not recommend us ing the “Pr eS tr i ping” function, which formats at 4X speed.

Number of reels on a t ape
It is best to have one tape per reel , as this makes replacing r eels much easier.
However tape cos ts are hi gh. If more than one r eel per tape is recorded, then it is
recommended that continuous timecode i s recorded thr oughout the tape.
Synchronisation errors will then be mi nimi s ed. T he box must be cl ear l y labelled wi th
start and end ti mes . T here mus t be an absolute mi nimum of 1 minute between reel s .
Five mi nutes is recommended.

Punch-ins
If drop-ins or punch-ins are necessary, make s ur e the cr ossfade ti me on the machine i s
set to minimum. This is also another good r eas on for pre-formatting.
