You will play the reproduce alignment tones and adjust the reproduce level, high frequency equalization, and low frequency equalization of the tape machine's electronics.
1) Locate the 1 kHz tone on the alignment tape and park the tape at its beginning.
2) Adjust "Reproduce Level" control so that the 1 kHz tone reads 0 VU.
(Do this adjustment while playing the 1 kHz tone form the tape.)
To do this, first locate the correct adjustment control on the reproduce adjustment section of the electronics. Notice that the machine has many different "holes" in which to place your alignment tool (commonly called a "tweaker"). Before you start, read the surface of the electronics plate and make sure you understand what each trim pot controls. There is one "Level" control for each speed of the tape transport. Make sure you are adjusting the correct trim control. Now find the control marked "Level" on the Reproduce Adjustment card for the speed you are playing (Fast). With your tweaker, turn the control until the VU meter reads 0 VU.
3) Locate the 10 kHz tone on the reproduce alignment tape.
You will find it in the frequency response section of the tape.
4) Adjust "Reproduce High Frequency Equalization" control so that the 10 kHz tone reads 0 VU.
Do this adjustment while playing the 10 kHz tone from the tape.
To do this, locate the Reproduce Adjustment electronics. Now find the control marked "High Frequency Equalization" for the speed you are playing (Fast). With your tweaker, turn the control until the VU meter reads 0 VU.
*Re-Checking Level after a High Frequency Alignment
If you find that you have had to make a very large change in the high frequency adjustment, you will have to go back and re-check your level at 1 kHz. (This is because there is an amount of interaction of the high frequency circuit at 1 kHz and so a large adjustment of the high frequency equalization circuit might affect the 1 kHz, so check it again.) If you do make a re-adjustmentof the 1 kHz signal, you will have to go back and do the 10 kHz signal again as well.
*Low Frequency Alignment
If there is no compensation on the tape, then you cannot do a reproduce alignment of the low frequency at this time. You must do it when you do the record alignment, which follows this operation. The only exception to this is if you are aligning a full track mono tape machine.
In order to help you decide whether or not you should do a low frequency alignment now or later, answer these next few questions:
Your alignment tape (is, is not) correctly compensated for the machine you are aligning.
- Based on the above answer, you (can, cannot) do a low frequency alignment at this time.
- Your alignment tape has no compensation at all and none is needed due to your head configuration, so you (can, cannot) do the low frequency alignment that follows.
If you determine that you can do a low frequency alignment at this time, proceed to the following steps.
5) Locate the 125 Hz frequency tone on the reproduce alignment tape.
You will find it near the beginning of the frequency response tones section of the tape, right after 63 Hz.
6) Adjust the 15 ips "Reproduce Low Frequency Equalization" control so that the 125 Hz tone reads 0 VU on the meter while the tape is playing.
To do this, locate the Reproduce Adjustment electronics. Now find the control marked "Low Frequency Equalization" for the speed you are playing (Fast). With your tweaker, turn the control until the VU meter reads 0 VU.
*Re-Checking Level After a Low Frequency Alignment
If you find that you have had to make a very large change in the low frequency adjustment, you will have to go back and re-check your level at 1 kHz. (This is because there is an amount of interaction of the low frequency circuit at 1 kHz and so a large adjustment of the low frequency equalization circuit might affect the 1 kHz, so check it again.) If you do make a re-adjustment of the 1 kHz signal, you will have to go back and do the 125 Hz signal again as well.
