Wire came ondone inside subwoofer with trying to look at BCN connector


I orginally had a problem with my BNC connector to the sub, which part of the connector was pulled out (FROM MY CHILD PUSHING ON THE WIRE) I opened up the sub to see how it was attached and somehow the red wire on the circuit board shown came off. I can not see where this came undone from. Boston Acustics customer service would not send me a skematic to see where it goes to. Would you be able to help me out. The sub still works if i connect it using the alternate speaker direct hook-up.The sub was bought in 2001. The info on the circuit board is indigo 630069 rev 2 Any help would be appreciated, If you need to ask me questions, my cell phone is 603 401 5710 thanks John

The red wire means a + positive connection of DC voltage supply,this wire is in power supply section.for sure use a lens for better look for the tracing mark or remains of a break solder .You begin your trace in power supply section capacitor + positive side .

Hope this may help;

Write mfg and model No to search for any documentation available or take it to an authorized service shop where they may have some wiring diagram.

John,
This will be difficult if not imposible to diagnose remotely. I notice that you are in New Hampshire based upon your phone area code. If you are in southern NH, take a trip to the Lancaster Flea Market where there is a servicer that may be able to help. Free onsite estimates! If the unit is a Boston Accoustics sub, there may not be schematics available to the public primarily because the amp sections of their subs are made by another company. Other than having the board examined, there is little we can do for you.

Sorry,
Dan

How do i set up my subwoofer sawm40


Sounds like you have a passive subwoofer, you run speaker wire from 'front speaker receiver out' to the subwoofer, the 'subwoofer out' to your front speakers. Seem like your sub has a crossover that grabs the bass frequencies and passes off the rest to the front speakers

If you have a 'subwoofer line out' on your reciever and a 'line in' on you subwoofer then just use that single wire, this would be for a powered sub. You know that you have a powered sub if your sub has a power cord attached to it.

Can I use a JS650 with a new Harman Kardon AVR1600 Home Theater receiver? The HR is 7.1 however the JS650 has only speaker wire connectors. Thank you.


Yes. You run the front channel speaker wiring to IT then the the front speakers attach beyond it from thye OUTS. Set the level for the sub to match the other speakers using the knob on the back.

Your amps don't 'drive' the sub, they just pass through it to the fronts while the sub samples the programming.

Popping harman kardon subwoofer


Mine did the same thing all of a sudden. The problem is a AC mains detection circuit that seems to affect many previous HK sub models. The solution that worked for me was to replace capacitor C112 on the main pcb of the subwoofer amplifier. You need to remove it from the circuit board with a soldering gun and replace it with a higher rated capacitor. I used a 2u2 40v and the subwoofer is working perfectly again! :)

How do I connect this subwoofer to my reciever


The simplest way is to insert the sub into the speaker wire run -- connect your receiver's speaker output to the sub input, then the sub output to the speakers.

These are the "High Level" connectors on the left side of your sub.

If your receiver has a subwoofer out (either one or a stereo pair) then you'll get better quality sound by connecting that output to the "Low Level" connector or connectors on the right. If you have stereo, then use both connectors. If your receiver only has one subwoofer output, then connect it to the left (may or may not me marked as "mono" depending on the age of your sub)

Hopefully that helps. If it's confusing, post back questions or post the details (brand and model) for your receiver.

No Sound from Jamo E6 Sub


More likely there is a bad solder connection or a bad connector contact inside the unit, could also be a blown or dried up electrolytic capacitor.

Check the line signal input plugs, if they are soldered directly to the board then check the solder around the pins - if it has circular cracks, you need to resolder the pins.

Also check any other components on the board for such cracks on the pins, including internal connectors, disconnect, clean the pins if necessary and reconnect them.

If any electrolytic capacitors have a bulged top, they are blown and need to be replaced.

It could as well be something else, but your description suggests either a fault at the input connectors or some trouble with the input signal level sensing circuitry (no signal to the sensing circuit may be caused by connectors, no response from the sensing circuit may be caused by bad capacitors or other faulty components in or around that section).

Hope you can find out what it is and fix it...

Dayton sub-100 connection


You have it upon one of several truly odd "standards" in the AV industry but the answer is simple if not quite logical. You will use an RCA type cable from the Sub out or LFE on the receiver to just one of the two inputs on the subwoofer. I usually use the one on the right but it really doesn't matter. The other connectors would be for a system with out a sub out where the speaker wire would be run first to the subwoofer and then out to the speakers. This will not be used at all in your case.

Best hook- up Polk psw10 sub woofer to yamaha rx-v663 receiver


You will not need to y connect your subwoofer, if you have only one RCA sub out on your receiver the other end of the RCA connector cable goes into the left input on most powered subs, there is no loss of signal, the option exist as some receiver do sport a double RCA sub out.
