    Hi all.

    I've recently bought a bassbalsereit studio II pickup (with 10-db in-line attenuator) and will be installing it on my double bass.

    There is a small preamp in the pickup which needs phantom power. I do not have a way of getting this at the moment. Was hoping there would be an XLR to Jack adaptor with phantom power - anyone know of such a thing? If not, what could I use?

    Next, it will be going into my Sadowsky preamp/DI pedal. From this, into my euphonic audio iamp800.

    This means I have 2 preamps in my chain, hopefully not a problem? The sadowsky is there more for the DI in this instance.

    Am I likely to come across any problems? The bassbalserelit needs fully balanced input jacks - will this setup work? I don't want to damage my gear or someones p.a.

    I'm not fully up to scratch with how all of this works so any advice would be gratefully recieved.
    Thanks

    What does Bassbals suggest for phantom? How much phantom is required? Jonas at www.Doublebassguide.com may know a phantom unit that will work.

    There are pres with phantom including Headway, Schertler Stat Pre. There are also dedicated phantom units. Don't know if they will work with the Bassbals. I would try the pickup without the Sadow Pre first. You may not need it. Doesn't the iamp have a di?

    Apparently the bassbal takes 7 to 48v of phantom power.

    The iamp does have a DI out, the amp needs looked at though. Bit of a hiss off it at the moment. I've found the sadowsky pedal dead handy tbh.

    I see bassbal has a pre/phantom unit for that pickup.

    Expensive though, certainly outside my budget.

    Just thinking, is a regular cheap DI box the answer? Means i have 2(!) in my chain but a poss cheap solution?

    A DI box may USE phantom power (if it is an active one and not battery powered), but does not deliver phantom power (at least the ones I know of).

    So this is not a solution for your problem. You need a box that delivers phantom power.

    Just curious, why did you choose that pickup? There are many fine, less expensive options.

    I got it 2nd hand for a v.good price. All the reviews I've seen for it as well were raving about it - from the older passive model to the newer one that I bought.

    Jdombrow - thanks, I'll check that out but its the SMPX-1X right?

    Yes, I probably wrote the number wrong.

    Unfortunately, it only has XLR out, I need a jack output.

    By "jack" do you mean 1/4" jack? You can get an XLR to 1/4" adapter or cable. I use one with my Schertler Pre All.

    Yes, an XLR to 1/4" but if I could get one of these with phantom power then I wouldn't need another box in my chain.

    A couple options I use:

    1) Denecke PS-1A 48V power supply. I clip it onto the quiver. I actually use it to power a DPA4099.

    Or...

    2) Acoustic Image Ten2, or any amp that has built in phantom power.

    There are other options. The Headway EDB-1 or 2 preamps have Phantom Power.

    Lohse recommends the Sampson S unit will work and it's $50.00. Has 1/4" and XLR out so it seems you could use it as a DI, too.

    Need a Wall-Wart for that.

    The PS-1A runs a on a single 9V battery.

    what about a small mixer (say 2 channel) with phantom power?

    Headway EDB-2

    Phantom power is 18V max, but it powers my DPA4099 just fine.
