Extending the Recording Time 147

D24—Owner’s Manual
Extending the Recording Time

The total continuous recording time can be extended by using two D24s and the Serial

Point function. The master D24 records the first half of the material, and the slave D24,

which kicks in at the specified serial point, records the second half of the material.

In the following example, two D24s are used in conjunction with a digital mixing con-

sole for extended recording. The Slot Output Select function is set on the digital mixing

console so that both D24s receive the same bus signals. D24-A track outputs feed tape

returns 1–8, while those of D24-B feed tape returns 9–16.

D24-A is the wordclock and timecode master, while D24-B and the digital mixing con-

sole are wordclock and timecode slaves. Wordclock and timecode signals are transmit-

ted from D24-A to D24-B via the 15-pin sync cable.

A single 640 MB Overwrite-type MO disk offers 15 minutes of 8-track, 16-bit, 44.1 kHz

recording, so two D24s offer a combined 8-track recording time of 30 minutes. The

serial point time is set to zero (00:00:00.00) on D24-A, and 14 minutes, 30 seconds

(00:14:30.00) on D24-B, as shown below. The Chase function is turned on on D24-B,

which automatically chases and synchronizes to the master’s timecode at the specified

serial point.

When recording or playback is started on D24-A, the D24 -B waits until the specified

serial point, at which it chases and synchronizes to D24-A’s timecode and then starts

recording or playback. D24-A continues for another 30 seconds and then stops. This 30

second overlap can be used to crossfade between the slave and master D24s during play-

back.
