POLARITY "PHASE FLIPPER" INTERCONNECT KIT
 

Part of my critical test/setup procedure involves placing one of the the mains speakers out of polarity with the subwoofer, and critically matching the subwoofer signal until it cancels with the mains. That procedure is here: www.soundoctor.com/testcd

Another procedure involves feeding white noise into both the L and R speakers out of polarity with each other. (That procedure has nothing to do with the sub(s), which may be off or disconnected for the procedure. That procedure is here: www.soundoctor.com/testcd/whitenoise.htm

If you have "normal" speaker wires feeding your mains the procedure is easy - you simply reverse the red and black wires to one of the speakers.

However if you have powered speakers which are fed with balanced XLR type 3-pin connectors, the procedure is more difficult and often quite annoying. This kit makes it easy. (If your powered speakers are connected with unbalanced RCA connectors, there is no easy way to do this test.)

You simply use the straight F-M cable as an "extension", for example to lengthen the cable TO the speaker, so you can now stand in front of the speaker and plug and unplug the polarity flipper cable. The polarity flipper cable itself is plugged into the self-powered speaker.

Now you are able to stand 8 feet or so in front of your speakers and follow the procedure easily. The "KIT" looks like this:

Now you are able to stand out in front of the speakers, and plug the male connector back and forth into the two phase flipper connectors to do the tests.
 
PRICING
The price for the kit is $90 plus shipping. The wires are 12' long. If you DON'T already have my TEST CD the kit including the CD is $100. If you are interested email or call. A PayPal button is coming.
