NAD C165BEE Stereo Preamplifier

NAD C165BEE

Distinguished amongst analogue preamplifiers, the C 165BEE is built to be the heart of any advanced home audio system. Starting with six line level inputs, including MC/MM phono input, the C 165BEE is incredibly flexible. Featuring a superbly designed tone control circuit, the C 165BEE is an exceptional example of how to implement high-fidelity tone controls by affecting only the frequency extremes and leaving the critical midrange untouched, while also offering a bypass option. With a 12V-trigger output and IR inputs and outputs on the rear panel, the C 165BEE is ready to integrate with CI control systems. With outstanding build quality and true engineering sophistication, the NAD C 165BEE is the preamp you’ve been waiting for.
