Very week sound


Definitely need more info - such as type of amplifier or receiver, how many speakers you are running, whether the subwoofer is powered or not.
As a simple test procedure: Disconnect all speakers and plug in a pair of headphones. Get a strong audio signal? Good, move on. No signal or week signal, you have an amplifier issue before the audio even gets to the speakers.
Next: Disconnect all speakers, turn the volume down, and connect one speaker to the left output channel. Slowly increase the volume. If that works, do the same on the right channel. Everything OK? You're putting out enough gain on both channels. Sometimes one channel goes bad. You can still listen to your sound in mono moder, or drive two speakers from the single working output. Not stereo, but dual mono. Move on.
Connect left and right speakers but not the subwoofer. Repeat the test. Whatever is left is probably the problem. If the subwoofer is powered, check the power supply or incoming voltage. If the other speakers are driven off the subwoofer or powered from there, that's likely the problem.

Conncet a sony sub to a denon reciver


Depending on the model, there are two ways to connect a subwoofer to an amplifier, receiver or processor. The best way is to connect the subwoofer to the SUB OUT or LFE output of a receiver, but some subwoofers can be connected to the speaker level outputs of the receiver or amplifier.


1. How to Connect a Subwoofer to the Subwoofer Output


The preferred method of connecting a subwoofer is through the LFE or Subwoofer output (SUB OUT) of a receiver. Almost all home theater receivers (or processors) and some stereo receivers have a subwoofer output. The LFE (Low Frequency Effects) is a special output for subwoofers and is often labeled 'SUBWOOFER' not LFE. 5.1 channel programs on DVD discs have a dedicated .1 channel output with bass-only content that is best reproduced by a subwoofer. Connect the output of the LFE or Subwoofer jack to the Line In jacks of the subwoofer using a single RCA cable (the two jacks on the left in the photo). A 'Y-Cable' may be necessary to connect the LFE output to both the left and right channels of the subwoofer.

2. How to Connect a Subwoofer to Speaker Level Outputs
Some receivers and amplifiers do not have an LFE or Subwoofer output. In this case you can use the speaker outputs of the receiver to connect the subwoofer. Using speaker wire, connect the left and right channel speaker outputs of the receiver to the left and right channel speaker level inputs on the subwoofer (the speaker inputs on the right side of the photo). Using speaker wire, connect the left and right channel speaker outputs on the back of the subwoofer to the left and right channel front speakers.

Hope it helped..

With everything connected correctly there could be a couple of possible problems:

1. If your receiver has on screen display capabilities, you may need to turn the subwoofer output "on"
2. If your subwoofer has speaker wire inputs/outputs, you could run speaker wire to it, then to your speakers & test if the subwoofer is working... hence verifying that the receiver has a function to turn the subwoofer output on/off
3. The cable between the subwoofer & receiver could be bad. Try another cable.

Good luck!

The left and right outputs from the receiver go to the left and right inputs on the subwoofer and then you wire the left and right speakers to the left and right outputs on the subwoofer....it is sort of what we calll daisy chained

Hello ! I'm not sure how to connect my kef psw 2500 sub to my yamaha amp. I've got a subwoofer out on my amp but there's 4 inputs on the sub and I don't no which one to use ! Please help as getting...


Just for clarity, I need to explain what the four inputs are on the KEF subwoofer. There is a left and right RCA input which is the input signal to the subwoofer and there is a left and right RCA output which is the High Pass output from the subwoofer.

On the back of the Yamaha receiver, you said you have a subwoofer output. This output is most likely the mono subwoofer part of the home theater system and can be used if you like. The left right signal input into the KEF is summed into mono so if you only connect one channel you will basically reduce the signal level by 1/2 (-3dB) but it will work fine.

Alternatively, if your Yamaha receiver has monitor out and monitor in, you can run the monitor output signals to the subwoofer and you can then run the high pass outputs from the subwoofer back to the monitor in. This will give you the subwoofer and provide a smoother signal matching with your audio system.

It is not always easy to connect the subwoofer up to an integrated receiver/home cinema system using the high pass channels of the subwoofer as you don't always have access to the analog output and input of the front channels. In this case, just use the Subwoofer output or just the monitor out only.

I hope this solution is helpful.

When I hook up the speakers in the back to the left and right side for the in and out, do I connect the front or rear speakers. do the speakers connect to the subwoofer first then to my receiver or the...


I was trying to find an owner's manual or picture of the rear panel of the sub, but had no luck. The subwoofer is a powered type - or "active" speaker. This means it has a built in amplifier. These active subs usually provide for one or both "low level" and "high level" inputs. Low level signals are usually carried by shielded coaxial cables and have RCA type plugs on the end. The low level is also called "line level". This is an un-amplified signal that might be heard on cheap earphones - but that's about it. It is similar to the output of a tape deck, DVD or phonograph. These signals require an amplifier to be heard. If you have a sub woofer output on your receiver or amplifier, you could run a patch cable between the low level input on the subwoofer and the subwoofer output of the amp or receiver. You receiver or amp may call this output "low frequency effects" or similar. The front and rear speakers would then connect directly to the receiver or amp's corresponding connections.

If you lack low level outputs on the amp or subwoofer, you'll need to run speaker wires from the amplifier or receiver's front left and right speaker output terminals to the subwoofer's high level input terminals. High level signals are speaker connections or amplified signals. These are typically connections that accept bare wire connections. The front speakers would then connect to the subwoofer's front left and right speaker output terminals. The rear speakers connect to the amplifier.

I hope this helps - and good luck!

PDR-10 subwoofer has no output. 120vac to unit is


I have exactly the same situation with my PDR-10. Paradigm techs were of no help, don't me to take it to a service centre which i did. Of course when it was there they plugged it in and it stayed on for a day and a half so no problem right? Get it home, nothing, plugged and replugged, got it on once but not for long. Opened up back, everything including fuse looks solid and fine....to naked eye anyhow.

Hello,

First, make sure that the RCA's from the HU to your amp are properly connected, and fully seated on both ends. There are 2 sets of outputs. You should be using the ones on the left as you face the rear of the HU. Here is a link to the manual. Page 40 shows the connections on the back:

http://inform3.kenwoodusa.com/manuals/KDCX590.pdf

After making sure that everything is connected OK, check to see if you have the subwoofer output turned on your MP632U.

To do this, push the control knob on the right toward AM (toward the bottom). Subwoofer output switches off/on each time you push it. When it is on, the display reads "SW ON".

If this does not solve the problem, you most likely have a defect in either the HU or the amp.

Hope this helps! If it does, please rate as "FixYa." Thanks!

Installation Help


This means that you have purchased a three piece home theatre system. Two tweeters and a sub-woofer. Assuming you are using a Stereo player (Tape/CD/DVC)you have to connect the Left Output of the Stereo placer to the Left Input at the back of the Sub-Woofer and the Right output to the Right input of the subwoofer by cables. Then take tweeters and connect them to Right speaker and Left speaker output at the back of the sub-woofer ( note if the speakers are marked L/R, then connect them to the subwoofer output accordingly. In case you are using a 5.1 player, then only connect the front right and front left to the Right and Left input at the back of the subwoofer. You are and you can now start playing your music or movies and and you will get theatre quality sound.
