MECCANICA DI LETTURA CH PRECISION D1

 

Meccanica di trasporto CD/SACD. Meccanica Esoteric VMK-5 con VRDS NEO. Supporto di SACD multicanale e stereo oltre ai normali CD (CD-R/RW). 4 uscite digitali: 1 proprietaria CH Link che gli permette di collegarsi al convertitore C1, 1 AES/EBU, 1 S/PDIF e 1 Toslink. Opzionali sono la scheda di uscita digitale Digital_OUT da aggiungere a quella già fornita per ottenere un player audio multi-canale; la 2 canali analogica Analog_OUT, anch’essa installabile in un massimo di 3 per ottenere un player multi-canale; una scheda mono analogica top-class Analog_OUT_M (ce ne vogliono ovviamente due), e la clock sync board Sinc_I/O, per ricevere il sync dal C1 o da un generatore esterno (per esempio Esoteric G0RB). Oscillatori VCXO a bassissimo jitter. Manopola coassiale per la configurazione e regolazione. Display a colori RGB Amoled con risoluzione 480×272 pixels. Ingresso USB per aggiornamenti software. Controllo remoto tramite presa Ethernet. Connettore per stadio di alimentazione esterna X1. Telecomando.


Altre caratteristicheOptical Reading
