Hi ,
You can connect direct on CN (input pcb) without res.
Right "CLIP" is better orange High-Light. (others as generic LED)
For on/off, you can use simple 1-pole permanent switch, connected on CN5(2PIN) and add a Led in parallel,via resistor 470R-1K depeand light.(see polarity on CN5)
Blink at start and immediately turns off. Simple scheme is on thread.

Hello Amateurs,

The Mda-400-Kit1:
Complete of all in photo (need only a empity case 1U)
The MDA-400-Kit2:
Includes stereo case, 4 color top/bottom cover available (of 6 final)
-----------
Power Output 2x340w (4R) 2x520w (2R) SIN 1Khz
-----------
Both kits, they use anodized aluminum frame, which allows easy mounting in any case 1U, as well as offering a product tested in terms of EMI / RFI shielding and thermal performance. (the maximum excursion as Delta, is 25 in any condition of use.
The kit also,includes 4x special wire (for speaker connection), made ​​of pure copper 2mm diameter, solid (very flexible), covered with a polyester sheath.

This ultra compact dual mono, has a current into the load of 32amp peak per channel, perfectly repeatable as audio transients.

....A good reason to listen good music or... impress your friends

P.S. I want to take this opportunity in this forum, so I need a list this week, just to know if I can keep confidential the 20 kit that I have.
Needless to say, in a week, I received from 'Italy 60 order (1 week), do yourself a little deal.

I received my package :-) ... Impressed by the packaging, very nice...
Click the image to open in full size.

The quality of the whole is more than excellent, I would quickly connect all this to apreciate this quality amp but ...
But i'm missing some connectors ...
There were only 4 parts thereof, (and I've broken one ...)
Click the image to open in full size.

And no molex 4 pin...

The sink hole is too small for the screws;
Click the image to open in full size.

Ok these are just details ...
I have to buy some components for another project. I become crazy wenn i try to find everything I'm looking for ...
Roberto can you give me references/name (or a link) of connectors for the Colour Coded Ribbon Cables because I can not find this product ...

Is there a need for a heatsink for sda400 module?

good day,
Dear Darb, is a cruel fate, nice products with some stupid mistakes, I am mortified by these happened.
For the heatsink, this is a defect in the mechanical processing.
Ah .. no doubt about that, right now I have a person only for the control of all the parts, one by one before the closing of the package.

To see the connector IDC10PIN it.farnell.com/amphenol/t812110a100ceu/socket-idc-2-54mm-a-10-vie/dp/2215232.
For the Heatsink, you have the possibility to increase the hole at 7mm diameter x 6 mm depth?
------
The SDA-400 does not require a Heatsink, if you can find a simple "L", it can make better fitting.
-----
What kind of speakers do you have? The SDA + DPS-500/52V, has considerable fast high-current on load....you can imagine, only when you listen to
P.S.
If you do not have urgency (as one wek), I can ship small packages, via Post-IT.
Obviously replace the Heatsink also.
Your country is strangely expensive via UPS, I paid 60 €

Thank you for the information Roberto,

I have found the amphenol connector one minute before you reply me... @ farnell...
But i can't find the "molex" female 4 pin that goes on the sda400... I not understand, it's a common connector...
Did you have a link on farnell web site?
For the heatsink it's not a problem, a friend can help me for making this hole a little bit bigger

Don't worry for this very little mistakes...

My speaker are DIY and i am going to make a system with active multi amplification. Your sda400 will be used for bass, for this I need a amp with good damping factor and here I think your system will be perfect. In the meantime I will use your amplifier only... when it will be ready ...

Is a normal female connector, 2.54 step,in line, made ​​by many manufacturers.
We buy directly, so I do not know at the distributors good for DIY.

I find this at Mouser. seem that molex changed the shape..

Hi,
The dimensions can help to choose a enclosure different. in this forum and on ebay, there are some nice case compact, cost around U.S. $ 30-40.
Thanks to the frame in AL, mounts easily with 4 screws.

If Your case have 50mm internal height, PBTU-3 can assembly in vertical also,this reduce depth -25mm

Regards
