Harmon Kardon sub wont work

I have a Harmon Kardon avr 635 and a htks 14 surround sound system.It has a 200 watt 12 inch sub that has never had problems.It has three inputs; a right,left and a line level in.I have always had it connected from the receiver to the line level in and it has been fine.That input is not producing any sound.I connected my ipod to the right and left jack and that worked.I switched the cable out and that wasn't the problem.I am even willing to get a multimeter and take it apart if I need to.i just am not sure if it is the receiver or the jack on the sub.HK put me in contact with a repair company that is 90 miles away,not open evenings or weekends, and said it will be a minimum of $150.Any help would be greatly appreciated.Thanks for your help!

SOURCE: sub thumps repeatedly

since it still thumps i suspect the speaker is ok, but i suspect you have an electronic problem in the amp. since it is a powered sup & has the ability to auto turn on it has electronic circuits inside, take it to a service center for an estimate

SOURCE: subwoofer connection

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.

SOURCE: connection between harmon receiver and A-bus in wall speakers...

There is a CAT5/RJ45 A-Bus interface on the back of the HK AVR 435. That needs to connect to your A-BUS "hub". HK has two hub products: ABH-4000 and ABH-4 (older). Then CAT5 cable can be run from this hub to Wall-installed room-specific controls. HK has the AB-2 product, but any ABus compatible wall control will work. From the wall control, you wire regular audio cable to the speakers. So, some of the questions/issues to solve are: where do the existing wires go that are connected to the in-wall speakers? Typically that location is where to place your in-wall volume and source controls. Then the CAT5 gets wired from those controls back to the hub. And all that's required is a single CAT5 from the AVR to the Hub.

SOURCE: how do i connect my boston acoustics pv800

You need to use the LINE LEVEL connection on the pv800 (usually a rca type connector cable) and run this cable into the back of the HK 520 Subwoofer PRE-OUT connector, be sure the HK Receiver menu speaker set-up option is set to SUBWOOFER "YES"

SOURCE: I have a Harmon Kardon

I have this exact setup. 901s are my Mains.

The AVR247 has PreOuts on all of the channels.. No jumper to remove either. Just get a power amp or two and place the 901 EQ between the AVR247 and the Power Amplifier.

The inputs may be assignable on the Harman Kardon. Make sure you have selected the proper analog or digital input type for the cable you are using.

Harmon kardon 745 displays "unlock" no sound for tv or movies


I also had this UNLOCK message on my Harman Cardon AVR 130.
The reason for this error was - in a hurry I've plugged the optical input into optical OUT! Double check that your connections in the back are correct and hopefully it fixes your problem.

Cheers,
Sergey
