It all depends on the subwoofer; powered, or not powered. Most receivers have a low level output connection, 300millivolts: via an RCA type jack, labeled Subwoofer Output. With some of older subwoofers, you connect your speaker terminals from your Denon, to the subwoofer. From the subwoofer, you connect the output terminals to your front speakers. For more infomation, please contact me at audioserviceclinic.com. Thank you.
Connect a second coaxial cable from the RF OUT jack on the
surge protector to the input on the cable box or satellite receiver. If
this stops the hum, congratulations: You're done.
Unplug the subwoofer's electrical cord from the power strip
or wall outlet if it is connected to the same circuit as the AV
receiver. The amp in the AV receiver and the amp in the subwoofer are in
conflict over the grounding of the electrical circuit.
Plug the subwoofer into its own surge protector and connect
the surge protector to a different wall outlet than the AV receiver
Disconnect the subwoofer cable from the back of the sub and
the AV receiver if all other measures fail to stop the humming. Reverse
the plug connections so the plug that had been connected to the receiver
is now connected to the subwoofer. Turning the cable around may solve a
problem known as ground-loop hum by reversing the shielding wire inside
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
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
• 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.
Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.
Things You'll Need:
Home theater receiver Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores. 2 RCA subwoofer cables 2 subwoofers
Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.
Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..
Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.
Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.
Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.
Tips & Warnings
Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.
Disconnect the subwoofers from the power supply while making the audio connections.
I'm not sure what you mean by "connecting the Subwoofer connection to my Panasonic Home Theater System"
If you want to watch something on the Philips and send the audio to your Panasonic Home Theater you can buy a VGA to AV Adapter Cable. Just connect it to the back of the Philips HTS3450, get an AV cable (red,white,yellow) and run it to the Panasonic.
be sure that the projector you have is in the correct mode(ie.av,scable,tv.etc...)then make sure its in the right mode for say if you want to use the avs instead of the cable(ie.m,d/k etc..)this should solve most problems especially if you bought yours in china like i did the instructions were verry,verry limited on information.
