unless there are some other connectors that may be used, i would think that the issue would be resolvable thru the system settings menu, there may be a speaker arrangement setting somewhere in the menus. The Sub is a .1 setting like 5.1 or 7.1, perhaps even 2.1 where the beginning number is the speaker channels and .1 is the sub. I would think with the sub being on a mono channel it woul/should work with any setting. If there is any more info you could supply I will further research this issue and try to help you get the sub working.

I wish to replace a subwoofer on a surround sound system


In most surround sound systems the sub woofer is powered separately and uses a standard RCA coax connection to the receiver/amplifier.

Replacing is simply plugging in the new and reconnecting the coax cable.

Usually the audio signal is Dolby Digital 5.1 the (.1) is the LFE Sub-woofer. The connection is between the Subwoofer RCA connector on the amplifier and connects to the (LFE-Line) in on the subwoofer speaker.

Hope this helps?

Have you tried the "Simulated" surround setting?

If you don't get sound in "Simulated" mode then you have probably lost the surround channels.

If you do get sound then your "Media"
is not recorded with a surround "Track". or the surround "Processor" may have issues that need to go to the repair shop.

I have a Fisher RS-909 Surrond Sound amplifier. It has no "sub out" jack. I had the sub-woofer working in the past by wiring it as shown in the manual. The problem is that the system was in...


Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer.
surround sound unit sub woofer
left front: positive (+) <-----to------------->(+) left speaker level in
negative ( - )<- - -to- - - - - - ->( - ) left speaker level in

right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in

now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer.
sub woofer front surround sound speaker
left speaker level out (+)<-----to--------> (+) left front speaker
left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker

right speaker level out (+)<-----to--------> (+) right front speaker
right speaker level out( - ) <- - - to- - - ->( - ) right front speaker

Alright now that the wires are all over the place and plugged in
turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone

In dolby digital mode i can not get any voice volume. All other sounds are ok


Assuming that you mean Dolby digital 5.1, confirm that you have a center channel properly connected and perform the following;

Using the remote, enter the menu on the receiver and navigate to the selection labeled "LEVEL." Toggle through the selections until you reach the "CENTER CHANNEL". You will be able to use the remote to increase the volume of that channel in .5dB increments.

Lux Audio 5.1 home theater speaker & Yamaha HTR 5540 AMP


configure ur PC (both OS audio and third party sound driver) for surround sounds. control panel- sounds and audio devices - speaker settings - advanced - speker settings. so this done. make sure u select the 6 input channel - the button is on the right edge near the volume knob. near the vol button there are two buttons for selecting input type with up down arrow. from that u can select the input type this will be indicated on the top front indicator. but with the 6 input channel selected all selections are preceeded. if u select stereo mode u will have left/ right audio only.
make sure u connect the input right. connect from computer to 6 channel input. main, surround, center and sub-woofer.  connect the spekers to main (L/R), rear(surround) (L/R), center and sub woofer to terminal marked sub woofer ouput. this done select like i said before the 6 channel button. that should do it.

I suspect you have a bad cable, a poor ground or a bad
power supply inside the speaker amplifier. The amplifier
(inside the sub-woofer) could also be defective.
===
1) Bad cable or connector:
If the (braided shield/outer tube) of the coaxial input cable is
not grounded, the cable will pickup line frequency "hum"
from surrounding power lines, house wires, lights and
appliances.

This hum is then amplified by the speaker's amplifier
causing the constant bass sound you speak of.

Because the hum frequency fundamental is 60 Hertz in
North America, 50 Hertz in Europe, you hear it coming
mostly out of the sub-woofer, because the midrange and
high speaker circuits filter it out.

Check the input connectors, cable at both ends, wiggle
the jacks at a low volume setting to see if it changes.

Make sure that you are indeed using a properly shielded
coaxial cable.

A coaxial cable consists of a thin inner conductor, surrounded
by a flexible tube made up of a braided metal shield, which
must be grounded. This prevents hum from being picked up
by the sensitive amplifier inputs.
===

2) If the power supply within the sub-woofer's internal amplifier
is defective, the the power supply hum will also get coupled
into the amplifier and speaker with same results as above.

Power supply hum is typically twice the line frequency,
i.e. 120 Hertz, but not always, depending on what
component failed: Rectifier diode, filter capacitor, or
the voltage regulator.

3) Ground loops:
When you run very long cables between the source and
destination of an audio signal, multiple ground paths (must)
exist between the two points in space, creating complete
loop circuits.

Power line hum from the environment can (will) induce
heavy AC currents around these loops, creating a voltage
gradient across these cables, and in-between the end
devices.

Once again, this AC hum is coupled into the amplifier inputs.

Ground loops become a problem with cables over 10
feet long, and an astronomical problem for stage audio
engineers. To avoid ground loops, they must break
the circuit's continuity by using isolation transformers,
optical isolators, and/or differential input amplifiers.

So how long are your cables?

Most house stereo components are only designed to
handle 6 to 10 feet of cabling max.

30 feet is already asking for major trouble.

4) Feed back oscillation: This occurs when the output of
an amplifier is fed back to the inputs with a round trip
gain greater or equal to unity. The tiniest little electrical
disturbance is then amplified and re-amplified, over and
over again, usually at one preferred frequency, causing
the typical (ear-splitting) microphone squeal or howl.

In your situation feedback and/ loss of original signal
could be the result of mis-wiring the input cables.

Note that this is NOT as silly nor as unlikely as it sounds,
because many computer audio cards and even some
home stereo systems have re-configurable inputs and
outputs.

SOFTWARE configuration decides which jack at the
back does what !!!!

On my computer, for example, the Realtek audio driver
tries to automatically figure out what cable is connected
to each jack (usually it gets it wrong)

Using the Realtek control panel applet, I can then
manually re-configure the gray jack as input,
the green jack as bass, pink jack as center.... etc.

If this situation also applies to your system, please check
the software configuration. Connecting an output cable to
an input jack will certainly cause a lot of HUM and not
much music.

5) Finally, don't rule out internal sub-woofer failure. Unlike
the passive stereo/hi-fi speakers of days gone by, modern
multi-channel theater systems with front, center, rear and
sub-woofer speakers are internally amplified, with active
frequency cross-over filters and special effect/ surround
sound capabilities.

Usually, the large sub-woofer contains most of the
electronics, amplifiers and filters.

It feeds the other speakers, and it is controlled by
an external volume control module which can be separate
or built into one of the tweeters.

These sub-woofer electronics are prone to poor design,
overheating and early failure. (Even fresh out of the box
like yours)

If you cannot get it working, take it back to the store,
and make the NICE salesmen **** with it.

Good luck

Surround sound from Sky +


To upmix 2-channel sound (such as that in a TV broadcast) into 5.1 sound, press AMP and then SUR. DECODE until "PL II Movie" is displayed. This will give you "cinema-like" surround sound from a 2-channel source.

You can also assign this to one of your "Scenes" by following the procedure for scene assignment on page 26 of your manual.
