Help!

[SonOfArathorn]

I have a Harman Kardon avr 154 and am hooking it to a Polk Sw505 12", I used a thx monster sub cable from the pre out on the receiver to the LFE (unfiltered) input on the sub and it worked for an hour until I accidentaly switched the power from "auto" to "on" and then it stopped working. Do I have it hooked up right? Do I need to connect it differently? Different cables?

[SonOfArathorn]

The manual for the avr says the sub output is filtered, does this mean I will have to get a Y connector and run the sub cable I currently have into that and then go into the left and right filtered inputs on the sub?
Sorry if these are stupid questions.

HOOK- UP METHOD #2 ( FIGURE 8)
This method can be used with electronics that include a “SUBOUT” feature (Figure 8). It is not recommended for use with compact sub/sat systems. Connect a single RCA cable from the “SUB OUT” of your electronics to the LFE input of the subwoofer. This input bypasses the subwoofer’s variable low pass filter and relies on the filter built into your electronics. If your “SUB OUT” is an unfiltered signal (check your receivers owner’s manual), use either left or right “Line Level Input,” to use the low pass crossover in the subwoofer. When using method #2, it is necessary to adjust the settings of your electronics as follows: Front speakers = large or small depending on their output capabilities; Subwoofer = “ON.”

Subwoofer Output:
If you have a powered subwoofer with a line-level input,connect it to this jack.(or any other external decoder) to these jacks. Connect the Subwoofer Output on the AVR 154 to the line-level input on
your subwoofer.


Based on what I read from your manuals, try connecting the sub cable to the left or right "Filtered Line Level Input".

Might want to grab one of these eventually:

If your home theater receiver has a single mono RCA subwoofer output and your subwoofer has left and right (L/R) RCA inputs, then this product can be used to split the signal to the L/R inputs on the subwoofer without degrading the audio quality.

What kind of speakers do you have?

[SonOfArathorn]

Thanks, I will pick some of those up on the way home for lunch tonight and try it.. Thank you.

[SonOfArathorn]

Speakers are Bose, got them from a friend, not sure what model they are, pretty new. Weird that it worked for a little while until I hit that switch, hope I didn't ruin anything on the sub, the lights still come on and stuff but no sound comes out of it.

Did you try turning the sub off,unplugging & letting it sit for awhile? Check the fuse( below the power cord input )?
Anyways, good luck.

From the title of the thread, I thought this was an announcement for a Beatles BD!

Me too!

When I go home for lunch and if the y connector etc doesn't work I will unplug and let it sit until I get home after work to see if that helps.
Only got to enjoy the damn thing for an hour.
Got 2 of the subs but didn't need the second, wish I'd have kept it now.

I responded to your PM. I will copy my response here for everyone's benefit.

It is possible that you may have blown a fuse inside the amplifier of the subwoofer. Check it to make sure. Radio Shack sells different type fuses.

You can connect a sub cable from the sub preout (LFE output) on the back of the receiver to the LFE input or the right and left inputs on the back of the subwoofer. The difference is that when you connect a sub cable to the LFE input, the internal crossover on the back of the subwoofer is disengaged and control is given to the crossover settings inside the receiver.

If you connect a sub cable to the left input (or right input depending on the subwoofer), the internal crossover on the back of the subwoofer is still active. You have to manually turn the crossover on the back of the sub all the way up to its maximum point. This in effect gives control of the crossovers to the receiver.

If you use a Y adapter (2 male, 1 female) and connect the sub cable to both the left and the right inputs on the back of the sub, you may gain between 3dB to 6dB of additional gain.

Last question before I head home to check this stuff...

Where is the fuse located? Are they easy to replace? How will I know it is blown? Sorry again if these seem like stupid questions, I am new to this.

Door below the subwoofer power cord input.
Yes.
It's a clear tube fuse, should be able to tell.

Bought a y, unplugged everything, checked fuse, it was good, turned it on and works like a dream. Thanks for everything guys!

[SonOfArathorn]

So, more detail.

I stopped at radio shack, got the y connector. Got home, unplugged everything and re hooked it up, pulled out the fuse, it was good, put it back in, and the damn thing worked great. Not sure what the issue was earlier as the only thing I did differently was use the line level inputs, but I had great sound before I did that. Crazy.

Anyway, once again I must thank the users here. This site has helped me out sooooooooooo much with my HT setup, and every question I've ever asked really.

Glad to hear you're back up and running! Enjoy!

Thanks man, it was a shame I had tocome back to work after I got it back up and running, just wanted to sit there and let the bass punch holes in my chest all night
