The MD-801RmkII could v ery well be the most advanced MiniDisc recorder ever, giving y ou the confidence that y oull be ready for anything.
Advanced Live Theater - Broadcast Applications - Show Control
In live applications, right the first time.  The MD-801RmkII tak es advantage of the tr ack names available in the MiniDisc format, since T rain Station lends abit more information about the tr ack than Track 37.  A uto Cue willsearch for the first audio in the tr ack, so you can eliminate lag timebetween the time y ou press PLAY and the time y ou hear it.  Auto Ready will stop at the next tr ack ID, preventing the pla yer from rolling right into the next tr ack accidentally .  For liv e applications where a sound cue disk can is assembled in show order order , the Auto Cue function will park at the start of the next cue ready for pla yback.  Broadcast standard fader start function is available in the par allel I/O, as are other remotes and tallies.
The MD-801RmkII RCA outputs to be used as a separ ate cue output.  A set of monitor speakers could be connected to the cue output so the audio can bechecked without pla ying through the normal outputs.
The MD-801RmkII control systems, and offers one of the most robust tr ansports in the business.  When the stakes are high, count on the MD-801RmkII. 
Recording Studio
MiniDischi-fi recorders, as well as pla yers for the car .  MiniDisc is a wonderful format for creating reference mix es for the ride home from the studio .  Plus, with instant start offered with the BU-801 RAM buffer , the MD-801becomes a powerful tool in assembly editing or sound cue drops.
