Power supplies for power Amplifiers​

A Power Amplifier is an essential component when it comes to driving any loudspeaker system. However, different speaker systems have varying requirements, and thus, the amplifier needs to be powerful enough to cater to these specifications. A Heavy Duty Power Supply is highly recommended since it not only enhances the amplifier’s performance but also ensures that it can handle even the most difficult and demanding loudspeaker systems with ease. Moreover, a high damping factor is achieved by combining the amplifier’s driver stage with a low impedance power supply, leading to high-quality output signals that are pleasing to the ear.

 

In recognition of this, Audio Products offers a range of power supply options, each with a specific application in mind, so that whatever your power requirements are, there is an ideal option available for you.
