I. The Ethos is shipped with a Power Adapter that has the following characteristics:
a.) INPUT VOLTAGE: 120VAC @ 60Hz
b.) OUTPUT VOLTAGE: 12 VDC (Unregulated) @ 500mA
[The unregulated 12 VDC actually = 16VDC with the ETHOS load]
II. The Ethos will also operate with Power Adapters that generate a (5%) REGULATED +18VDC output.
III. DC Dunlop Brick using the +18VDC output. This adapter works with many input power voltages
around the world.
IV. Voodoo Lab, Pedal Power 2 and 2+. Use the L6 outputs (channels 5 OR 6) which provide between
+16 and +17VDC. Note: You must set the channel dip switch to the NON-normal position.
Tu peux donc acheter un transfo de 18VDC régulé, par ex dunlop en a, de mémoire ECB04.

Can I Use a +9V AC to DC Adapter?
An un-regulated +12V AC to DC adapter rated at 500mA is required based on the following: The ETHOS provides filtering circuitry that removes the noise (60 Hz Ripple) from typical AC to DC unregulated power adapters. This filtering circuitry develops a voltage drop across it, so the adapter voltage becomes +9VDC by the time it reaches the ETHOS analog circuits. Additionally, an unregulated +12VDC supply (not a regulated supply) is required due to the fact that it actually outputs 15 to 16 volts with the ETHOS load. This higher voltage provides the adequate headroom for the ETHOS to operate correctly. Using a +9VDC AC to DC external adapter will result in poor ETHOS performance.
