there are major differences between every apparatus. A detailled comparison shows an objective view of each of their services.

An amplifier consits of the following components: mains adapter, signal input, power level, protective circuits, indications and, as the case may be, a remote control or monitor. The mains adapter and transistors with their cooling element have the most weight and size. Therefore the mains adapter must have the right dimension, so it can provide enough power for the speakers plus the power loss of the transistors.

Output rating as it is today develops a power loss of several hundred watt which have to be dissipated. A cooling convection wouldn´t be enough. Therefore, as a rule, pressure cooling by ventilation is inserted to increase the dissipation of the cooling element by far.

In order to reduce the total weight of the amplifier - especially if it has to be transported from one location to another - continuative amp- and adapter-designs have been developed in the past few years. At present these new models are situated in the higher price category. Yet, it´s only a matter of time untill amps with switching power supply become affordable.
