Completed 6ch Amp

Just wanted to share my implementation of 3 boards.

It's 700VA Toroid with 6 Secondaries at 27 Volts. (special) Softstart from Per-Anders.

Balanced XLR-Inputs

Hifi2000 chassis from Audiokit.it

Hot Stand-By with Signal sensor.

40 cm Fischer heat-sinks.

It's used in a 3-way active XOver setup.

An externally hosted image should be here but it was not working when we last tested it.

I like the sound very much, it's crisp and clear, but still a solid bottom.
 
OKI, I get it around the "lampsladd" :) Will fix, it's.

"Shielded input wire" ... do you mean the connects from XLR --> Board input? ... Currently it's twisted with grounded wires so it should be OK shielded anyway.

It's very silent without signal, not the slightest hum or noise.
 
The case is a Hifi2000 "pesante" with extra thick 10 mm Alu frontplate. I bought it from Audiokit.it.

The sound is very clear and crisp. First impression is thin, but it's after a while you realize that it's quite powerful and has a great deal of punch in the bass as well. I'm using it in a tri-amp setup i.e. each amp stage drives one single driver directly.
 
It is project of " CompromisLessCrossover " - CLC1 - with variable configuration ( 2 - 2,5 - 3 - 3,5 - 4 way ), analog - 24 dB/oct, with many setups ( switchable frequencies, phase correction, speaker correction, baffle step, subsonic filter etc... ). Project is still in developement, but I hope it will be ready this year... All is made by small modules, which are usable also in other equipment ... This is all in short... :cool:
