Ofera conexiune USB-A, doua intrari digitale - optic si coaxial - si este comepatibil cu Spotify Connect.

Bespoke Hi-Fi components taken from Denon’s high-end "NE series"

We have employed a number of audio electrolytic capacitors, resistors, film capacitors that are also used in the "NE series", a new generation of Denon's renowned Hi-Fi components. These optimum parts were selected by our lead sound engineer only after repeated auditions. To further refine sound quality, we introduced custom parts developed in collaboration with electrolytic capacitors parts manufacturers.

Amplificare integral digitala, cu sunet clar si puternic

Circuitul de amplificare foloseste tehnologie DDFA®. Etajul de iesire are la baza un circuit cu tranzitoare discrete ce asigura un nivel ridicat al raportului semnal/zgomot si atenueaza foarte bine distorsiunile, in comparatie cu o amplificare obisnuita in calasa D. Aceasta schema de amplificare ofera o calitate superioara a sunetului, la o putere maxima de 70W in 4 ohm. Iesirile pentru boxe sunt de inalta calitate si permit conectarea cablului cu multiple variante de conectori.

 

New generation class D amplifier – DDFA

The DRA-100 uses new generation "DDFA® (Direct Digital Feedback Amplifier)" class D amplifier technology. This achieves dramatic sound quality improvement by utilizing a high-speed and extremely accurate digital feedback loop. Processing is performed completely digitally from input to final stage PWM modulation, with no sound quality degradation. The 70 watt output (4 Ω) is 40% higher than on the PMA-50. This is achieved by the addition of a gate driver that improves instantaneous current supply capability. Furthermore, in order to deliver Denon's delicate yet powerful sonic the company carried out rigourous sound tuning using a discrete circuit for the output stage and the power supply circuit. The result is a high fidelity sound with rich expressive power and excellent audio characteristics, such as high S/N and low distortion when compared to most conventional class D amps.

Redare audio Hi-Res DSD via network sau USB

DRA-100 este compatibil cu standardul DLNA 1.5, astfel poti asculta, conectat in retea, muzica din computer sau de pe un HDD extern. Suporta formate audio MP3, AAC, WMA si chiar fisiere Hi-Resolution WAV, FLAC, AIFF la 192kHz/24bit, DSD la 2.8 si 5.6 MHz (DSD este un codec digital audio pentru SACD). Iesirea USB, amplasata pe panoul frontal, poate reda aceleasi formate cu suport special pentru conectarea echipamentelor portabile Apple.


Multiple intrari audio digital si stereo analog

Pe langa intrarea USB-A, DRA-100 ofera si 2 intrari audio digital optic, 1 intrare audio digital coaxial, precum si doua intrari audio anlalog pentru conectarea surselor clasice stereo.

Fully digital processing

Since DDFA is a digital input type Class D amplifier, when playing back a digital source, interpolation processing by "Advanced AL32 PP" technology, volume adjustment, amplification, and feedback management is all undertaken in the digital domain. This makes it possible to eliminate the influence of external noise which can become a problem with analogue amplifiers. The end result is a broad soundstage with excellent transparency and resolution.
* Advanced AL32 Processing Plus is compatible with PCM signals only

Procesare performanta audio digital AL32

DRA-100 are un procesor audio de inalta performanta capabil sa proceseze cele mai noi codecuri audio pe 16-bit, 20-bit sau 24-bit. Inclus doar pe modelel Denon Premium, procesarea AL32 realizeaza prin aplicarea de filtre digitale upconversie la 32-bit. Astfel sunetul capata o dinamica mai mare pe un spectru mai larg de frecvente si o imbunatatire evidenta la nivele joase.

 
 

Master Clock

Advanced AL32 Adopt master clock design that operates FPGA and USB digital audio interface with master clock supplied from ultra-low jitter clock placed close to FPGA that performs processing such as Processing Plus. By precisely synchronizing each digital circuit with high quality master clock, high quality reproduction with reduced jitter is realized. In addition, it switches the two systems of clocks of the 44.1 kHz system and the 48 kHz system according to the sampling rate of the input signal, and supplies the clock of the optimum frequency. By eliminating jitter due to non-integral multiplication, we suppress waveform fluctuation in the time axis direction and perform ideal signal processing.

Conectare wireless via Bluetooth Conectare prin NFC

Conectat prin Bluetooth poti asculta, cu DRA-100, muzica direct de pe telefon sau tableta. Conectare este extrem de simpla si se poate realiza chiar si mai usor prin NFC (Near Field Communication). Activezi functia NFC pe device-ul mobil si il apropii de DRA-100, in zona unde este indicata litera N pe panoul frontal. Pairing-ul este realizat instant.

Bluetooth si Wi-Fi integrat

Denon DRA-100 este prevazut cu Wi-Fi si Bluetooth. Te conectezi la retea prin Wi-Fi (sau poti alege conctare prin cablu LAN) si asculti muzica online. Poti alege serviciul preplatit Spotify Connect sau miile de posturi Internet Radio, stucturate perfect pe genuri muzicale. Este compatibil AirPlay si asculti extrem de simplu fisierele audio redate de pe dispozitivele iOS - iPod touch, iPhone si iPad. DLNA 1.5 asigura conectarea la PC sau Mac. Aplicatia Denon remote App vine in ajutor si poti controla, la fel de simplu, tot ceea ce asculti direct de pe telefon sau tableta. Fie ca este sistem Apple sau Android.

Constructie compacta cu display OLED

DRA100 are o constructie compacta cu finisaje elegante. Se evidentiaza liniile argintiu lucuios pe suprafata aluminu mat. Displayul OLED asigura o afisare clara si detaliata a informatiilor necesare - sursa conectata, frecventa de sampling si tipul de format audio digital redat.




Telecomanda ergonomica

Telecomanda inclusa in pachet are un design ergonomic si navigare facila. Curosn, selector de surse, control volum, meniu setari, buton pentru Bluetooth si dimmer pentru iluminare afisaj.

 

Iesire de casti de inalta calitate cu posibilitate de selectare a impedantei pentru casti

DRA-100 vine cu un circuit separat de amplificare pentru casti. Fidelitate audio de top, asigurata prin tranzistori cu distorsiuni extrem de mici pe intreaga banda de frecvente. Si, pentru a satisface cat mai multi din utilizatorii de casti, permite setarea impedantei in functie de tipul de casca utilizat, pentru o obtine un matching perfect. Intrarea de casti este compatibila si cu tipul de conector jack 6.3 mm, folosit la castile premium si cele de studio.
