NAD Preamplifier C275BEE

Art and Sound

When it comes to a NAD product, the utmost attention to detail is paid. From the heavy gauge steel chassis to the advanced power supplies and copper buss bars, the C 275BEE represents all that NAD stands for. Equipped with NAD’s ATOLogic circuit, which includes both a 12V-trigger system and signal-sensing power-on option, this extra level of flexibility makes it easy to integrate the C 275BEE into any control system. The C 275BEE also benefits from NAD’s PowerDrive™ circuit topology, which allows the C 275BEE to deliver maximum performance under various circumstances. Delivering a well-rounded, mesmerizing performance, the C 275BEE will let you hear your music the way it was meant to be heard.
