Diago PS09 Isolator Adaptor

The Diago Isolator prevents noise generated by a digital pedal from making its way into your signal. You might come across a pedal that sounds perfect when powered on its own power supply, or with a battery, but is extremely noisy when powered alongside other pedals. This is a fairly common problem amongst modern digital pedals and sounds terrible, so we designed the Diago Isolator to solve this.

Many digital pedals have separate power and signal grounds in order to prevent noise from the digital micro-controller entering your signal path. In most analogue pedals, however, the power and signal grounds are shared. When a digital pedal and an analogue pedal are fed from the same power supply, noise generated by the digital pedal is transferred to the signal through the common ground in the analogue pedal.

This isn’t a particularly complex problem and is easily fixable by the manufacturers of digital pedals. In fact we don’t really know why they haven’t tackled it more urgently. Until they do though, a Diago Isolator will keep your signal clear from the noise of those pesky digital boxes.
