SOURCE: Sub Woofer Not Working

Make sure it is plugged in and the volume is up. Also make sure you don't have your sound muted. Do any sounds come out of your computer? Go to the control panel and click sounds and do a test.

SOURCE: After I transported Labtec APX

Open the unit and look forr the fuse to the unit. If power comes to the sub woofer drive board , check for the rail voltage to the IC.
Check the resistance of the subwoofer, make sure it i working.
If supply is coming to board, check for any signs of crack on the PCB. If not check for any loose connection on the IC.
If posible use a good soldering iron to solder suspected points in the board and the IC pins.
Since your set was working we must use the logic to look for a fault that occured during the transit.
if all the tests prove corrrect, then we can suspect the IC.
Make sure that there is input audio signals to the IC before you can confirm.

I have a active sub woofer (akari bazooka) but the only connections available are the speaker connections. The front of the sub woofer has volume adjustment. How can I connect this sub woofer to my Harman...

hi,
You can't connect the pre out of your AVR to this sub woofer. Do one thing connect the frond left/ right channel speaker "B" out of harman kardon to the sub woofers left right speaker in put. you can connect the speaker out "A" to your normal left right speakers. Remember to switch Speaker "A" and "B" in ON position in your AVR. Also do one thing go to the speaker setup of AVR and switch OFF (slelect NONE) the sub woofer.This will disconnect the sub woofer pre our and the sub frequency will mix with frond left right channels.

How to hookup

hi,
if u want to hook up the sub with ur av receiver the connect the sub woofer output of ur AVR to any one (left or right) input of ur sub woofer. then connect its power . set the frequency range between 90 and 120Hz. set the volume of sub woofer to 40% of its total. also check the av receives speaker setting. goto speaker setup and make ON the sub woofer out.

if want to connect the sub to a stereo amp without sub out. then connect the amps speaker line to the speaker input of sub woofer and connect the speaker out of sub to left and right speaker ( make sure to connect the red to red and black to black). set the volume and frequency as above

How it can be connected to a stereo amp

hi,
if ur amplifier have a pre out, then u can connect that to ur L/R input of ur sub woofer.

if not the only way is, connect ur amplifiers speaker output to sub woofers speaker input and then connect ur speaker to sub woofer speaker output terminal. remember don't inter change positive and negative wires.

if ur amplifier have speaker A,B connection then it is very easy. connect the speaker A to ur left and right speaker. then connect speaker B to ur sub woofer's left and right speaker input. be sure to make that speaker A and B switch is in on position. the power on both and check it. ( use good quality speaker cable to connect the sub woofer)

your sub woofer is designed to work , both at low level and high level input.

I have a JBL TLX CSS-SUB1 sub at the back are where you connect the speaker wires to the receiver but i don't know witch wire goes in what? i have no clue

The connection on the receiver would be the sub woofer out. Not a sub woofer out LFE, a sub woofer out with speaker wire connection. From there you plug it in to the top section of the available terminals on the sub you are referring to (speaker level input). One in positive and the other in negative matching what you did on the receiver with correct ends. The speaker connections underneath the top connections is for additional speakers like surrounds to be able to be connected directly to the sub woofer speaker level out for sound. This of course would be for an older receiver connection. I do not think it is possible to convert this connection to an LFE and have it work properly. If the receiver does not have sub woofer speaker connection and only a RCA out then you can try to connect both rear speaker connections from the receiver to the speaker level inputs on the sub and then connect your rear speakers to the speaker level output on the sub to power them. This is an active sub woofer but for some reason they made it connect as if it was passive. I am not sure if this sub is designed for really low frequencies required for movie or if it is better for music.

How do I hook up a non powered sub woofer on my htr-5630?

You will need an amplifier or 2 channel receiver. Hook the sub out rca jack to the rca inputs on this new amp or receiver and hook the speaker terminals on sub to speaker terminals on same amp or receiver. Your Yamaha receiver doesn't have any power for a passive sub.Just pick up any old fairly high powered receiver for fifty dollars and you're good to go.I use old dolby pro logic receivers as they are a dime a dozen today. Good luck.

Hi I own a Technics Hi-Fi system (Model SC-EH780) and would like to attach a subwoofer to it. I cannot find the subwoofer unit that is supposed to go with this system. Can you help?

Any powered sub-woofer will work with it. Check the back of the Technics, make sure there is an RCA output labeled "Sub-woofer" or "Woofer" or "Sub". If so, you can get any brand of powered sub woofer and it will work. A powered sub-woofer is one with an amplifier for the sub built into the box and you will need to plug it into an A/C outlet as well. The only exceptions to what will work with this unit is to make sure you are not buying a sub-woofer that is made to only work with the companion unit it is originally sold with. Many Panasonic and JVC sub woofers are like this. Just look for a sub-woofer that is not part of any system. Velodyne makes some really great sub-woofers that would work nice with yours, but they can be a little expensive, but they are very good.

If your Technics has no RCA output for the sub-woofer, you will need to make sure that whatever powered sub-woofer you buy has a speaker level input for it. Most powered sub-woofers have this feature, so that you may just run the front speaker outputs of the receiver into the subwoofer and then the sub-woofer will have a set of speaker outputs right below the speaker inputs so you can still have your front speakers connected to that and not loose anything from your system.

I hope I have explained this in a manner you will understand easy, if not just post whatever questions you may have right on this thread and I will get back to you as soon as possible.

It would also be appreciated if you could rate this solution if you no longer need any help from me. If you do require more help, please wait to rate this until we are finished. That way I do not get an undeserved bad rating when we have not even finished our communications.
By the way, A "Thanks for trying" and "Helpful" rating are really not good, they always end up lowering my overall score.
