DCM SUBWOOFER PROBLEM.

1
Hook up your equalizer to your receiver if it does not have preamp-out channels. The equalizer should always be between the receiver and the amplifier. Your amplifier will need integrated preamp-out and preamp-in connections to work with this method.
2
Purchase 2 pairs of RCA cables. To run a signal from your stereo receiver to the equalizer and back again, you'll need 2 sets of RCA cable (the same kind that is usually used to connect source components like turntables and CD players).

• The length of the RCA cables should match the length of the distance between the receiver and the equalizer.

3
Connect one pair of RCA cables between the receiver and equalizer. Connect one pair of cables to the tape monitor output channels on the receiver and the other end of the cable to the left and right channel inputs on the equalizer.

• You will usually find these channels on the rear of the equalizer.

4
Connect the other pair of RCA cables between the receiver and equalizer. Connect the other pair of cables from the output channels on the back of the equalizer to the tape monitor input channels on the back of the receiver.

• Right channel jacks will usually take the red colored RCA plug while left channel should take white or black RCA plugs.

5
Use your equalizer. Turn on the receiver and switch the front panel output control to the "Tape Monitor" setting. This opens the tape monitor channels and means that the sound will travel through your equalizer before being sent to the amplifier. Adjust the equalizer knobs according to your preferences.

• You should now be able to manipulate the controls on the equalizer to change the frequency response or tone of your music.
• To switch on the "Tape Monitor" setting you should depress the button on the front panel of the equalizer.
• If you have a tape deck connected to the tape monitor channels then you will have to remove this before connecting your equalizer.

I had a brief look at the spec and it says the speaker outputs are banana sockets/plugs.
Once the four speakers are connected, or two with the fader control adjusted, it should produce good sound and if it does the next stage will be to connect the subwoofer with RCA plugs into the dedicated outputs.

I suggest you reread the manual.

Connecting an Equalizer to a Receiver Before beginning, purchase RCA cables. In order to run the signal from a stereo receiver to the graphic equalizer and then on to the amplifier, two sets of RCA cables are needed. These are basic cables used to connect auxiliary components like record players and CD players. The length of the RCA cables should be about the same length as the distance between the receiver and equalizer.

1. Connect Graphic the Equalizer to the Receiver

The first step in this setup is to connect the graphic equalizer (EQ) to the receiver. Most receivers will have preamp-in and preamp-out connections. Some have tape monitor connections. It's preferable to connect the EQ to the preamp-in or preamp-out because the tape monitor won't allow for connection to the amplifier as well.

2. Connect the RCA Cables

The first set of RCA cables should connect the receiver and equalizer. Connect one pair to the preamp output channels and the other end to the left and right input channels on the EQ. These are on the back side of the equalizer. Usually, the colors will correspond to the RCA plugs. That means connect the red plug to the red jack and the white plug to the white jack. Then connect the second pair of RCA cables between the receiver and the amp. Match the colors in the same way.

3. Connect the Amp to the Receiver

Now the amp can be connected to the receiver via RCA cables in the amp inputs on the receiver. This will create a loop from the receiver through the EQ and amp and back to the receiver so that all three units are connected.

4. Test Graphic Equalizer

Turn on the receiver, amp and equalizer. Once they are powered up, try controlling the sound with the equalizer knobs. They should fine tune the music according to your preferences. It's easy to change the frequency response or tone of the music with the equalizer knobs.

The Jensen JS650 does not accept line level input so you need to use the Front B speaker output from your Sony receiver and not the RCA subwoofer output. Even though your subwoofer is active, it does not support line level (RCA) signals.

Just connect the subwoofer as you would a pair of speakers. Once connected, you make sure the front panel speaker switch on the Sony is set to A+B so you get sound from your existing speakers (A) and subwoofer (B).

I hope that works for you.

First do not panic by seeing all sockets in the back side of the receiver.You can connect 5 speakers and one subwoofer on the speaker A switch and maybe a second pair of stereo speakers on the B switch.All the speaker sockets have red and black terminals, so do all speakers. Just get decent cables ( You can buy a whole connection Kit if you want ) and connect the corresponding outlets to you speakers.If you have a powered subwoofer connect the subwoofer input to a socket labeled Subwoofer pre out on the RXV. You will need a RCA to RCA cable for that Next you will need a coaxial or Optic fiber cable to connect a DVD player digitally. The back of the DVD player will have a socket marked coaxial out, and so does the RXV's backside. Just link them .
Turn on the system everything should work. If you are not getting DVD sound there is small button on the RXV front panel called Digital input -- set it to auto ( keep pressing the button and it will scroll through various modes). Also remember to switch on speaker A on the front panel.

You shouldn't connect the subwoofer to the TV. Just connect the Right and Left audio cables (red and white RCA plugs) to the TV audio out and then the other side goes receiver's audio in. If you are using the subwoofer that came with the unit, connect it to the sub port (purple and grey or black striped). The red and black striped cable goes to the subwoofer control.

If you are using another active subwoofer, connect it to the RCA jack labeled Subwoofer Audio OUT.

If you have a 3-plug RCA cable that is a composite video cable. The yellow plug carries the video, the red and white carry the audio signal. This cable is most often used for connecting older VCRs and game systems to a TV (or newer devices to an older TV). Thus leave the yellow jack dangling if using it for an audio cable.

Set your TV to use the external audio speakers and the receiver will take care of the signal to the subwoofer. (You only would connect the speakers individually for a computer sound system.)

I hope this helps.

Your subwoofer probably has both high-power inputs and "normal"low inputs. The first are for receivers, which don't have link-level output for sub, so they are able to take already amplified signal as input.
You need to use link-level input of your sub and connect it to subwoofer-output of your receiver. The output is marked as OUTPUT - Subwoofer and is black-color RCA plug (don't confuse with subwoofer INPUT under MULTI CH INPUT).
Receiver has only mono output for subwoofer. If your sub has stereo input (white/red RCA plugs), connect just the left channel to the receiver, it will still work.
Don't connect anything to the speaker output on the sub, you don't need that.

I guess you don't have the owner's manual for this?
You can get it here:
MS907 Subwoofer manual
The manual contains connection info.

Connect the receiver's Subwoofer Line Out to the Sub's Line In with a single RCA cable.

Not knowing your specific receiver I can only advise that you get into its setup and 1) tell it you have a subwoofer; 2) set the other speaker types you have regarding Large vs Small (meaning can they handle REAL bass); 3) go through all the channel level setup; 4) Rock On.

you coudl use a single rca to a left and right rca cable. However most woofers will have a lfe single rca input on the woofer that you connect to a single rca on the receiver.

Are you sure you are not confusing the +/- on the woofer that is used to connect your speakers? ie. my woofer has the +/- so i can connect to my front speakers and my receiver to filter the low frequency sounds via the woofer.

hope this helps
