Home Theater sub not Thumping

An often overlooked issue with quiet or no sub woofer output is that if the front and/or mid are set as Lrg or Med there is no SubWoofer signal or it is drastically decreased. So check your speaker size settings (Generally found in the setup of the receiver and you may be pleasantly surprised by the return of the missing thump. Your neighbors? Not so much ;)

Trying to hook up a KLH sub woofer, S100ETH, PSW8-100 to a VCR reciever. Reciever has sub woofer connection but does not works on the KLH sub woofer. What is the problem ?


I suggest you go over your receiver set-up instructions. See if you need to set the receiver to acknolwedge the addition of the subwoofer. It should be in your receiver set-up steps. Just as a check, hook up one of your other speakers to the subwoofer lead to see if gets audio signal. I'm guessing the issue is your receiver settings.

htddw7600, brand new, sub amp is not working, only way to get any bass sound is to unplug the sub cable from back of main amp and touch it on side of sub out port.


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..

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.

I have a sony HTDDW7600, i cannot get the dedicated subwoofer amp to work. The fan is running on it, but for some reason the only way i can get it to do anything is to unplug the cable that goes from the main amp to the sub amp and touch it on the outside edge of sub out port on the main amp doing that makes the front light up and the subs do random bass. but plugged in normally i get nothing on the front and no bass. It is brand new btw.

Connection of a subwoofer to Yamaha ZX-V490


Get a powered sub-woofer that has speaker level inputs, then run your front speaker wires into the sub-woofers speaker level input and then run a set of speaker wires from the sub-woofers speaker wire output to your front speakers. This is a common way to use a sub-woofer with a receiver that doesn't have a sub-woofer output.

Most powered sub-woofers have these connections, just check it out first before you buy one. They look like speaker jacks on the back of the receiver.

Let me know if you have any other questions.
