Listening Optimization
The linear and neutral sonic bias of the A200 makes it suitable for a wide range of speakers and sources. The EQ presets and loudness (bass enhancement) selections tuned via a high-speed DSP allows further sound tailoring to the system and music.
Technical Highlights
NuPrime Omnia A200 accomplishes its seemingly incompatible objectives of being the most powerful, compact, and yet low noise streaming amplifier through the following innovative design features:
- NuPrime Dynamic Low Noise Switching Power Supply (DLN PS) Design:
- The power supply has a built-in dual-core dual-system that reacts to the output power demand of the power amplifier. Three levels of control utilizing a small transformer during low power, followed by a large transformer when power demand increases, and finally two power supplies working together to maximize power delivery.
- The switching frequencies of the power supply are automatically adjusted between 60kHz and 180kHz, according to the output power demand of the power amplifier.
- The A200 Class-D amplifier achieved low noise through a secondary feedback signal that resulted in clear and detailed sound characteristics.
- The A200 speaker output incorporates a two-stage output filter to reduce high-frequency frizz for more transparent sound with less listening fatigue.
In addition, the A200 utilizes ultra-high thermal conductivity silicon oil and high purity copper blocks for fast heat conduction.
The Omnia A200 uses a compact and powerful Class D amplifier. The maximum output power can reach 250W stereo output (@4ohm speaker) and uses integrated feedback design and error correction, achieving extremely low noise and distortion. Unique Dynamic Low Noise Switching Power Supply (DLN PS) provides excellent system-level audio performance.

What is Linkplay ?
Linkplay provides the module that manages the streaming protocol, communications between devices, and data routing in re-streaming and multi-room configurations. Products that use the LinkPlay module can have significant feature and performance differences as LinkPlay is a communication level module. In general, products that are LinkPlay compatible can be used together as a system. A partial list of LinkPlay compatible products are listed here: https://www.linkplay.com/products-powered-by-linkplay
Nuprime customers can mix and match products to maximize performance (with only Nuprime components) or convenience (Nuprime streamer with compatible speakers).

Explicatii in ceea ce priveste rodajul echipamentelor, cat si al cablurilor, asezarea optima a echipamentelor in camera de auditie, importanta acusticii camerei si nu in ultimul rand sistemul de alimentare a intregului echipament:
PENTRU BOXE:
- Pentru performante optime este necesara pozitionarea boxelor la o distanta de minim 30-40cm de peretele din spate pentru boxele cu bass-reflex in spate, pentru cele cu bass-reflex in fata, recomandam pozitionarea la o distanta de 10-20cm fata de peretele din spate, dar totodata la o distanta de cel putin 50cm fata de peretii laterali. Tineti cont de faptul ca orice piesa de mobilier din incapere, joaca rol de absorbtie fonica, dar si de difuzie fonica daca acestea din urma sunt din materiale ceramica sau oglinzi, geamuri sau alt material reflectorizant. In acest sens, gasiti pe blogul nostru, multiple articole care va pot ajuta
- Boxele vor ajunge sa functioneze in parametrii recomandati de producator, dupa minim 50 de ore (ideal 100 ore) de functionare la volum mediu. In aceasta perioada de timp, de “rodaj a boxelor”, sunetul va fi la inceput mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce boxele vor functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate. Exista boxe care necesita un „rodaj” mai amplu de minim 300 de ore mai ales in cazul celor care au difuzoare de kevlar, carbon sau alte materiale de acest tip. Boxele care se „rodeaza” cel mai repede sunt cele care au difuzoare de celuloza.

PENTRU AMPLIFICATOARE, DAC-URI, PREAMPLIFICATOARE, RECEIVER STEREO & HOME CINEMA, SURSE DIGITALE AUDIO-VIDEO:
- Pentru performante optime este necesar „rodarea” echipamentului, In functie de complexitatea componentelor din aparatul dumneavoastra acesta poate dura intre 30-200 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca acesta este alimentat corect conform manualului de utilizare la 220-230 Volti si trece semnal audio sau video dupa caz prin el.
- Echipamentul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce echipamentul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
- In ceea ce priveste echipamentul video precum videoproiector, TV, media player, blueray player, necesita un "rodaj" de cel putin 50 de ore. Lipsa acestuia nu va poate oferi maxim de performanta. "Rodajul" se efectueaza prin simpla utilizare a acestuia, intr-un mod conform specificatiilor mentionate de producator.
PENTRU CABLURI:
- Pentru performante optime este necesara „rodarea” cablurilor, In functie de complexitatea conductorului folosit, cat si geometriei acestuia, „rodajul” poate dura intre 30-100 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca va trece semnal audio sau video dupa caz prin el.
- Cablul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, pe masura ce cablul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.

Tratamentul Acustic si Izolarea Fonica
Pentru un sistem echilibrat, trebuie tinut cont pe langa asezarea corecta a boxelor in incapere, al echipamentelor, sistemul de alimentare al acestora, tinand cont de instalatia electrica a locatiei.

NUPRiME Audio
Dupamulti ani de OEM (Original Equipment Manufacturer) in spate, Jason Lim,co-fondatorul NuForce, a decis, in 2014, sa cumpere actiunile diviziei de HighEnd a companiei si sa porneasca o noua afacere. Beneficiind de excelentatehnologie mostenita de la NuForce si de o echipa noua de ingineri foartetalentati si dedicati in intregime pasiunii pentru echipamentele audio, NUPRiME a avut o ascensiune fulminanta.
Pentru prima data in istoria industriei audioHigh End, un brand a primit, in acelasi an, patru premii Product of the Year,din partea prestigioaselor publicatii The Absolute Sound si SoundStage!.
Unadintre explicatiile pentru succesul atins este integrarea pe verticala. Foarteputine marci de renume din domeniu au propriile fabrici si-si permit sa nuexternalizeze productia catre un OEM. NUPRiME este una dintre acestea, astfelca nu doar controlul calitatii este perfect, dar si costurile pot fi mentinutela un nivel foarte accesibil. Mai mult, intreaga gama de produse NUPRiME (amplificatoare, servere media, DAC-uri, casti, preamplificatoare, receiverhome theater sau amplificatoare de casti) beneficiaza de cateva integraritehnologice unice, ceea ce le face printre cele mai bune la raportulcalitate/pret din intreaga industrie.
Pricipiulde baza al companiei este sa stabileasca pretul final al unui produs exclusivpe criteriul costurilor de productie, nu pe calitatea sunetului sau pegreutatea obiectului.
Una dintre cele mai importante inovatii tehnologice marca NUPRiME este implementarea unui chip logic numit FPGA, care inlocuieste rezistoarelefoarte scumpe din arhitectura unui preamplificator/DAC de top. Astfel, NUPRiME se afla in postura unui gigant din lumea audio care-si permite sa-si vandaminunile cu preturi pe care si le poate permite orice pasionat.
