SPECIFICATIONS
BR-1200CD: Digital Recording Studio
Tracks
Track: 12
V-Track: 192 (16 V-Tracks per each Track)
Up to 2 tracks can be recorded simultaneously, and up to 12 tracks can be
played back simultaneously.
Maximum Useful Capacity/Recording Time
Internal Hard Disk:
40 G bytes (recording time; 120 hours) (conversion in one track)
*
The recording time is approximate. Times may be slightly shorter depending on
the number of songs and size of imported loop phrase that were created.
*
The recording time is the total for all the tracks that are used. If each of the
twelve tracks contain an equal amount of data, the length of the resulting song
will be approximately 1/12 of the above.
