NAD M33 Amplificador Integrado com DAC e Leitor de Streaming BluOS

Na sua forma mais simples, o DAC / amplificador M33 BluOS ™ ativado é um amplificador de streaming de desempenho ultra-alto com som audiófilo excelente. Como componente habilitado para BluOS, o M33 pode ser combinado com outros players em um ecossistema BluOS de tocadores de música em rede sem fio em toda a casa, para um excelente sistema de áudio para toda a casa. Com o emprego da nova tecnologia de amplificador digital híbrido Purifi Eigentakt ™, o M33 segue a longa tradição da NAD na identificação e desenvolvimento de tecnologia de amplificação de ponta. Com um mínimo de 200 W por canal na torneira, o resultado é um desempenho realista, exemplificado por distorção e ruído ultra-baixos.

The Bar has been Raised with the Masters M33 BluOS Streaming DAC Amplifier

Our Flagship Model Builds On Remarkable Success with Advanced Features, Cutting-Edge Technology and High Power

Part of a growing ecosystem of compatible products, BluOS tightly integrates hardware and software for an exceptional user experience. The only true wireless High-Resolution multi-room system available today, BluOS supports the new standard for High Res streaming, Master Quality Authenticated (MQA). BluOS also supports over 20 free and paid subscription services as well as supporting locally stored music libraries. With BluOS, the M33 retains all the audiophile features and further adds a range of facilities that will expand its capabilities yet simplifies ease-of-use at the same time. Operable with the BluOS app, the supplied remote control or through hands-free control with any Amazon Alexa or Google Assistant device, the M33’s front panel never needs to be touched.

DIRAC Live Room Correction On Board

Experts agree that room acoustics are the weakest link in most sound systems with room reflections deteriorating tonal balance and dynamics. Dirac, one of the most highly regarded Room Correction systems available, not only adjusts for frequency response, but unlike other room correction systems, it also optimises the impulse response. By optimizing the speaker/room interface, music sounds more natural and lifelike. Supplied with the M33 is a precision microphone to measure the room at and around the listening position so your system can be precisely calibrated for optimum performance. Even the most sophisticated loudspeakers can be markedly improved using Dirac calibration. Each of the 5 Dirac memory slots can store a unique room measurement or different frequency target curves to suit a particular musical taste or genre. The M33 also supports Dirac’s advanced ‘Bass Control’* feature with two independent subwoofer outputs.

Flexibility Meets Long-Term Value

In its standard form, the M33 is very complete with a wide range of in/outputs, BluOS, Dirac, HDMI and more already fully integrated. It will meet the requirements of the most demanding users. To minimize the risk of future obsolescence, the M33 comes with two MDC (Modular Design Construction) slots that allow for further expansion. NAD introduced the MDC platform well over a decade ago and allowed updating products with new technologies which didn’t even exist at time of introduction

Connection and Wireless Flexibility

Whether looking to connect digital or analogue sources, the M33 comes well equipped to accommodate for all of these: 6 digital inputs and 3 analogue inputs, including MM phono. Around back, the rear panel hosts two sets of speaker outputs capable of bi-wiring and a stereo Subwoofer Output with a fully configurable Digital Crossover. Airplay 2 and Bluetooth AptX-HD allow for local wireless streaming from a phone or tablet.

*Some features will be available via a future software update

Phono and Headphones Are Not Forgotten

The M33 has a high-quality MM Phono Input that rivals specialized outboard units. Accurate RIAA equalization, a clever phase cancelling infrasonic filter, and a huge overload margin combine to bring out the best in LPs. Furthermore, headphone enthusiasts will delight at the sound of the discrete headphone amplifier, which is able to drive even planar and high impedance studio phones. With high voltage and low output impedance, headphones will sound their best. For those who wish to enjoy their headphones but not be tethered to a cable, the integrated Bluetooth AptX-HD module makes it simple to possible to enjoy wireless headphones as well.

Attractive Design With Outstanding Ergonomics

The all alloy casework is elegant yet practical. The single control knob for volume is supplemented by a colour TFT touchscreen display. Rigid panels with magnetic iso-point feet provide a solid foundation for the multi-layer circuit boards and intricate internal construction. The M33 employs a completely modern and fresh take on the traditional stereo amplifier, with features and performance from the future.

Smart Home Integration Made Easy

BluOS provides hands-free control with full integration of any Amazon Alexa or Google Assistant device. Through Airplay 2, control is also possible with Siri. Considerable effort has been spent to make the M33 fully compatible with all the leading smart home systems from leading companies like Apple, Crestron, Control4, Lutron, KNX and many others. This means that along with lighting, shades, HVAC, and security, the integrator or user can seamlessly control the BluOS multi-room music system from a common interface. All integrations are certified for reliable operation. The custom BluOS Apps for iOS and Android tablets and phones, as well as desktop control from Windows and Apple OS are available free-of-charge and are updated regularly.

NAD M33 test review by Darko Audio



Em 1972, a NAD (originalmente um acrónimo para “New Acoustic Dimension”, em Português, Nova Dimensão Acústica) decidiu-se a criar um novo tipo de empresa áudio. Inicialmente era um grupo de veteranos da indústria áudio: fabricantes, retalhistas, distribuidores, e – acima de tudo – audiófilos. Movidos pela paixão de um grande som e pelo desejo de passar por cima das campanhas publicitárias e de uma elaboração exagerada dos aparelhos que se tornou generalizada na indústria do áudio, queriam dar às pessoas o que elas realmente queriam e não o que a indústria lhes queria vender. A mesma, onde a NAD entrou em 1972 tinha sido criada pelos próprios consumidores ainda durante os anos 50. Quem quisesse algo mais do que um rádio de vendas em massa, procurava equipamento de som e juntava as complexas peças da melhor forma que conseguia. Algumas pessoas iniciavam um negócio para fabricar aquilo que não conseguiam encontrar. Na altura em que se deu a “Revolução do Rock” nos anos 60, o interesse num bom equipamento tornou-se tão óbvio que os maiores jogadores da indústria eletrónica iniciaram uma prospeção na indústria que os pioneiros do áudio haviam criado. Trouxeram muita despesa, complexidade, e uma hipérbole com eles. O marketing do equipamento áudio fez tanto barulho que a qualidade se tornou cada vez mais difícil de encontrar e apreciar. A Nad queria chegar novamente ao cerne da questão — a realidade por trás dos botões e dos painéis frontais incrivelmente dispendiosos. E ainda hoje o faz com cada peça de equipamento que desenha. O verdadeiro propósito de todo o equipamento de áudio é obviamente o prazer — de um som natural e envolvente, de música e filmes. E as três qualidades que a NAD pensa serem fulcrais para a criação de um grande produto são o desempenho, valor, e simplicidade.
