Customer concerns about powering the Op-2 Comp:
Question: what are you planning to offer or recommend as a power supply for the Op-2 Comp now that you've switched over to 12v?
Answer: We have tested a number of wall wart style 12VDC power supplies for low noise and selected the one we feel performs the best. We are now offering a TC Electronics branded supply for optional purchase with the Op-2 Comp.
Question: What if I don't want a wall wart? I want to power all my pedals from one power supply/brick. Not a wall wart and no daisy chains.
Answer: There are many products on the market that supply at least 400mA at 12v and also supplies 9v to multiple jacks. Some examples are the Voodoo Lab 4x4, Voodoo Lab ISO-5, Eventide Powerfactor 2, Cioks Big John, AC10, DC10, TC10, Ciokolate and the upcoming DC10 Link. Additionally, the TRex Goliath has 12vdc at 450 ma outputs. While a bit more obscure, Yankee Power has several power supply products that can supply 12 vdc at 400 ma minimum.
Question: But I already have the MXR Iso Brick. I need something that can power your 12v pedal(s) and the Iso Brick, which needs 18V DC @ 2A regulated.
Answer: I'm not aware of anything that does exactly that. In this situation, the only solution I can think of is a custom power supply that I could build for you. It would have 3 regulated DC outputs. Two 12v 400mA outs and one 18v 2A out, all isolated. Not an inexpensive solution though!
