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

No signal from closed circuit system


If you monitor will accept a composite connection (RCA) than I would try that first but the right way to do this is to change the connectors on the cable. Wire length is in play here as well as wire type. Before I ask for more detailed information give the adaptor a try.

Dome camra wire connection with bnc


Preparation
Before installing your RCA camera scout the area and confirm that you will be able to run the cable from your surveillance digital video recorder (SDVR) to your camera. You may want to use RG59 Siamese cable, which is a single cable system with three wires: a coaxial cable for the video and a positive and negative wire to provide power to the camera. If you are installing your camera outside, place it at least 10 feet high to minimize tampering, or put your camera in a dome or other protective housing.
Coax Cable

BNC connector
If you use Siamese cable to wire your RCA camera, you will run the cable first, and then install a BNC (bayonet Neill-Concelman--named for the inventors) connector on each end of the cable. BNC connectors vary by manufacture; install the BNC connectors according to the connector instructions. To get a general overview of the process, see the Resources section for a video on installing BNC connectors.
Power Wires
Plug with standard lamp-type cord

Plug with standard lamp-type cord
Your camera came with a power supply with an integrated power wire; the power supply plugs into a standard wall outlet and the other end plugs into your camera. The cord is probably not long enough, in which case you will have to cut it and splice the Siamese in the middle to deliver power to your camera. The power supply wire is designed like a standard lamp cord and must be cut in half and split. One of the wires will be marked with a stripe, a series of dashes, a rib on the insulator or some other marking (just like a lamp cord). The marking indicates that this is the positive wire. After cutting the supply cord, connect the portion with the camera plug on it to the Siamese cable at your camera and then connect the power supply portion to the other end of the Siamese cable near your SDVR. The positive (marked) power supply wire should be connected to the red Siamese wire and the other wire connected to the black Siamese wire. While many people use wire nuts to connect the wires, connecting the wires with a wire beanie (see Resources) will provide a higher quality installation.
Plug-and-Play
Plug-and-play cables make it easier for homeowners to install their cameras. These cables incorporate all three wires into one cable system and come with connectors preinstalled so that you will not have to install connectors or cut wires. This is slightly more costly than assembling your own cable, but it will save you time and you will not have to purchase special tools to install the connectors. Run your plug-and-play cable and connect it by following the instructions which come with your cable. See the Resources section for a video on installing plug-and-play cables.

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.

My wire got pulled off my sub how can i fix it


Hello gatmanfromda,

I'm assuming you mean the "tinsel" lead going from the connector to the sub cone. In many cases, the wire can be soldered back on. It takes care and patience and you need to be sparing with the solder and prevent it from stiffening the tinsel lead. Otherwise it will tear out again when the sub cones moves out. If the cone itself was damaged when the lead pulled off, you can use silicone sealant to repair it. Again, be sparing with the silicone and allow it 24 hours to set up before trying to operate the sub. If the wire pulled off from the connector terminal, just solder it back on.

Hope this helps.

Which jacks to wire the subwoofer to?


Your receiver should have an RCA connector on the back panel that will be marked "sub woofer" or "LFE out". That connects to your sub woofer with a standard RCA type cable. Also, some powered subs have left and right speaker level inputs and outputs in which you would indeed run the sub woofer through the speaker outputs. The down side of that type of connection is that the line level converter inside the sub woofer will take a slight amount of your receiver's output power, although that is rarely detectable. Also, if you have a Dolby Digital receiver, using this connection method will take away systems ability to accurately control the low frequency effects of a soundtrack.

Good Luck,
BB

that subwoofer has dual 4ohm voice coils, if your amp can handle 2 ohms, you would put a wire from the positive (+) on the amp to the positive on both connectors on the sub, then hook the negative (-) on the amp to the negative on both the sub connectors that will be a 2 ohm load on your amp make sure your amp at 2 ohms is not more than 600 watts RMS or 1200 max.
