Many manufacturers of musical instruments do not equip their products with power adapters. Some devices run on batteries, of course, but that is unlikely to be very cost effective if you use them intensively. It's also possible that your power adapter stops working or the adapter that powers your recorder, wireless microphone receiver, charger or effects pedal may get lost, for instance. In this category, you'll find universal power adapters that are suitable for different devices and brands. For many devices it's essential that you choose the right type of power adapter. We therefore recommend that you purchase an adapter that matches the requirements of your device.
