Power Supply Facts
Boomerang® E-155 Chorus*Delay and Boomerang® III Phrase Sampler
The E-Series pedals are very forgiving and will work with many types of power supplies. Any supply with the following output specifications will work: 9VAC, 9VDC negative tip, 9VDC positive tip, and an output capability of 600 to 1000mA. *
Boomerang® Phrase Sampler, Plus (V2) and Original (V1)
Our first two loopers require power supplies with these specs: 9-10VAC, 500-1000mA. That's an output of 9 to 10 volts Alternating Current with a 500 to 1000 milliamp capability.

NOTE - A standard stomp box 9VDC supply will NOT work with the Rang™ Plus or Original. However, the following power supplies will. The part numbers might vary if you are outside of the USA or Canada.

Burkey, Flatliner Pro
Voodoo Lab, Pedal Power AC
Line 6, PX-2 AC Power Supply
Digitech, PS0913B-120
All Boomerang® products use the following power connector: 2.5mm inside diameter, 5.5mm outside diameter.

Power Supply Basics
All power supplies that plug into the wall are called AC adapters because the wall power is AC (Alternating Current), but they can OUTPUT either AC or DC (Direct Current). There are NO polarity issues with a power supply that outputs AC; this only applies to power supplies that output DC.
Voltage rating of a power supply - The voltage is the critical number. Running a 9V device on an 18V power supply will make it run hot and cause damage. A 9V device won't run on a 6V power supply.
Amperage rating of a power supply - Stated in mA (milliamperes), this is the current rating and represents a maximum capability. Unlike the voltage, it is not a constant value. The power supply will deliver only what the device asks for. If a pedal wants 600mA and the supply can provide only 300mA, then it won't work though no damage will occur. On the other hand a pedal needing 400mA will work just fine with a 750mA supply.
* In order to provide for some flexibility in power sources for the E-Series pedals, the power jack is NOT connected directly to the audio signal ground but is routed through a full-wave bridge rectifier prior to a connection to all internal circuitry. This approach allows for the use of AC power sources and auto-sensing of DC power sources but mandates that the power source MUST BE FULLY ISOLATED from any direct or indirect path to the ground side of any audio/control inputs or outputs connected to the pedal. A direct path could be created by using a power supply that uses a 3-wire mains plug and has one side of the output connected to the mains ground (rare). An indirect connection can occur when a single power source is 'daisy chained' between several pedals and one or more of the additional pedals has its audio ground connected directly to one side of its power jack (common). In this case one wire in the power cable attached to the E-Series pedal is indirectly connected to the audio signal ground and this violates the full isolation requirement. This situation cannot only create a 'ground loop' hum problem but could also severely damage the power supply and/or the E-Series pedals. In general it is recommended that the E-Series pedals always be powered with the power adapter supplied with each unit. Boomerang Musical Products, Ltd. cannot be held responsible for any damages which result from the use of any power source other than the one supplied with each unit by BMP.
