Azimuth Range Meter Owner’s Manual
FOZGOMETER V2 Azimuth Range Meter Correct azimuth alignment of your phono cartridge’s stylus assures the best sound and stereo imaging from your records. To achieve the best performance, your cartridge’s azimuth must be calibrated. The FOZGOMETER V2 incorporates a very sensitive “Log Ratio Detector” to measure the channel separation and channel balance of your phono cartridge. It features higher sensitivity, a new meter design, and AC or battery power for more accurate azimuth calibration.
Prior to Azimuth Measurement Procedure: Mount your phono cartridge with appropriate screws and attach the 4 lead wires, observing proper color connection. Right channel is red plus+ and green minus-. Left channel is white plus+ and blue minus-. Set the Vertical Tracking Force (VTF) per your cartridge manufacturer’s instructions. Align your cartridge (overhang & offset for a radial arm, tangency for a linear arm) and recheck the VTF.
Analogue Productions Test LP tracks: Track 1: 1 kHz sine wave, Both left and right channels Track 2: 1 kHz sine wave, Left channel only Track 3: 1 kHz sine wave, Right channel only Mechanical Meter Check Check your FOZGOMETER V2 with the power both off and on to verify that the meter reads 0. See figure 1. To adjust, power on and turn the black meter trim screw located at the lower middle of the meter until the needle points closest to ZERO.
Figure 2, channel balance ideal Figure 3, Left channel balance off 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.
Figure 4, Left 25 Figure 5, Right 16 3. Play Track 3 on Test LP, the right signal indicator should light. Observe the reading as seen in figure 5. Phono Cartridge Adjustments: Alternate playing track 2 (left) and track 3 (right) test tracks and make small adjustments in Left and Right tilt of the headshell and cartridge until both readings are the same or as close as possible.
Figure 6, Left 18 Figure 7, Right 27 As you adjust Left/Right tilt, you will see the higher channel coming down and the lower channel reading rising. If the readings for both channels are getting closer, continue to adjust the cartridge in that direction. One channel reading may remain constant as the other channel reading is changing. Adjustments should always be done in very small increments. If you overshoot ideal azimuth, the readings may reverse and become more unmatched.
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.
Optimal Azimuth Achieved – Channels Match Figure 10, Left 18 Figure 11, Right 18 Extraneous Meter Movement and Lights: Minimal meter movement may occur with warped or off-center test records or uni-pivot tonearms. The LEDs may illuminate from the system noise floor with no test signal. Disregard these readings until a signal is present. “False” Azimuth Readings: If your cartridge is turned too far in either direction, you may get a false reading.
