Power Amps & Attenuators

Power amps and attenuators used to be relatively simple devices. A guitar amp attenuator has made it possible to crank amps at low volumes and power amps were the link between preamps and speakers. Nowadays, with the rapid development of digital technology, guitar power amps and attenuators can have a plethora of applications at home, in the studio and on stage.

The job of a power amp is to drive a speaker. In all guitar amps, there is both a preamp to create the sound and a power amp to create the volume. Stand alone power amps are useful for guitarists who use their pedal board to create their sound and want to run it directly into a speaker rather than a traditional guitar amp.

Attenuators allow you to enjoy the full power of your amplifier - both at its preamp and power amp stages - but intercept the signal before the speaker, so that you have more control of the overall volume. They do this by showing the speaker the correct ‘load’ or resistance. ‘Reactive load’ boxes have different resistances at particular frequencies, accurately replicating a real speaker.

Attenuators often now have the ability to take a ‘line out’ for silent recording. Many even have built-in ‘Impulse Responses’ or ‘IRs’. IRs are digital simulations of both speakers and rooms which enables you to have a natural amp sound without going through a real speaker. This is ideal for quiet home recording and for consistent live sound.

Why Should I Choose a Power Amp or Attenuator?

• Have greater control of your sound at home and on stagey
• They can be simple devices or all-in-one tools for amp recording
• Often equipped with Impulse Responses and line outs
