Descripción

HFA-1200 Amplificador de potencia estéreo

The HFA-1200 is a dual mono Class AB stereo power amplifier. Each channel has its own 500 VA toroidal transformer, its own rectifier bank and its own heatsink, so the two channels never share a ground return or a supply rail.

The input stage uses a low noise JFET differential pair followed by a relay switched resistor ladder, which keeps the signal path short and the noise floor at -112 dB. A slow start circuit limits inrush current and protects the output relays.

Every unit is burned in for 48 hours and measured before it leaves the factory. The measurement sheet is included in the box.
