Electronic editing. This type of editing requires the use of two tape recorders/reproducers. Refer
to Lesson 3 for functions of a reel-to-reel recorder/reproducer. Use the procedure below to make
electronic edits.
a. Make -a copy of the master audio tape to be edited.
b. Locate edit material on the copy tape.
(1) Find edit start point, mark with grease pencil.
(2) Time audio to be edited with a stop watch or clock watch with second hand.
(3) Find edit end point.
(4) Recue tape to edit start point.
c. Locate insert material on tape with editing material.
(1) Find insert start point.
(2) Time audio to be edited.
(3) Find edit end point.
(4) Reconcile times so that time of edit and time of insert are equal.
(5) Recue tape to insert start point.
d. Record silence to edit space.
e. Simultaneously play back insert while recording is in edit space.
f. Play back edited material to check edit and time.
6.
Duplication. One way of duplicating tape is to use at least two tape recorders. One plays the
original, and the other plays the copy. The basic hookup is from output of playback deck to the input of
the recording deck. To interconnect two or more tape machines, it is necessary to impedance match the
systems. If impedance matching is not done, there will be a loss of frequency response (a db loss) and
possibly unwanted distortion.
a. Duplicating procedures are relatively simple. First interconnect the equipment observing
impedances, then set the playback level of the original and the record level for the duplicates. After
making sure the decks are in the correct mode, start the tape machines. Start the playback deck by
pressing the play button and start the duplicating decks with play and record buttons.
