D-Fend

#1 Post by LelandCrooks » Sat Aug 20, 2011 7:19 am

I've been keeping an eye on these things. Think maybe it's time to jump. Would be perfect for the tubas/titans. And I believe they're going to be pretty affordable. There are several more videos, but nothing blows up in them. :twisted:

They won't be available until October at the earliest. They had to change them to incorporate a USB port, otherwise the average user couldn't program them. AFAIK the retail will be in the vicinity of $50.

Inside the cabinet, runs from speaker line voltage. An external model is in the works.

Does the dfend unit die when it sees that kind of voltage? ( haven't read up on it yet) I wonder how it sounds - if you can hear it working.

there are several videos but they do not quite explain other function than a protection circuitry (it is a signal processor also ?? ie xover maybe a phase correction like bbe maximizer )
There is a very thin line between fail and success. It is very thin so, why are you scared???

Around $50? What an investment! I do have 1U open in my rack, so a d-fend that's rackmountable would be sweet!

In one of the videos they dump a 6k lab gruppen into at clip. No ill effects to the driver or the circuit.

I didn't hear him say where all of that power is actually going. I wonder if they've tested it for hours straight.

apparently this isn't "dissapitive" blowed if I know how it does it but sooooo clever.

253, views on that vid, obviously breaking news eh Leland! It'll be all over the interweb in a week.

Mindblowing capabilities!

I got the impression the excess power is diverted to another chip that essentially ramps up to infinite resistance. Just like the amp is unhooked from a load. When I first talked to tech at eminence about them they told me it's very musical, not abrupt or choppy at all like a limiter/compressor can be.

I found it quite informative. That's only 10 minutes. Try five years for a BS. :lol:

Would that give a valve amp the heebie jeebies?
