Axiom Home Page Forums General Discussion Technical Questions Connecting EP500 to line output of receiver.

Yes, I'm pleased with the speakers, even if the sub turns out to be less than fully functional. I also got four QS8s in place of the the QS4s that were advertised.

A couple other questions: Is there somewhere I can find an older version of the manual? This sub is model "EP-500", serial 5050001, bought in 2006 according to the seller. And, related, what do the settings on the Trim control do? (Remote, Flat, Half, Full, Load)

Was the guy you bought them from even the original owner? How could you not know what speakers you have especially if only about 3 years old.

The trim control adjusts the frequency response of the sub kind of like using EQ but with preset settings. Flat is a flat FR, where Half and Full are designed to help compensate for subwoofers in general having FR issues in small rooms. Load is supposed to be for firmware updates though I’ve never seen one yet.

I’ve used the Half and Full settings to boost the FR at around the 40Hz range in two rooms where I had large dips due to room modes.

Wow, that's definitely an old EP500 amp.

It was a gal, and I gather her ex bought them. Well, I think what happens is that folks not really interested in audio and video gear categorize equipment by brand and general functionality. But sometimes not by model or year. I see quite a few listings on Craigslist for "Sony 5.1 speakers", e.g., as though Sony only ever made one 5.1 speaker set. "A nice 42 inch Samsung flatscreen."

Thanks for the info on Trim.

By poking around, I found an older manual version: Older EP500 manual.

So many changes I've noticed to the ep500v2 amp. First the 3 accessible round fuses were omitted, then the crossover was changed from bypass (100hz) to 150hz, then the volume level knob was desensitized (is that a word?), then the replacement of the trim knob with a subsonic switch (which the older ones already had the subsonic roll-off program built-in), and now a totally new look for the amp, which now requires an rca-phono adapter jack that plugs into the xlr?

Greg,

Did you find that system locally? Just wondering.

Yes, locally, on Craigslist Hawaii/Oahu.

This is what they replaced my amp with. I just bought mine and received May 2009 - so these updates have happened between then and now.
