The NAC 332 preamplifier is the digitally controlled, pure analogue centre of your system. Each and every audio stage is meticulously designed using discrete transistors, building on 50 years of experience in manufacturing high-performance audio systems. It features a precision fixed resistor volume control and a class-A headphone amplifier, with XLR and RCA outputs.


Map any input button to any of the 8 input sockets, such as balanced XLR, DIN and RCA, allowing simple connection to any audio source. The NAC 332 has a powered DIN socket for connection with the NVC TT phono stage. The front panel has a ¼ inch headphone socket. Behind the socket is a 1.5W state-of-the-art headphone amplifier. On the rear panel, twin outputs of XLR and RCA allow connection to a variety of power amplifiers, or the ability to bi-amp.

Bi-directional wireless inter-product communication is used to connect the NAC 332 to the NSS 333 streamer, making them as easy to use as a single-box system. Optical control synchronises seamlessly with New Classic power amplifiers, such as the NAP 350.

Simplicity is the key. Buttons on the front panel allow quick access to inputs, volume, standby mode and mute. The bi-directional ZigBee remote allows complete control even without direct visibility of the product. The NAC 332 automatically detects no music and after 20 minutes will put the system into 0.5W stand-by mode.
