Hi,

I just got a Harman Kardon DPR 1005 and a Klipsch 7.1 system with an
SW12 II subwoofer.

The sub has a L/R RCA and otherwise has inputs for speaker wire. I have
a connection from the LFE preout on the receiver to one of the RCA
inputs on the sub, but I get no signal whatsoever. If I hook my cd
player straight into the sub, I get sound, though not all too much.

Any suggestions? I have tried setting my front/center speakers to both
loud and soft and have the receiver set to output LFE and L/R bass
frequencies to the sub.

Any ideas on tests I can do to determine if the receiver is actually
outputting anything and/or if the sub is blown?

Thanks,
Larry

What I meant to say was that I've tried setting my front/center
speakers to both large and small, with no result for the sub, though on
"large," I do get bass frequencies from the front/center.

Check out the various surround modes on your receiver. Some
activate the LFE speaker, but some might not.

I just tried many different modes and can't get a sound out of the sub
in any of them...

Obvious checks - is the sub switched on, and what's the sub's volume setting
set to? Is there a switch for line/speaker input. and is it set correctly?

You can check the output from the receiver with a digital multimeter set to
AC. It might be easier if you have the receiver playing a 50/60Hz sine
wave.

Many Home Theater receivers have a "test" mode that will switch a noise
source to the various speakers. If you have subwoofer output using the
test signal, at least you've proven that the receiver's subwoofer
output and the subwoofer actually work. (perhaps the receiver's
subwoofer level is set very low?)

Well, after swapping cables, trying many modes and settings, it kicked
in and now it's working great! Thank you all for your time and
consideration. I really appreciate it!
