Getting both channels to match or read as close
as possible is the key.
Figure 8, Left 21
Figure 9, Right 19
Azimuth is calibrated when the left and right signal readings
read as close as possible, as in figures 8 and 9 with Left at
21 and Right at 19. Optimal azimuth is achieved as seen in
figures 10 and 11 with both readings at 18.
Matching the reading of the 2 channels is the goal. The key
is to get both channels to measure as close as possible,
ideally the same. The strength of the readings, or how high
the needle goes in the meter, is less important than the
matching of the 2 channels.
Channel Balance Check:
After setting azimuth, go back and check channel balance.
If it is not measuring better than your first channel balance
reading, you should redo azimuth adjustment for best
readings for both channel separation and balance.

If channel balance is off, the CENTER light will
illuminate and a channel light, signifying that channel’s
imbalance, will illuminate with the meter displaying the
amount. The more intense the illumination also indicates
higher channel imbalance. Take note of the imbalanced
channel and the amount. After adjusting azimuth as
detailed below, re-check your channel balance.
Azimuth Adjustment:
1. Turn the power switch to the “on” position. With no
track playing, only the SIGNAL DIRECTION CENTER
light will illuminate, and the meter will read zero.
2. Play Track 2 on Test LP and the LEFT SIGNAL
DIRECTION indicator should light (if the right indicator
lights, the channels are reversed and need to be
corrected). Note the meter reading as in figure 4.
