Summary
Built in regenerative power supply
Uses three R-core transformers (In total 260W ) and more than 100,000uf audio grade NOVER capacitors are used to ensure ample and smooth power delivery.
Separate class A PSUs power supply for regenerative drivers and audio signal amps .
Fully balanced class A Non- feedback ACSS analog design built by discrete analog stages without any OPA or coupling caps in the signal path.
Four-channel 100 steps digitally controlled relay-based volume control avoids channel imbalance and improves sound quality.
Supper Exponential Volume Characteristic, easy match the volume with different power amp and speaker .
5 analog inputs: RCA X2, XLR X2, ACSS X1 ( Even with RCA or XLR inputs, the output still had ACSS aviable)
3 outputs: XLR / RCA / ACSS
Static storage mode control software for avoid disturb sound quality , the MCU output once control data and save in the perform parts ,then stop output data until users next operation.

Un preamplificator in clasa A transparent, neutru, care nu coloreaza sunetul. Are sursa regenerativa( 3 transformatoare ), s-au folosit doar componente discrete, volum pe rele fara degradare a sunetului, impedanta foarte mare de intrare( nu incarca sursa ce este conectata inaintea lui cu sarcina inutila) si foarte mica de iesire ( conduce orice amplificator de putere ), etc.

Summary
Fully balanced design, the gain stages and pre-driver stages work in class A, built with discrete analog stages without any OPA or coupling caps in the signal channels.
The output transistor stages have supper excellent linear, it sound like the pure class A design but without the high heat of the pure class A design .
2 analog inputs: XLR / ACSS
Applies 80 pieces of ON Semiconductor transistors. Supports 250W X2 (8 Ohms) output.
The capacitance of the whole machine reaches as high as 260,000 uF, with two 800W circle core and two R cores transformers (Total 1700W) and separate power supplies for the right channel and left channels.
A total of 4 groups of high-quality class A parallel connection PSU's supply the gain stages.
Applies all audiophile grade components, including DALE resistors, WIMA caps, custom order NOVER (UK brand) caps, all audiophile grade input & output sockets and gold IEC socket.
The non negative feedback output drive stages had applied "Linear Fidelity" technology

Monoblocuri cu o putere mai mult decat suficienta pentru a conduce cele mai dificile boxe. Dubleaza puterea la fiecare injumatatire a sarcinii (sursa de curent fara compromisuri), are 40 de tranzistori finali pe canal, impedanat mare de intrare (se poate conduce cu orice preamplicator), primii 30W sunt in clasa A , etc.
Pentru mai multe detalii nu ezitati sa ma contactati. Prefer livrare personala si proba in Galati datorita dimensiunilor si a greutatii dar se poate discuta si trimiterea prin curier.
