The Audio Cassette Duplicator is used to make one, two, or three simultaneous duplicate copies of standard audio cassettes. The ACC-4000 copies one or both sides, and copies in stereo.

Operation of the cassette duplicator:

1. Turn the duplicator on. The power switch is located on the back panel directly below the center of the unit. It is a rocker switch; depress the right half of the switch (as felt from the front of the unit) to turn the machine on.
2. Load the cassettes into the machine. Insert the ORIGINAL tape into the LOWER LEFT cassette chamber, the one with the red label marked "ORIG". Load the blank tape(s) into any of the remaining chambers, the ones with the black labels marked "COPY".
   
   CAUTION: Cassettes loaded into the "COPY" chambers WILL BE ERASED. The ACC 4000 Duplicator ignores the erase-protection notches in the back of the cassette. Be careful! DO NOT load your original cassette into the "COPY" chamber. Insert original cassettes into the LOWER LEFT "ORIG" chamber only!
   
   
3. Determine the type of duplication you wish to perform and set the control switches accordingly:
   • To copy one side of the cassette only, press the Side Select button until the green "A" indicator lights.
   • To copy both sides of the cassette, press the Side Select button until the green "AB" indicator lights.
   • Under normal circumstances, make certain that the green "Auto" indicator is lit. If it isn't, press the Auto/Manual select switch.
   • Verify that all four record level controls are set to the center position.
4. Press the round Copy button.
   At this point, the tapes will rewind, the machine will stop, then copying will automatically begin. When the tape runs out, the machine will stop, and all tapes will automatically rewind.
5. Check for good recording
   Check the three red "Short Tape" lights. If one of the "Short Tape" indicators is illuminated and there is a tape in the corresponding chamber, it means that tape ran out before the original was finished. In other words, the end will be cut off. Try again with a longer blank tape. Note that if the chamber is empty, the "short tape" indicator will come on; this is normal.
   It is a good idea to play back a portion of the copy on a cassette player to make sure the copy was successful.
6. Remove the tapes from the machine, turn off the power, and replace the dust cover.

Special Situation: A+A -> AB

The instructions above are for copying one or both sides of a cassette automatically. Sometimes this is not what you want. For example, you can copy one side of each of two originals onto a single cassette. To do this, begin by setting the Auto/Manual mode to Manual. In manual mode, pressing the COPY button only initiates the copy, without rewinding the tape first, and while the tape will still stop at the end, it will not automatically rewind. So load the first original into the "ORIG" chamber and the blank tapes into the "COPY" chambers, and press Rewind to rewind all of the tapes. Make sure the Side Select is set to A, and press COPY. The tapes will stop once the first side has been copied. Now turn the copy tapes over, and put the second original into the "ORIG" chamber, and repeat the process to copy the second side.

A word about cassettes:

Bulk cassettes for duplication are available in the IT for a nominal charge in 60, 90, and 120-minute lengths. The various tape lengths may be identified by looking at the colored stripes on the clear leader:

• C-60 (30 minutes/side): Red stripe, $1.00
