SDA-400 Professional multi-way

[AP2]

is it important for cooling (connecting to bottom plate) ?

For quiet home use, not required.

 

[tinitus]

OK
I might build complete new alu chassis
or maybe do my favourite plywood thing
that way I can extend the depth of my present chassis
But I'm indecisive, as usual
got most of it sorted so far, and will let it cool down for while

but definately have to match my bass guitar mono amp 😀

thanks

thank you for the confirmation!
FYI , I will use a Kit1(52v) + 2 othrr sda for 4 woofer, then the 2 remaining dps (42v) for the 4 VSSA, so 8 chanels in total with 4 dps, 4 sda and 4 vssa

Ah.. yes, then i send 2xDPS-400 (as KIT-8) for VSSA amp at 42V with +12V regulated well filtered, REF to GND. (this mean that not running with a SDA-400). you agree??

Well, at end I'm sure that you change ..case eheh!
Then...you have listen your guitar bass with mda-400 at end??

maybe I will play bass guitar on my stereo, or listen to music on my bass rig .. not sure which, or how 😛

but I may need to think about some exstras, like signal line out etc

and yet, for digitial music signal/source, the future seem to be D/A digital preamp

Later today, I will show an important audio measurements, on a Kenwood KA-4520 amp 2x110w rms. (fft + thd at 3w and 50w) before replacing the original transformer with two DPS-400 at 52V + PBTU-3 (one for smps) vers.2x10000uF.
various photos before and after the change.
Listening is completely different a lot , power increase also to 150w rms. 🙂
As write in various forum, this amp have very generous trafo also.
This simple two measure, definitely eliminates all doubt. (if someone have)

P.S. Amplifier as virgin,open for first time as new.
Listen in Audio room with Phono MM. zero problem and noise,
the dynamic is great, very fast amplifier as 50Khz.

Hello,
yes :
one kit1, standard in 52V

the other kit 1 spread like this:
-2 DPS in 42V with V2 and V3 ref GND , (like a kit 8 in fact)
-2 SDA 400 (which will be connected on the DPS of the first kit 1)

for this second kit 1, I do not need the PCB with POT and XLR so you could save money if you whish 😎

😉

Hi, strange, long time passed, i check well today later and send pm.
Becouse, some have received as promotion 1xMDA-400 and not have show even simple "thank received", I thought you had already received.

Hi. Have you checked? I not received pm

 

[AP2]

Hi. Have you checked? I not received pm

Hi Baga, I did a search on POST-IT, your parcel is in break (came back) is located in the postal depot to return to my office.
likely an error in the address? however, since you're very interested in it, I can send another MDA-400 as promotion test x Monday for sure.

Just now noticed it's dangerous to have two input plugs with mains voltage 😱

not good 😡

Hi,
Dangerous yes,especially if it is connected to the speakon and the other remains free. remove the traditional AC Main, then.
Populate well the rear panel, what type of connector is the couple in the center (copper)? use for?

 

[tinitus]

.. remove the traditional AC Main, then.

I'm on it 😉

(btw, it's Powercon, not Speakon)

... what type of connector is the couple in the center (copper)? use for?

ordinary hifi speaker terminal

with 3 speaker terminals I can test 1ohm load 😀 ... nah, just joking 😛

 

[tinitus]

moved the Powercon and fuse holder ... I'm fast 😀

it was never planned exactly like this, but I now have this 'setup' in mind
