What You’ll Need

  • Source material - our Mag Dubbers can transfer CD, Cassette Tape, and any source with a mini stereo output (eg. Laptops, smartphones, mp3 players, etc.).
  • 2 Split Reels - you can check these out from the DFL along with the Mag Dubber
  • Mag Stock - your editing kit contains 400’ of blank stock
  • 2 Cores - your editing kit contains 12 cores

The following figure identifies all relevant components of the Mag Dubber.

Threading

1. Check that all three of these switches are powered on:

2. Load your mag:

  • Make sure your mag tape is on a core with the matte/record side facing in
  • Put it on a split reel on the left hand side of the mag dubber with the sprockets facing you
  • Fold down the metal pin to lock your split and take up reels

3. Thread the dubber as shown below:

4. Proper tension is extremely important for an effective transfer. Make sure that BOTH the tension rollers float halfway between the stoppers.

Setting Levels

1. Decide how you want to monitor your audio

  • Turn the speaker volume at the top of the rack to about 9:00
  • If you want to monitor with headphones, plug them into the headphone input on the speakers at the top of the dubber.

NOTE: The levels on the meter are most important. FIRST adjust the “Record” dial, THEN adjust the speaker volume so you are listening at a comfortable level.

2. Set the input to your chosen format:

  • Smartphones, laptops, and anything with a mini stereo output will plug into the visitor at the bottom of the dubber (set the input to visitor)

3. Listen and set an input level

  • Press the yellow “Ready” button
  • Turn the volume all the way up on your digital source and listen through the entire recording
  • Adjust the “Record” dial to set your recording level (don't change this during recording)
  • Keep an eye on the VU meter:
    • The needle should land between -3dB and 0dB for the majority of your audio
    • Loud sounds can “kiss” the red but shouldn’t hang out there or else your sound will be distorted

Recording to Mag

Now that your mag stock is properly threaded and you have set your recording levels, you are ready to record!

  1. Turn the top left knob to “A Wind” (This ensures that the motors will turn the right way)
  2. Turn the bottom right knob to “Hold” (This engages the motors)
  3. Turn the top right knob to “Forward” (This will advance your magstock)
  4. Press “Record” and “Reproduce” and press Play on your source material.

When you are done recording, undo the above steps in reverse order:

  1. Press “Safe” (This will stop the Dubber from recording)
  2. Turn the top right knob from “Forward” to “Off”
  3. Turn the bottom right knob from “Hold” to “Off”
  4. Turn the top left knob to “A Wind” to “Off”

Rewinding

Once the machine has stopped, make a mark with a Sharpie at the end of your recording. Rewind your mag on a rewind table. DO NOT rewind your mag on the dubber as it can damage your tape!
