Need help fast - Unbalanced Preamp to Balanced Amp

Ralph - Thanks so much for your detailed response. I have a good friend who can make a cable as you describe. He tried once before, but apparently had it grounded differently, thus the hum.

Almarg - The Placette is a temporary thing. I will eventually go with an active preamp. Thanks again for your advice.

Hi i have a set of cables like KR4 MENTIONED.I will send them to you ,just pay for shipping.

Energizer - Thanks for the offer. I need RCA at one end and female EBU at the other. Is this the config of your cables?

Ken, re Energizer's nice offer, keep in mind as I indicated earlier that commercially made xlr-to-rca cables (and adapters) in most cases have pin 3 shorted to pin 1 (ground). I would not use that cable on an xlr OUTPUT without first checking with Rowland.

See this thread for an example of a problem that was caused by doing exactly that, albeit with relatively inexpensive equipment.

Also, I don't know how similar your Rowland is to the Continuum model that is currently listed on their website, but for that model, at least, it describes the xlr output as being "high current." That most likely means it has low output impedance, which will mean that the device driving pin 3 will be forced to supply LOTS of current if it is shorted to ground.

Regards,

With regard to Al's comment immediately above, you could set up the cable so that only pin 2 of the XLR at the preamp end is used. That way the inverting out would not be grounded and possibly damaged.

FWIW in the case of our preamps they are completely tolerant of pin 3 being grounded to pin 1.
