Default SDA-400 Dual Mono AL Frame

I did not find on the market a dual mono with these performances in a 1Usize, with width 265mm (instead of 19. ") One more reason to be fascinating.
Even at full price (about 480 € vat included) remains in my opinion, a beautiful toy for music amateur, well compared to along with class AB, away from the € 1600 or € 3000.
--
I remind that these products are tested at least 5 years.

They are also used as a multi module for hotels and shopping complexes. (There is a small module (2x4cm), which allows use with the output line transformer 100V, currently running, even among some civil airports.
--------------
last, I am sure that this offer is not repeatable.

---------------------
Two in list at the moment:
18 Kit availlable.

Regards

At short, 4 CH

Default SDA-400-Kit-2

Hi,
The Kit-2 is composed of the components in photo (includes 30cm 10Pin flat cable)
Amps well tested and working at 500w rms (4R). with absolutely no problems.
The two sda-400 are electrically separated, each is complete with regulators LM317/337
The price € 110 + shipping (fixed at 22 €)
These kits (and others that I will put) can be shipped in 1 day because ready
Just a curiosity (the pcb input are high-cost (twice) because they have the solder-based resin and percentage of silver on layers.

Regards

Thanks AP2!

BTW, If I wanted to do a 6 channel amp in the near future, could I use the components you sent me and add some SDA-400 to the SMPS in my current kit? If yes, how many modules can I supply with a single SMPS (I believe I had read 3?) and what would be the max output into 4R per modules?

Thanks
Do

Hi,
In the original, an MDA-400 can power a SDA-400 and ensure 2x240w at 4R perfectly (it was developed for this) in fact, the MDA-400 has the power supply bus for one sda-400. of course, each module has its own on-board regulators lm317/337. Now with the new release of DPS-400 (which is the section smps) and pbtu-3, we have improved transient response (in terms of current). then no problem.
I suggest also the possibility (see ch 4) to leave an MDA for the sub, and use the 4 channel version consists of: 2xsda (double) +2 xDPS400. no heat, no noise, perfectly in range of high fidelity. I hope that some see well these modules. are complete of all protection,relays with gold-plated contacts for output also.

So what you're telling me is that MDA-400 that I will receive can handle nativelly a SDA-400 but you recommand using the MDA-400 for sub and the 4 ch version for the rest?

My sub is already powered by a 2000W Class D amp so I would use the channels for center, rear (L+R) and rear surround (L+R) or different configuration possible like center, front (L+R) and rear surround (L+R).

Can you PM me the price for the 4 ch kit?

Thanks
Do

Hi,
I now know the type of system (I thought of as multi-way stereo).
You can use 2xMDA-400 as front and / or 4xSDA-400+2xDPS-400.
Just for this configuration, I have prepared the kit-3. which consists in 4xSDA-400 in vertical (height 60mm) and two DPS-400 side by side. this assembly is complete with aluminum parts for mounted vertically and needs 2U case.
Or 2xKIT-2 + 2xDPS-400,depends on how you choose to Mount.
All are plug & play,complete of the input board (2CH each). this greatly facilitates mounting clean, no noise problems.
I will show this kit in the next few days.

Note:
If not differently specified, at this price around -50%, there are 10pcs 4CH (complete with smps) and 20pcs as stereo.
The problem is not the quantity available, but the price may be unfair to the market. is different, it is limited to a promotion.

Regards
