Naim NAC 332 Preamplifier - Naim Performance and versatility combined; the NAC 332 can be easily configured to suit your audio world. This preamplifier is the digitally controlled, analogue centre of your system. Every audio stage is meticulously designed using discrete transistors. The NAC 332 also features a precision fixed resistor volume control and a class-A headphone amplifier, with XLR and RCA outputs. Simple connection The NAC 332 can 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. It also features a powered DIN socket for connection with the NVC TT phono stage. The front panel has a ¼ inch headphone socket with a 1.5W state-of-the-art headphone amplifier behind. On the rear panel, twin outputs of XLR and RCA allow connection to a variety of power amplifiers. The finest components The innovative electronic circuits give the NAC 332 an excellent audio performance. The best components, such as through-hole resistors used in the volume control, have been selected. The architecture of the Statement volume control is carried over to the NAC 332, using reed relays to switch between the volume resistors. This ensures premium sound quality, the ability to have adjustable input sensitivity and the capability to set a maximum volume level. Timeless and contemporary Nothing detracts from the NAC 332’s performance. All our creations have a simple design, with outstanding sound quality at the forefront of our products. The NAC 332 combines a sleek design, premium materials, adjustable logo brightness, and engineered touch points, such as the precision raced bearing volume control, to give you an unrivalled listening experience. Inter product communication As easy to use as a single-box system, with bi-directional wireless inter-product communication, the NAC 332 connects seamlessly to the NSS 333 streamer. Optical control also synchronises with the New Classic power amplifiers, such as the NAP 350. Why aluminium? Not only did we give our creations a sleek and uniform design, but our founder, Julian Vereker, understood the many benefits of aluminium. He recognized why it was the most effective material for encasing Naim electronic components. He knew that delicate audio components are susceptible to the effects of magnetic fields, unstable temperatures and unwanted vibrations. What to expect in the box: NAC 332 Preamplifier Product Details: Key Points Statement volume control architecture using reed relays. Premium sound quality of fixed resistor volume control, providing precise channel balance. Uses super smooth fly-by-wire optical encoder with precision ball raced bearing. Reed relay input switching. Class A discrete balanced input circuits (via two single ended class A buffer, one for hot and one for cold, feeding a discrete class A op-amp). Single ended discrete transistor class A input buffers and filter circuits, using hand soldered polystyrene capacitors (Custom ultra-low dielectric absorption filter capacitors). Configurable inputs: Input sensitivity pre-set, AV bypass mode and mapping of input socket to button. ZigBee RF bi-directional remote control, line of sight not needed, volume changes reflected on the remote. Optical in and out 3.5mm inter-product communications for synchronised standby and lighting with compatible power amplifiers PSU upgrade with NPX 300 via two Burndy cables (one digital and one analogue). 0.5W standby power Using two internal power supplies; one is a high quality audiophile linear type, based on a large toroidal transformer. The other is a highly efficient SMPSU for 0.5W power consumption in standby during standby mode. Galvanic isolation of control and audio circuits.
