Introducing the NAD C 368.

Getting it Right

We never overlook the most crucial of requirements. From low noise circuits to precise volume control action, to accurate channel balance and proper input and output impedance characteristics, we here at NAD do everything we can to get these things exactly right. We also include an MM Phono stage with precisely accurate RIAA equalization, high overload margins, extremely low noise, and an innovative circuit to suppress infrasonic noise that is present on all LPs – all without affecting bass response. Our line inputs can accommodate all kinds of analogue source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation. We include a separate headphone amplifier with low output impedance and very high output voltage capability – enough to drive even high impedance studio monitor headphones. Low impedance line outputs that can connect to subwoofers extend the versatility of this well thought out amplifier.

Forward Thinking

Modular Design Construction (MDC), allows you to customise your NAD amplifier with additional capabilities and features, now or in the future. The two available MDC slots can accommodate a variety of upgrade modules including 4K video capable HDMI switching, additional Digital Inputs, additional Analogue and Phono Inputs, and one of the most advanced Hi-Res Audio multi-room wireless systems available, the BluOS music management system developed by Bluesound. BluOS connects to your network and is controlled via smartphone, tablet or desktop to manage your music collection and connect you to a growing list of high-quality streaming music services.

Instant Connection

You can connect instantly to the C 368 with Bluetooth^® aptX^®, allowing you to stream music wirelessly from any Bluetooth-enabled device. Bluetooth can also be used to listen to other sources connected to the C 368 via wireless headphones. There is also a control app to control all functions of your C 368. Adding the optional BluOS Module provides access to your local area network via Wi-Fi or wired Ethernet connection and adds Hi-Res Audio streaming. The BluOS Module also makes the C 368 a single-zone streamer in a complete multi-room wireless music system that is fully compatible with BluOS Enabled music systems and wireless speakers.

Sophisticated Power

In the last few years, NAD has moved away from the old-fashioned linear power supplies and Class AB output stages that waste energy, and have instead developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has created some of the best performing amplifiers regardless of basic design principle. These new designs are very linear over a wide bandwidth and provide consistent performance into all speaker loads, providing a dramatic advance over previous models.

Furthermore, the power supply is capable of 80 watts continuously and over 120 watts instantaneously to allow for short-term musical transients. It can operate with any AC mains voltage from 100 to 240 volts and provides pure DC power to all the various stages of the C 368. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.

The C 368 uses a customized version of the proven Hypex UcD output stage. This allows for massive power with nearly unmeasurable distortion and noise in the audible range. Every detail of this design has been carefully planned and perfectly executed to produce every last drop of performance.

LEGEND L200

Legend Series Large Premium Bookshelf Speaker

• Drawing from more than 45 years’ experience in developing loudspeakers, the Legend Series defines the next generation of Polk.

PREMIUM 6.5” STANDMOUNT 

The L200 is the premium bookshelf speaker in the Legend series that demands to be heard. Feel the energy as you are transported to the front row of a live rock concert or to enjoy the intimacy of your favorite jazz trio. The Legend standmount speakers transform your listening space by revealing every detail from the delicate finger taps of a guitarist on the fretboard to the deep bass of an orchestra’s kettle drum and to the smooth tones of your favorite singer/songwriter. This big bookshelf speaker delivers the power without sacrificing detail and fidelity. The L200 is perfect for stereo listening or as a front stage in any home theater setup.

Polk’s goal since its founding has been to build great loudspeakers that virtually transforms the listener’s room into the scene of the recorded performance. To meet this challenge, Polk engineers and designers must constantly innovate and agonize over every detail. Nothing is left to chance and nothing unnecessary is ever added. The results are best-in-class loudspeakers that outperform their competition for half the price, earning numerous awards, patents, and most importantly Polk speaker owners that swear by the brand. Don’t take our word for it – go listen and you’ll believe. 

NEW HIGH RESOLUTION 

PINNACLE RING RADIATOR TWEETER

40 plus years of tweeter innovation, design and prototyping has led to the development of the new 1” high definition Pinnacle ring radiator tweeter. Developed by Polk Audio, it delivers ultra-clear, crisp highs without unwanted coloration or distortions. The Pinnacle tweeter features a finely tuned waveguide that dramatically improves the dispersion of high frequency energy ensuring a broad “sweet spot” and while the critically damped rear-chamber helps to defeat any unwanted resonances. Hi-Res certified, the Pinnacle Tweeter is designed for today’s two-channel music listening as well as multi-channel 3D audio found in music, movies, sports, and video games soundtracks.

NEW 6.5" TURBINE CONE

Polk developed the new Turbine cone specifically for the Legend series to ensure the natural reproduction of the mid-range, the frequencies our ears are so sensitive to. The Turbine cone combines Polk’s proprietary foam core and the molded Turbine geometry which dramatically increases stiffness and damping, without adding mass, resulting in a smooth, detailed mid-range and effortless bass – hear every detail.

BETTER BASS BY DESIGN

ENHANCED POWERPORT

Traditional bass ports make noise (chuff) and mask the low frequency bass notes you want to hear. The new enhanced Power Port® design smoothly transitions air flow from the speaker into your listening area for louder, cleaner bass while minimizing turbulence, distortion, and port noise. Polk refined their current Power Port technology specifically for the Legend series by fine-tuning the geometry of the port flare. Hear and feel the difference; Polk Enhanced Power Port® produces less port noise and more powerful clean bass than traditionally ported loudspeakers.

COMPLIMENTS YOUR HOME THEATER

Can be used for the front stage of any home theater, as well as side and rear surrounds. Legend Height Module (L900) are only compatible with floorstanding models.

ANTI-DIFFRACTION MAGNETIC GRILLE

Comes with a grille to cover the front baffle and a second grille for the top to cover the optional height module when installed. Computer modeled for a precision fit and to minimize sonic interference. The acoustically inert magnetic grilles offer a clean aesthetic without sacrificing sound.

LARGE DUAL 5-WAY BINDING POSTS

Perfect for easy setup, they ensure the most direct, efficient, and loss-less connection possible. Dual binding posts support both bi-wire and bi-amping.

HIGH-RESOLUTION CERTIFIED

Your sound is only as good as your source. For your investment in DSD, FLAC or a high-resolution streaming service, the Polk Legend L200 is Hi-Res certified so you can be confident favorite songs will be faithfully reproduced. Trust Polk Legend series to bring out all the detail and nuance of every track.
