Check the listing for details. MONO 7-outlet Isolated Pedalboard Power Supply - Medium. Condition: New. Listed at 189.99 USD. A Power Supply with Next-gen Features, Here at Last! With so many electronics to power, musicians are finding fewer wall outlets available in their homes, at venues, and elsewhere. Instead of hitting a wall, Sweetwater recommends hitting “Add to Cart” on a sophisticated MONO Power Supply. This unit’s revolutionary compact size smoothly integrates with home studios, laptop rigs, and traditional pedalboards. Measuring just under one inch in height, Mono Power Supplies eliminate the bulk of yesterday’s power bricks, which makes mounting fast and painless with practically any board. However, these devices compromise nothing for the sake of portability. Power is isolated, clean, and filtered at multiple points for total reduction or elimination of noise.
