yeah you just need a passive preamp. you can visit www.marchandelec.com and get either kit or assembled one in any configuration you want to order: i.e. number of inputs/outputs, stereo, mono, or dual-mono etc...
If you've some bucks to spend extra than Placette is claimed to be the best passive one.
