Vendo amplificador de auscultadores, com as seguintes características, tal como anunciadas pelo fabricante:

Balanced / Single-ended connectivity
For its connectivity, the A50 is both simple and very efficient. It integrates a single stereo RCA input but has 3 headphone outputs, one of which is balanced on a 2.5mm jack connector. A stereo RCA line output is also available on the back of the unit.

Aluminium case
The components of the A50 Topping are hidden under a beautiful and robust CNC machined Aluminium housing. It is also designed to effectively dissipate the heat released by the power supply and PDOs.

Digital volume
The A50 scans the position of the volume knob and transmits the data to the JRC1195 controller for a precise adjustment of the volume level. This chip also provides a perfect volume balance between the left and right channels.

AOP
The amplifier includes a pair of LME49720 PDOs mounted on a DIP8 bracket. It is therefore possible to easily replace these PDOs to adapt the sound reproduction to your listening experience.

Regulated power supply
The power supply circuit of the A50 is stabilized by low noise TI TPS7A33/47 linear regulators. These high-performance chips provide clean and stable power to all A50 circuits.
