Innovative Monitor Studio Power Amp D Class (120Vac)

AudioPower · « **on:** 26 Nov 2015, 09:46 am »

Hi, I'm new and probable mistake for my post..I thinks due to labyrinth eheh!

Well, We want present a innovative (120Vac) D Class power amplifier for Amateurs use. (or studio monitor)
It's DPA-200/F-LV. first new is the "direct conversion" in the 120Vac circuit (not use capacitors doubler in the high voltage section).
the smps play as "differential regulation" with response time = 150nS. (smps integrated, use the "UR" system as our DPS-500/UR)
The power amplifier have only 27mm height, able to push low reactive load as 450w (2R).

A bit complex in the smart protection and in the modulator (it' not self oscillant).

I think it can be interesting, even under the price promotion.

the pic can give other information about the components and the finishing of this form.
Moderator please direct me to the right thread, if I'm wrong.
My interest is only to present this amp professional.

regards
Roberto

AP Measurements?

AudioPower · « **Reply #5 on:** 27 Nov 2015, 10:35 am »

Hi,
Thanks for the welcome.

To publish the measures(as various graph), we have to wait on December 1.
I consider important to describe a minimum of history, in fact this amp, is derived from the twin DPA-200 / F (230V). Long-tested with good results.
Personally, I am too fond of high-fidelity, I tried to cure some good aspects, much more important than thd (in my opinion).

This series DPA-xxx include all the functions, such as an amplifier finished.
Ah..yes, for sure you can fit in 15min. a dual mono ... I hope it is not only this, the strong point.

The package that we are preparing for promotion(Dual mono kit), include any accessories, as the output cable special silver as multi wires (8x0.6mm) each, with XLR input board, LED functions, etc etc.also the AC Cable 30cm, 2x3.3mm silver[/i]

Thanks & best regards

Roberto

Note on the components.
We guarantee European components, selected with the same lot number.
All the caps 105 ° : Rubycon MXC series in the high voltage, and Panasonic in the output DC
The rest is visible.

Good morning,
The picture is not good, but enough to see what is in the kit.

The DPA-200 / F-LV was derived from the twin, which is distinguished by the color of the PCB (Red).
If everything is ok, the promotion should start on December 1 to December 30 2015.

I am available to any questions with pleasure.

Return with a set of audio measurements.

Regards

Roberto
