Ther should be a diagram in the left hand corner of display of speakers hooked up, make sure sub is shown right under the left right (and possibly) center speaker icons. under adjust, there is a subwoofer volume level. Under settings there is sub (yes, and no for on and off) there is a sub crossover frequency, and i believe there is also a "LFE" att, which is another subwoofer level.

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..
Take care and please Remember to rate/vote and give me 4 Thumbs Up

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.

I have the Subwoofer plugged into the output and have it turned ON but it's still not working!


It only drives a self-powerd sub.

The manual...

http://www.retrevo.com/support/JVC-RX-8010VBKC-Receivers-manual/id/315dj079/t/2/

Page 17:

Setting the Subwoofer Information


Register whether you have connected a subwoofer or not.

Before you start, remember....

• There is a time limit in doing the following steps. If the setting is canceled before you finish, start from step 1 again.

On the front panel ONLY:

1. Press SETTING repeatedly until "SUBWOOFER" appears on the display.

The display changes to show the current setting.

2. Press CONTROL UP / DOWN to select "YES" or "NO."

• Each time you press the button, the display alternates between "YES" and "NO."

YES: Select this when a subwoofer is connected.

NO: Select this when no subwoofer is used.

Note:

You cannot use SUBWOOFER OUT ON/OFF on the front panel (see page 14) and adjust the subwoofer output level (see below) when "SUBWOOFER" is set to "NO."


Then continue with setting its relative level and other things.

How to connect subwoofer


This manual discusses it somewhat.

http://service.us.panasonic.com/OPERMANPDF/SAAX730.PDF

Basically, feed the self-powered (active) subwoofer from the Subwoofer Out. There does not seem to be a way to adjust the subwoofer output to match the rest of the speakers because the sub out is muted during the adjustment procedure.

Another way would be to refer to page 15. The note at the bottom right suggests your subwoofer might accept full range speaker level inputs. Refer to the manual for your sub. I believe they mis-printed it and meant "active" subwoofer, as simply wiring a passive (unpowered) sub across the front speaker outputs might cause some amplifier overload issues and you would have no way of balancing it anyway.

I am trying to hook up a powered sub woofer to a yamaha rx-v461 and i dont know what cables go where on the back of the sub there are two speaker ports and there are two plug ins but each speaker port has...


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.

Cant get bass, fuse is fine


You don't say if you've configured the Receiver to know you have a subwoofer (under Multicontrol - SUBW YES). Unless it knows about the Sub it won't send anything out that single "preout". You can get an RCA splitter to run that single output to both inputs in the Sub.

Just as an experiment, temporarily run one a pair of cables from the REC OUT to the Sub's inputs and tune an FM station to prove the Sub amplifier is alive. If it's still silent, it's dead. If there is sound (muffled) you need to go back to the Receiver to figure out why the Sub Preout is signal-starved.

No sound out of subwoofer


Connection from receiver subwoofer output jack RCA plug male go into your powered subwoofer low level input with other end of cable, then you need to select Subwoofer YES/NO on the JVC receiver speaker setup menu option, select YES if this is a powered subwoofer you are using, should power up the subwoofer, may have to adjust a test tone balance for multi speaker output also, try trimming up on the subwoofer channel to initiate the signal on if the sub has an auto-on feature.

Subwoofer: Active or non active?


Hello Smegboy,

Yes, you are right. This receiver is rated at 100WRMS output in all 5 channels (2-front, 1-center and 2-surround) while in Dolby Pro Logic operation. The subwoofer output is line level only (not amplified), which means you need a powered subwoofer to be connected to this output. A non-powered subwoofer could be used but, you need an additional amplifier connected to the subwwofer output from the receiver to drive it.
Let me know if this helps.
