View Full Version : SR 4722 1/4" speaker jack?

04-09-2016, 12:21 PM
Hello forum members, I have a problem locating the 1/4" HF BI-Amp jack for the SR 4722. Perf board (PCB) mounted jack, 8 pin. Speaker was purchased with jack completely gone. Other solutions to accomplish same function welcomed. Trying to restore to original condition. This cab also needs the 2206, an EV was installed in its place :crying:. Any help would be appreciated. BTW, model # of jack seems useless for any search. thanks for any help!

Did you try looking up the spec sheet to get a part number and calling jblpro?

I will give it a try, specs. say part not sold separately, require complete network replacement. Can't hurt to call. Thanks

The switching 1/4 inch jacks in that series of SR cabinets caused problems after they got a little age on them.
A lot of people replaced them with speakon connectors and wired in a switch to select between full range and bi-amp operation.

If you only ever going to use the cabinet in either full range or bi-amp you can hard wire it to the speakon and forgo a switch all together.

Hey Mike thanks for the support and thoughts were along the line you have proposed. I just wanted to minimize the installation to one jack and not do a rebuild. I will research schematic for installation of speak-on and switch configuration. I am hoping someone still has that elusive Sr 1/4" jack. thanks again
