I have the same problem with the sub woofer not putting out any sound. I have 7 speakers and everything works except the subwoofer. I tried the setting in speaker configuration ~ set the sub to LFE+Main. No changes. I've been told that I need to turn on the Digital connection? If that is the solution, I can't find the correct setting for Digital connection.

SOURCE: AVR 810 Denon Receiver Sub Woofer Hookup?

Denon AVR-810 was a quite out-dated model. I had owned since 1992. It shown 'Protection' on the screen for 2 months ago and not yet been fixed. Better to replace a modern one or repair it at a reasonable costs.

Sound only coming from 3 of 6 speakers

A 5.1 sound card will give output in all channels only if the audio being played is also 5.1.

Normally out of 6 Speakers only 2 front and sub woofer will play sound, in case of a DVD or Movie which has 5.1 encoding, all 5 will come alive.

Also, Dolby Prologic II and Dolby Digital will convert a 2 channel input into psudo 5.1 enviornment but Dolby has to be in hardware or speakers or Receiver.

MX6050D Subwoofer Issues

Hello, welcome to Fixya!

Fault is either from the main system or the sub-woofer itself.

You need to test both unit in order to detect which of the two is giving the fault, so that you can concentrate on the faulty unit.

Test the woofer with a AA battery or any other battery. Put your ears close to the woofer and observe if you will hear any sound. If the woofer makes sound, then it means the woofer is working, but if it doesn't make sound, then it means the woofer is defective. Or you can disconnect one of the working speakers and connect the woofer to that part. If there is no sound, then obviously, the woofer is defective.

If the woofer seem to be working, then the unit needs to be tested also.

Connect one of the working speakers to the sub-woofer's section of the main unit. If the speaker doesn't bring out sound, check the system's menu settings, check the volume and make sure the sub-woofer volume is raised to the highest level and not on mute. ( Note that most Theater systems has separate volumes for each speakers). If the volume is raised to the highest level and there is still not sound from the woofer part, then it means the woofer channel has burnt. It could be a fuse or a defective channel. At this point, I think you need help from a repairman.

I hope the above is clear.

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...

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.

I am wondering about car amplifiers, I don't know what kind to get, I have Alpine 6.5" 2-Way Car Speakers (SPS-600), 80 watt as my front speakers, and Alpine 6 1/2" 2-Way Car Speakers (SPR-17C), 100 watt...

I would strongly recommend that you get a 5 channel amp that puts out 75watts rms per channel that will deliver between 200-300 watts to the sub channel. I use planet audio amps myself and they run strong all day every day-maybe you could look at a planet audio vrx 600.5(5-channel) it throws 100w x4 and 200 or 300 to the subs depending on the resistance of the sub. Good luck

We have a very small living room now. I would like to set up just the center speaker and the two rear speakers and disconnect the two front speakers and the subwoofer. Is that possible?

well it depends on what audio device installed on your computer coz other you can make an adjustment for 4 channel, 5 channel & 7 channel speakers including sub woofer and surrounds. try to check your setting or the best way is to unplug your front speaker and sub woofer. good luck!!!

Yamaha Dsp-A1000 5 ch amp Bought a used amp will be hooked to an awia reciever and speakers also have two subwoofers need help to install correctly witch connections to use

if you wanted to use your receiver as your controller and source then try to find out the receivber has got a bridge (jumper) between the pre-amp stage and the power amp stage. if your receiver does not have that, then you can just connect your receiver tape record out to one of your DSP inputs. subwoofers, the DSP has got a sub woofer out connector. you can use that (RCA type) to your sub woofers. put in series because DSP has got only one output for sub. or, you can connect your subs directly to the mains speakers, parallel connections. maybe one sub to your left and the other to your right channel.
