Looks like a very clean job :thumb:

When I have time I will be building one og those, maybe with some subgroups to connect my other DIY projects....

AMAZING!!!

I love it, the idea of using turret board for your passive wiring, brilliant! No neat, and the specs look great... I want one!!!

Cheers

all my racks and pannels are custom made by www.KID-broadcast.de to my specs (because I hate doing mechanical work ...)

well, it's the only way to fit 24 balanced inputs in a 1U rack

it's an easy and cheap project - just build one :green:

Thanks Volker!
That was the link to the case I´ve been searchin´for all the time. I hate metalworks, too and I´d really love to pay bucks for a finished box. I´ll check them out. Can you give me an idea how much you enclosure costed?

The summing amp has impressive specs. Nice one :green:

Jens,
I don't know the price for this one, but my GSSL was around EUR 160,- (netto). and you have to be patient with these guys ... :twisted:

mik · Feb 26, 2006

are those the same zero ohm cards someone was selling in the black market, or something entirely different???

Looks freaking spectacular however

Very nice stuff!

jensenmann · Feb 26, 2006

Those were different ones. I sold some Lawo V975 summing cards but Volker is using the Neumann V475 versions. Both use zero Ohm summing. Anyway they play in the same league.

[silent:arts] · Feb 26, 2006

I used the Neumann V475-2B, recaped it and disabled the LP filter.(otherwise you would have -20dB at 40 kHz)
