Pre-Record Buffer; Media Select; Failure During Recording - Sound Devices 788T User Manual And Technical Information

If no tracks are armed to record, the 788T will not enter Record Mode. Make certain that at least one
record track is armed for recording.
While recording, the POWER, FAST FORWARD, REWIND, PLAY and TONE keys are disabled. See
Panel Lock to engage Panel Lock during recording. Stop recording by pressing and holding the STOP
key. The STOP key must be held for 150 msec or greater to end recording. Although you can enter
the Setup Menu during recording, menu items that affect recording are lined out in the menu list.
During recording, subsequent presses of the REC key can perform one of three Setup-Menu-selected
actions:
• no action,
• new cue - cue markers are set within the fi le being written,
• new fi le - a new fi le is started with each press of the REC key, the take counter increases by one.

Pre-Record Buffer

To prevent missing record cues or up-cutting takes, the 788T has a pre-record (or pre-roll) buffer.
When active, pre-record begins recording at a set number of seconds preceding the REC key be-
ing pressed. When recording higher sampling rates (48048 +) pre-roll is limited to fi ve seconds and
below.
Record buffering is disabled when the time code mode is set to Record Run, External Time Code
Auto Record, and External Time Code Continuous Auto Record. This prevents possible overlapping
time code numbers between adjacent fi les.

Media Select

The 788T can record up to 12 tracks to all three available media (internal hard drive, CompactFlash,
and external hard drives) simultaneously at sampling rates of 48048 and below. Higher Sampling
rates are limited to eight tracks to two media only. When recording higher track counts and higher
sampling rates, Sound Devices recommends using hard drives and high speed UDMA Compact-
Flash cards.

Failure During Recording

In the event of a storage media failure, the specifi c error will be indicated on the LCD and warning
bells in the headphone monitor. Possible causes of media failure include, a hard drive in severe mo-
tion which results in recording errors, a CompactFlash card fi lling up while recording, or an external
DVD-RAM that can't keep up with the chosen data rate, track count, or fi le type. If more than one
drive is selected for recording, the remaining drives will continue recording without failure. If a me-
dia continues to be displayed as slow after the warning prompt has been cleared, press the Stop key
to clear the Slow status.
