Members thunderpaw Posted April 11, 2004 Members Share Posted April 11, 2004 I need to connect unbalanced 1/4 inch TS on my patch panel to an xlr so I can connect a pair of Mackie 1530s for a gig next week. Never got around to making TS to xlr cables. I have a pair of Rat Shack 1/4 to xlr impedance matching transformers. Would this give me the line level to xlr connection that I want, or is line level a different animal than "high impedance"? Otherwise, guess it's the strap negative and shield on the xlrs and go that way. (It's Easter Sunday and I am short on xlr connectors). Thanks!Kim Link to comment Share on other sites More sharing options...
Members agedhorse Posted April 11, 2004 Members Share Posted April 11, 2004 Kim, Ditch the transformers, they are mic level, and have a (aprox) 6:1 voltage step-down to the XLR side to achieve the impedance translation. Either wire a 1:1 line level transformer with the primary connected to the tip & sleeve and the secondary side connected to pins 2 & 3, with an optional jumper (usually switched) between the sleeve/shield of the 1/4" and pin 1 of the XLR. Otherwise, make up an adapter cable with tip going to pin 2, sleeve going to pin 1 and 3. Lifting the pin 1 connection may improve hum issues in some instances.

Members thunderpaw Posted April 11, 2004 Author Members Share Posted April 11, 2004 Thanks, Andy! I'll restock my xlrs and start soldering. Kim Link to comment Share on other sites More sharing options...
Members agedhorse Posted April 11, 2004 Members Share Posted April 11, 2004 Time to order "stocking stuffers" from Mark eh? Link to comment Share on other sites More sharing options...
Members thunderpaw Posted April 11, 2004 Author Members Share Posted April 11, 2004 Got my list and I'm checking it twice Kim PS: I appreciate the insight you provided into the CAD KM412 kick mic. I had thought about getting one of their basic kits with mounts just to have on hand in a pinch. Can't get the drummer to pop for anything (although he's a multi-brand "endorsee" and something may come down the pike...eventually) and I can't afford the Shure/Sennheiser/AKG route at this time. 'Twas good news...thanks! Link to comment Share on other sites More sharing options...
Members agedhorse Posted April 12, 2004 Members Share Posted April 12, 2004 For the most part, CAD is one of the best kept secrets. Try the D-189 vocal mic and it's sure to catch your attention. Like a cross between a B-58 and a B-87... another real sleeper. Link to comment Share on other sites More sharing options...
Members thunderpaw Posted April 12, 2004 Author Members Share Posted April 12, 2004 Isn't CAD somehow related to the old Astatic company? I'll be on the lookout for a D 189 to try...thanks. Link to comment Share on other sites More sharing options...
Members agedhorse Posted April 13, 2004 Members Share Posted April 13, 2004 Astatic was a division of CAD, now they are all owned by Omnitronics. Link to comment Share on other sites More sharing options...
