EP2500 dip switches

[saddlesore]

Please help. I've had my 4x18" Fi IB running for a few weeks and am really happy with its performance.

After reading tens for forums about "how to configure the EP2500 dip switches", I can't find two articles that make the same recommendations." Whenever this topic comes up in forums, there seems to be pages and pages of babble, but no discrete instructions.

In short, I have the drivers wired (series/parallel) = 4 ohm load
Two pair of speakers, each pair wired in series, then wired in parallel.

If anyone else has a similar setup, I would appreciate if you could share how you have your dip switches set.

Thanks,
Steve

There's no benefit to running the drivers as a single 4 ohm load.

Wire each pair in series this gives you 2-4ohm loads, run the amp in stereo one pair of drivers on each channel.

The big DIP switch on the back of the EP-1500/2500 amps have +/- marks molded into plastic housing. On some amps these molded in markings are opposite the settings that are screened in graphic on the back of the amp.

If you're using one of these amps and you don't think you're getting enough low frequency output CHECK THE POSITION of the selector switches on the back of the amp.

DIP switches #1, 3, 8, 10 need to be turned OFF, since there is confusing information as to which position is OFF, try both positions. In one position there's going to be a lot more bass than the other.

When #1, 3, 8 and 10 are OFF, it doesn't matter what position the 30Hz/50Hz switches (#2 & # 9) are in since they're deactivated.

Switches #4 & 5 should be in the stereo mode, #6 & 7 should be in the Bridge mode off

Thomas - thank you.

Dip switches #3 and #8 (low cut filters were on). Yep, much better now.

Sorry about the silly questions, but setting dip switches that are sometimes "off" when flipped to the right and sometimes "off" when flipped to the left, is tough without any vision.

Thanks again,
Steve

BTW... in the short-term I'm stuck with a single 4-ohm load. My manifolds are glued, screwed, and pounded into position, trimmed, painted and framed.

I'm confused with this. Don't I want a single input to output to both channels, thus turn 4 & 5 on? Thanks.
