Rockna wavelight pre/dac

4499.00

DAC priekšpastiprinātājs ir izgatavots pēc 25 bitu R2R shēmas, ko kontrolē FPGA Xilinx Spartan 7. Pilnīgi analoga skaļuma kontrole.
Aprīkots ar I2S (LVDS), Toslink, Coax, AES / EBU un USB-B interfeisiem, analogās RCA ieejas, XLR un RCA izejas.
Tiek apstrādāti bitu pārraides ātrumi 32/384 PCM un DSD512. Uzstādīti divi atsevišķi toroidālie jaudas transformatori analogām un digitālām daļām – ar filtra kondensatora jaudu 100 milifarādi.
