RME ADI 2 FS visokoprecizni AD/DA konverter

Opis

Visokoprecizni 192kHz dvokanalni AD/DA konverter

ADI-2 FS je kompaktan i veoma fleksibilan dvokanalni napredni AD/DA konverter. Uređaj nudi AD/DA konverziju prve klase sa i na SPDIF, AES i ADAT konekcije sa sample rate do 192kHz. NJegova sposobnost da radi sa SPDIF, AES i ADAT formatima ga čini super kompatibilnim za razne situacije.

Analogni i digitalni ulazi i izlazi

Balansirani analogni ulazi i izlazi, monitoring preko Headphone izlaza za slušalice, SteadyClock FS za optimalnu konverziju, trostepena hardverska kontrola ulaznog i izlaznog nivoa i dodatni D-D i A-A režimi pretvaraju ADI-2 FS u univerzani alat konverzije. Njegova pro-klasa zvuka ga stavlja u ravan sa premium konverterima.

Dva balansirana XLR/TRS ulaza, digitalni optički ADAT i koaksijalni SPDIF

ADI-2 FS je opremljen sa dva servo-balansirana analogna linijska ulaza sa XLR/TRS kombo konektorima na kojima možete koristiti i balansirane i nebalansirane konekcije. Tu je podesivo headphone pretpojačalo za slušačlice na prednjoj ploči i ADAT kompatibilni optički SPDIF ulaz i izlaz, te koaksijalni SPDIF ulaz i izlaz (RCA, AES/EBU).

Analogni ulazi koriste napredna strujna kola razvijena za ADI-2 Pro verziju konvertera, pa zbog toga raspolažu sa izuzetno malim šumom i izobličenjem signala sa veoma širokim frekvencijskim opsegom. Tri različita nivoa za ulazni i izlazni signal obezbjeđuju perfektnu analognu kompatibilnost sa drugim uređajima.
