A425 subwoofer, more bass? wires came off, no bass managment.


I wouldn't cross wires or leave one disconnected. Can you solder the wires back on the the control knob? Did you feel the subwoofer cone to see if it's working at all? I would guess the wire you didn't connect, is the subwoofer wire. Try putting it back to original cofiguration and solder the wires in place.

My sony STR-DE475 has no bass. The bass just went out after running it for 6 hours.


Either the subwoofer speaker or its amplifier failed - they couldn't handle the extended use. Simple test to find out which: put the volume really low, connect another subwoofer (or a large normal speaker) to the bass output on the receiver and play some music. If you get sound then the original subwoofer is faulty, just get a new one. If you don't get sound then the amplifier for the subwoofer channel has failed. You could replace it yourself if you have enough electronics repair experience, otherwise it will be cheaper to just get another good sh low end receiver from a site like Ebay.

My Mirage S10 subwoofer light comes on showing the subwoofer is on but I cannot get any bass sound to come on. How can this be resolved?


More diagnosis first. We can't assume the source is squawking bass to this thing and you don't mention that you know that to be the case. IS it? The problem could be up the food chain.

We also don't know if you're feeding it Speaker Level or Line Level.

Prove the subwoofer amp is dead or alive by jacking in any source you have that has an RCA output (Tape Out on your unnamed source, CD, TV, etc). Turn the sub volume down to minimum to start as most RCA outputs are at maximum volume. Try that to assess the amp's health. Still dead? Get it worked on.

H?,
You have a very good system...one of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer.
.your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2)..in order to activate the sub woofer amplifier you need to make a selection on the surround modes while you are switching the modes of the surround you will see the speaker position on the display of receiver as well..if you do not see the sub woofer it wont be activated..Sound Field Program (A.F.D) is a good example to test it..
Take care and please Remember to rate/vote and give me 4 Thumbs Up
for Helping out the Community :)

Hope this helps!

--------------------
Additionally please follow the instruction on your user manual to activate the SUB ,as is follows..

-----------------
BASS-OUT
Low-frequency (bass) signals can be directed to the
subwoofer and/or the front left and right speakers
according to the characteristics of your system. This
setting also determines the routing of the LFE (low-
frequency effect) signals found in Dolby Digital or DTS
sources.
Choices: SWFR (subwoofer), FRONT, BOTH
• Select SWFR if you connect a subwoofer. LFE and
low-frequency signals from other channels are directed
to the subwoofer according to the speaker settings.
• Select FRONT if you do not use a subwoofer. LFE and
low-frequency signals from other channels are directed
to the front speakers according to the speaker settings
(even if you have previously set the front speakers to
SML).
• Select BOTH if you connect a subwoofer and you want
to output low-frequency signals from front channels to
both the front speakers and subwoofer. LFE and low-
frequency signals from other channels are also directed
to the subwoofer according to the speaker settings. Use
this function to reinforce low-frequency signals using
the subwoofer when playing back sources such as CDs.

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..

Set your equalizer to you a V shape or U shape pattern, bass effect can only attain by adding a powered subwoofer, (amplifier and subwoofer). subwoofer without an amplifier doesn't sound good, your system doesn't have enough power to drive your subwoofer.

Hi Cassie, unless your receiver is a surround reciever, it won't have an actual subwoofer output. The good news is that you can use either a "line out" jack or a "tape out" jack instead, which most receivers do have. These jacks always have the signal, so there are no special settings to remember - simply operate your receiver as usual. Everything comes out of these jacks, not just the bass - but it won't matter since your subwoofer will only reproduce the bass frequencies. The bass information is generally identical in both left and right channels, so either the right or left jack should work fine, and it's okay to leave the other one unconnected. The only bad thing is the line and tape outputs are not affected by the receiver's bass and treble controls, so you'll have to control the bass volume at the subwoofer if it has a control. If you can't control the amount of bass you hear, turn up the volume and reduce the treble which will give the illusion of more bass. I'm assuming you have "powered" subwoofer (has its own built-in amplifier). Good luck!
