NAD C 3050, stereo stiprintuvas su DAC ir Bluetooth

NAD C 3050 - 1970 metais gaminto NAD 3030 įtakoje sukurtas retro stiliaus, šiuolaikiškas modulinis stereo stiprintuvas su integruotu aukštos rezoliucijos Texas Instruments PCM5242 DAC'u ir galimybe įmontuoti papildomą NAD MDC2 BluOS-D plačių galimybių tinklo modulį (pekamas atskirai - 499€).

C 3050 taip pat turi integruotą Dirac Live Room Correction, kuri, kalibruoto mikrofono pagalba, atlieka kambario akustikos įvertinimą ir atitinkamų stiprintuvo parametrų derinimą dažnių diapazone iki 500Hz.

Stiprintuvas turi galingą stereo stiprintuvą, integruotą ausinių stiprintuvą, Phono MM įėjimą, dvipusį aptX HD Bluetooth ryšį, HDMI e-ARC jungtį.

NAD'e panaudotas UcD stiprintuvo schemos dizainas yra gerai žinomas dėl labai mažų triukšmų ir iškraipymų visoje garso dažnių juostoje, nepriklausomai nuo kolonėlių apkrovos.

Stiprintuvą galima integruoti į namų automatikos sistemas: Control4, Crestron, Elan, RTI ir kitas.
