Daisy Chain Pedals Noise

Noise when using daisy chain i bought a new pedal eqd dirt transmitter my first real pedal and linked it to my multi effects pedal with a d addario patch cable and using a daisy chain from my boss power supply to power both of them.

Daisy chain pedals noise. Let s define the terms. Multiple pedals are hard enough to manage from both a cabling and settings perspective the last thing you want is the power supply affecting your sound signal as well. The problem with a daisy chained power supply is that all of the connections share a common ground which can introduce unwanted noise or hiss into your signal. A daisy chain allows you to connect and power multiple guitar pedals from one power supply.

Take note of what kind of undesirable noise you are experiencing from your rig. Powering with a daisy chain or multi output power supply that shares its current across the outputs will result in a high pitched noise at the output like you describe. Using a daisy chain psu doesn t mean there will be noise but it opens up more avenues for noise issues to occur. Each plug in the chain is connected internally to all the others going from one plug to the next so current and ground are shared between each plug.

You must always use an isolated power supply or multi output supply with isolated outputs like our zuma or ojai power supplies to avoid any additional noise in your audio. In our case an effects pedal daisy chain is a wiring scheme where multiple pedals are wired together in sequence from a single source of power. Whether any one user hears noise with any pedal chain depends mainly on whether a ground loop has leaked noise into the audio path. A daisy chain is a supply with one main power module and a string of plugs.

If you suspect it is then try removing the power source from the mix and run all your pedals on battery power so they are isolated from ground.
