Sex and the balanced interconnect.


Caught your eye, didn't it.

I am contemplating a new line level crossover, and it comes with XLR balanced outputs. My power amps have XLR balanced inputs, so I thought...why not give balanced a try. The problem is that both the crossover and the amps have female connectors, so that the interconnect needs to be male on both ends (just like an rca interconnect). I find cables offered with a wide variety of connector configurations, but I can't find any XLR cables configured male-to-male, although I could put in a special order and have them made.

Is it unusual to require male-to-male configuration?

In the XLR connector the three pins are within a shroud that protects them from damage, so the male-to-male configuration is OK in that regard. By the way, I do live in Massachusetts, so same-sex interconnects are legal.
I have the power amps, CarverPro zr1600, and the manual and inspection of the hardware confirms that a male plug is necessary on the input cable. The connectors on the chassis accept XLR, TRS, or TS 1/4 phone plugs, all male. (TS are used for single ended operation). The circuit is truly a differential input for balanced interconnects, as one can check on the schematic available on the web site.

I do not physically have the crossover: an Ashley is what I am considering. However, I do have the manual which clearly states that the interconnect needs a male connector.

Industry standards don't seem to be universally followed. In reading the Ashley manual I learned that JBL drivers pull the cone IN for a positive input. OUT is standard for other brands. I discovered this for myself when I wired up my subwoofer systems. (Actually I thought I had mixed up the connections at the drivers and didn't unscrew them from the enclosure to check).
Thanks to everyone who remarked on the unusual male-to-male XLR cable configuration. Very careful rereading of the Ashly manual suggests that the XLR chassis output is a male. All the diagrams about pin assignments show only male XLR connectors. The female reference occurs once burried in text about other things.

I wonder why this is the standard. RCA and phone plug interconnects are all male-to-male.

I am considering this crossover, to replace very satisfactory Marchand units, because I want to be able to easily change the SW/Main crossover frequency. My Marchand crossover consists of three of their boards which I put together into a chassis, which is located in the cellar, with my power amps. Changing frequency involves taking off the cover and pluging in a different frequency select module. I have determined that there is no best crossover frequency for my system, which includes custom built multi driver subwoofers that are capable of good response to higher frequency than most subwoofers. Organ music, loud orchestral pieces, and mass chorus performances are best when the six big dynamic drivers pump it out: X/O 80 - 150 Hz. Chamber music is best when the Maggies do most if not all: X/O 50 Hz.

Because the new X/O will be located with the source equipment, (not in the cellar with the amps) the interconncts to the power amps will get a lot longer, and that's why I am interested in trying the balanced line capability.

Thanks again. I'm glad I asked.
Jafox...It has been pointed out that with a locking connector if someone trips over the wire (and don't say it never happens) the electronics end up on the floor. Nothing is perfect.
