Il DV-RA1000HD è la versione più avanzata del registratore master DV-RA1000, con l’aggiunta di un HD interno e con nuove e più potenti funzioni di registrazione. Registra audio ad alta definizione, fino a 192 kHz/24 bit, su DVD+RW o DVD-RW o HD e può creare CD audio standard (16 bit/44.1 kHz) su dischi CD-R e CD-RW. Supporta inoltre il formato DSD, che è il file di base per la creazione di Super Audio CD (SACD). Con il formato DSD l’audio è registrato direttamente come segnale digitale ad alta risoluzione, non compresso, per riprodurre la forma d’onda analogica con qualità eccezionale.

Le funzioni di copia del DV-RA1000HD permettono all’utente di duplicare supporti ottici o copiare files audio da CD/DVD±RW su Hard Disk o viceversa. Per esigenze di archiviazione i dati audio possono essere scritti su supporti DVD-R e DVD+R. Il formato UDF 1.5 per DVD assicura la compatibilità con i lettori DVD dei computers.

Analogamente al DV-RA1000 il DV-RA1000HD è dotato di ingressi e uscite professionali inclusi AES/EBU, SDIF-3, RS-232C, USB 2.0, un connettore PS/2 per tastiera da computer per inserimenti di testo. I tasti funzione definibili dall’utente, il display LC retroilluminato, il controllo della tonalità (± 6%), l’uscita cuffie e molte altre funzioni per registrazione e riproduzione rendono il DV-RA1000HD un registratore versatile, di classe assoluta
