I have Harman Kardon speakers and subwoofers connected to a Denon AVr 1508 receiver. All my five speakers are working but my subwoofer doesnt work. I m pretty sure I have connected the subwoofer properly as far as the connections go. Kindly advice

It sounds like you overloaded the Denon avr with too much resistence from the speakers. Please check the total resistence of the speakers before you connect them all. Also check that the speakers or their wires are not shorted!

Hello
There are four possibilities that the subwoofer doesn't gives any aoutput. They are:

• Subwoofer's power not turned

on.

•The "Subwoofer" setting at

"Speaker configuration" is set to

"No".

•The subwoofer is not properly

connected.

•The subwoofer's volume is
turned off.
Go to its manual setupscreen, come to speaker setup, speaker confuguration, come towards Sub Woofer, select "Yes" and press OK.

What's the make and model of the subwoofer? It sounds like it's a passive (unpowered) speaker.

I seriously doubt your test mode worked fine on the subwoofer level adjustmnent.

Get a powered (active) sub.

No, you have to follow the procedures in the manual to inform the unit that there is a subwoofer, then select some parameters on how it is used depending on the functional sizes of your other speakers.

That would depend mostly on your subwoofer. There are some that slave off the front left and right speaker outputs and still pass the amp's power to the Front Speakers. That would be the only way that would ensure volume control.

Otherwise you have to feed a self-powered sub from the Tape Outs but that won't allow volume control from the H-K.

If your connected via the sub pre out on your reciever check your setting to make sure that it is turned on also if this is done you may try using speaker cables to by wire the subwoofer

you will need to go into the speaker setup and switch the sub setting from LFE to LFE+Main

hi there might be some problem with the link that u have hooked up with the speakers.

hi,
connect satelite speakers to the amplifier and connect signal cable (RC pin) to the woofer from amplifer ie subwoofer out from amp. ok na.

if this is ao powered sub, that plugs into the wall, there should be no problems, if it is powered solely by the reciever it may work fine but be sure you dont exceed amperage on the subwoofer.
