Hi,
"The crossover was used in a mid-1980s CES show with the JBL Everest DD55000 loudspeakers"
Who remember this demo?

He may have a problem selling it - how many people are there that:
1. Own a pair of Everests.
2. Want to active biamp them.
3. Don't want to adjust anything except high and low pass gain.
4. Don't mind a prototype piece.

I'm sure it is a fine sounding crossover, but in the end, he states it is a 1khz 18db/octave crossover. For that money, a much more flexible Bryston can be had on the used market. Interesting piece, but strictly for the acquiring collector...

I own an LNC-2 also. I find it to be very good at it's job, it adds nothing, subtracts nothing from the sound. It gives a pretty good thump at power-on, so you need to turn on the crossover before turning the amps on.
One like mine just sold today on ebay for 1005, so this seller may be asking too much for his. The schematics or information about how to change the frequency do not seem to be available. I've written to Levinson and they don't have anything. The Fischer Camac connectors are a problem, you have to make your own interconnect cables. It's not a big problem though, if you can solder and follow directions.

Thanks Don
I allready got them from suiza, getting ready for the soldering operation:blink:
Just happen that all my inter connectors are weird fancy ones directionals, battery plugged
etc... im not sure if Im going to be capable of connect the solders ok
Im thinking of DIY a new set instead of cutting a fancy one.
Any other tip.. how about connections? just in between de dac and the amp ?
anything else ?? these will be my first try so any help is great
Regards

I used regular RG-58 coax cable, this is what the camac connectors are designed for. At the other end I used Neutric RCA plugs. You can tell peple that your interconnects are rated to 2ghz.

Looking at the Belden catalog, I think I'd pick the Belden 8219. Stranded center conductor and tinned copper for both shield and center, with no foil layer to make the assembly harder. Any wire vendor will have something similar to this. In my past career as a communications tech I must have built hundreds of RF and video cables from this stuff. None of the electrical characteristics will make any difference at audio frequencies. The kind with the solid center conductor is easier to assemble, but not as flexible. The cables that Levinson supplied had a gray colored jacket, so you could try to copy that if you like.
