TA-N7B
|
|
De gelijkstroom-eindversterker TA-N7B bestaat uit twee onafhankelijke mono-versterkers. Dit betekent dat het linker- en rechterkanaal praktisch onafhankelijk van elkaar worden gestuurd. Het voedingscircuit met 4 transformatoren voorkomt grotendeels dat de twee kanalen elkaar beïnvloeden. Het gebruik van V-FET en hoogfrequente bipolaire transistors zorgt voor een stabiele werking van de versterker in alle omstandigheden.
