Velodyne ULD-15 series II X-over and cable ??? s

-- I've got to crack open the external amp / xover for my trusty Velodyne and change the crossover chip from taking inverted inputs to taking standard inputs due to a system config change. Problem is, I can't find my documents on how to change this on the chip-- you either add or remove a resistor...

SO, anyone out there have an owner's manual and can look for me? It'd be appreciated.

BTW, I already have a call into Velodyne's ULD series guru Dave, awaiting a call back- so he may be able to solve part 1 for me real easily.

Part 2 is, has anyone experimented with replacing the silly little lamp cord power cord on the ULD series amp? The amp is allegedly a 400 watt class B design, and the power cord doesn't appear suitable for a small desk lamp...

Any input / experiences swapping out this (hardwired) cord would be appreciated. I'm not sure I'll bother installing an IEC socket, I'll probably just solder straight to the existing connections.

WOW!

Dave Santos at Velodyne returned my call not only same day but within a few hours, then faxed me the info I need. I almost feel bad for doubting anyone there would help out.

So, now we're down to just the powercord- any input?

Hmmm. Nobody cares. Fine. Here ya go anyhow.

I put a new power cord on my sub amp last night. El Cheapo 12/3 power cord from Home Depot and a decent plug. It's only a 2 conductor cord, but they didn't have 12/2 power cord. Anything would have to be a huge upgrade from the 18/2 factory cord. I also soldered a connection on the hot side that used to be a crimped blade connector "slip on" and installed a gold plated audiophile grade fuse I had laying around. Total investment $7.50, a grommet, 4" of solder, 3 zip ties + 20 minutes.

Improvement? HUGE, it sounds like an 18" sub now. My entire house shook! The blacks are blacker, the background quieter, the booms boomier and my dishes have never been cleaner!!!

Nawww. Just kidding.

I do think the old cord was "strangling" the amp a bit, however, since the first thing I had to do was go down 2 hash marks on the volume dial on the sub amp. The sound quality is not noticeably different at this time, but it is a sub after all.

Maybe if I cryo the volume knob...
