EDITING AND SPLICING
FOR FAST EDITING
Cueing and general edi ting ca n be done at high sp ee d by shuttling the
t ape bac k and forth betwee n the " RE WIND " and " FAST FORWARD"
modes . E xa ct pl aces to be ed i te d ca n be loca te d by h an d ad justment of
the reels while monitoring with the he ad phones. Corrections can sometimes
be made by eras ing and re- record ing, but are m or e often made by cutting
and splicing the tape .
FOR CORRECT SPLICING
1 Cut the two end s of tape as show n.
2 Butt ends togethe r on a flat su rface, u ncoate d (" sh iny") side up .
3 Splice the joint with splicing t ap e reco mm e nde d by the recording tape
manufactur e r.
4 Ca refully trim the sp li ced area to si ze .
CAUTION
Be sure to use splicing implements that are not magnetized.
TO ERASE AN ENTIRE TAPE
To erase a previously recor ded tape without recording a n ew program an
it , turn both MIC RO PHONE RECORD LEVEL and LIN E RECORD L EVEL
controls to "Z ER O ,"' and run the tape through in the " RE CO RD" mo de .
It is not necessary , however , to erase a tape in this manner prior to ma king
a new recor ding on a previously recorded tape , since full erasure of any
previous recording an the t ape is automatically done concurrently with
the recording process whenever the machine is in the RECORD mode of
operat ion.
