Audio Alchemy DST cable power supply
 

I posted this question on rec.audio.tech, but given the low signal-to-noise ratio there I"m sure I have a better chance for an answer here. :)

I misplaced the power supply for my Audio Alchemy data stream transceiver (DST) powered digital cable. I have the "owner's manual" that came with it, but it doesn't discuss the power requirements.

Can anyone describe for me the connector (1/8" mini phone plug?) polarity and voltage?

Thanks in advance...
