The Boss PSA-240 power supply unit converts 230 volts AC mains power to 9 volts DC current, making it suitable for use with a wide range of Boss products. By providing a consistent - and above all, safe - power supply to your equipment, you can rest assured that all you need to do is plug in and play – which is a must for live musicians. The PSA-240 powers your equipment with minimal noise or interference, perfect if you’re in the studio or doing some home recording. As with all Boss products, the unit, cable and plugs are built to an exceptionally high standard of quality, whilst the slender 3-metre cable tucks away neatly.

Perfect Pedal-Board Powerhouse

The PSA-240 has been designed with a high milliamp rating of 200mA, making it the ideal power supply solution for equipment that has analogue and/or digital circuitry. The benefit to those who wish to use it to power their stomp boxes or FX pedals, is that thanks to the high milliamp rating, the PSA-240 doesn't introduce unwanted interference into your signal chain, giving you the power you need to feed the most hungry of pedals, without the noise. The compact unit can be used in conjunction with the Boss TU-Series tuner pedals and Boss daisy chain lead, to power up to 5 pedals at once, allowing you to slot it into any pedal-board setup with ease. Best of all, you can save yourself the hassle of spending money on replacement 9V batteries.

Whether you live for the stage, or spend most of your time in the studio, every musician needs a power supply that is quiet enough for you to forget it’s there, and is guaranteed to do its job without fail.
