All Ethos Amps must only be powered using the power adapter furnished with the unit. Use of other power adapters can result in poor performance or damage the Ethos Amp.
The Ethos OD Preamp 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.
