Hey Mike,
One cause could be a faulty volume or balance control. Does the problem get better or worse as you turn the volume control? Does the receiver have a pre-amp out/power amp in connection on...

Hello,
I'm not a hundred percent sure, but I don't believe so. But, you should check with Polk.

Hello,
To begin advancing the time, once you have set the correct time unplug the AC power supply. Then, after a second, reconnect the power supply and the time will begin advancing.
You'd have to...

Hello,
Thanks for posting on the Forum. It is possible your TV is producing a small amount of noise that is preventing the auto on/off from working. You can test this by removing the audio...

Hello,
Those circuit path resistors look like Corning glass composition types. We used those on the original Dyna PAS 3X and ST70 mods, way back when. They were certainly an upgrade from carbon...

Happy Birthday, Cathy!

Hello,
If it is a true digital cable, the RCA plug itself would have to have a 75 ohm impedance as well as the cable. The dielectric used in the RCA plug would have to have a 75 ohm impedance at RF....

Hello,
With all due respect, I don't believe ignoring it is a good idea. The auto-calibration system is measuring something. There is a dip in the frequency response or a difference between the...

Hello,
The problem could be the relationship between the right speaker and the sub-woofer. The auto-calibration could be seeing a bass cancellation and reading this as "out-of-phase" between the...

Hello,
Are you looking for an RCA plug that will go on the end of a coaxial cable and have a characteristic impedance of 75 ohms? Not quite sure what you're looking for?
Cheers, Ken

Hello Andy,
I'm afraid it didn't scan very well. But, I have made a copy, so if you'll give me your snail mail address I can send it. You can contact me at kenswauger@tapepath.com
I don't think the...

Hello,
I can ask my wife to scan the article and I can send it to you. PM me your address and I'll send it.

Hello Andy,
The first amp is finished and the second one is completed except for cleaning and painting the AC transformer. The bell housings for this transformer have been powder coated and only...

Hello,
There isn't a parallel connection because the crossover isolates each section of the speaker from the other. If an incoming sound were 100Hz, for example, the low pass section of the...

Hello,
The speaker's impedance will remain the same no matter how many amplifiers you connect to it or how many speaker wires you use between the amplifier and the speaker. The speaker's impedance...

Hello,
The speaker level output, on the sub-woofer, will not be active unless you make a speaker level input connection to the unit. In other words, the only way to get a signal coming from the...

No problem! Take care.

Hello,
The Canadian manager is Walter Moser, a great guy. You can email him at wmoser@polkaudio.com and I'm sure he'll help.
Cheers, Ken

Merry Christmas, everyone!

Hello,
I agree with the other members, the amp seems to be in the bridged mode. That would be the most likely explanation that could cause the result. It "thinks" you want it to only produce a...

Hello,
Sometimes when I have a problem to figure out I go about it from the unwanted results backwards. In other words, I try to think how I could make what is happening happen if I wanted to. In...

Hello,
If the SDA cable is defective there won't be any sound produced by the SDA drivers. This would be the outside drivers of each speaker. You would need to check the SDA cable for end-to-end...

Excellent news! That's great!
Take care...!

Hello,
One approach is to take one of the resistors and bend its leads at right angles so it fits into the holes in the circuit board. Then turn the circuit board over and solder the leads to the...

I hope all goes well for you and your dog.
Take care, Ken
