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. Readings
are made directly from your tonearm. The FOZGOMETER
V2 optimizes your cartridge’s azimuth using the Analogue
Productions Ultimate Test LP.
Line contact and Micro Line styli have a very small groove
contact area as compared to elliptical styli, thus requiring
finer adjustment. Proper azimuth will result in the highest
channel separation and best channel balance.
The FOZGOMETER V2 measures channel separation and
channel balance as you horizontally adjust your cartridge’s
azimuth to get the best readings.
The very sensitive FOZGOMETER V2 can measure small
differences between the cartridge’s left and right channels,
based on the cartridge design and construction. Achieving
the closest measurements, even if not identical, will result
in higher performance and better sound.
Matching the readings for the 2 channels is the goal. The
strength of the readings, or how high the needle goes up
in the meter, is based on the cartridge’s generator design
and output. The strength of the readings is less important
than the close matching of the 2 channels.

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. Next,
set the Vertical Tracking Angle (VTA/SRA) and anti-skate
per your cartridge and tonearm specifications.
FOZGOMETER V2 Power:
Connect the supplied outboard power supply to the
FOZGOMETER V2 and plug into an AC power socket.
You will need a plug adaptor for non-UL sockets. To
switch to battery operation, open the unit, removing
the four large Phillips head screws in the faceplate.
Disconnect the internal connector and install the
supplied 9-volt battery. Close the unit and reinstall the
4 screws. Please note you can only use AC or battery
power based on internal configuration.
FOZGOMETER V2 Connection:
Connect your tonearm cable left and right RCA
connectors to the corresponding left and right input jacks
on the FOZGOMETER V2. You can also connect the
FOZGOMETER V2 to the output of your phono preamp
and when using an optical cartridge with equalizer.
Analogue Productions Test LP:
Use the Analogue Productions Test LP #AAPT1,
available from your Fozgometer dealer, for azimuth
calibration. The following instructions detail using the
FOZGOMETER V2 with Side 1, track 1 for channel
balance, and Side 1, tracks 2 & 3 for channel separation.

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.
Patience is a Virtue:
Given the small profile of
modern styli, adjusting
azimuth may require many
small adjustments. Figure 1, Meter 0
Azimuth Measurement Procedure:
Lower your phono cartridge on the stationary Test LP.
Visually examine cartridge lowered on test record,
viewing from the front. Adjust tonearm headshell
so top of cartridge is parallel to record surface. You will
use this physical adjustment of your tonearm headshell
later to fine tune azimuth. Cue up your tonearm.
Channel Balance:
Turn on your turntable to 33.3 RPM and play Track 1 on
the Test LP. If the channels are balanced, the meter will
read near zero and only the CENTER light will illuminate.
See figure 2.
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. Always start with your cartridge
visually parallel to the record to avoid false readings
Set-up Tips:
All cartridge set-up parameters are inter-related, so
always check all parameters of your set-up after making
any changes. Re-check your set-up on a new cartridge
after the break-in period. Check your cartridge set-up
every year to verify everything is properly adjusted to
ensure your system is sounding its best.

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.
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. 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.

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.
If the right channel reading is lower than the left
channel, as in figures 4 and 5, you typically turn the
headshell and cartridge “counter-clockwise” when
looking at the tonearm from the front.
If the right channel reading is higher than the left
channel as in figures 6 and 7, you typically turn the
headshell and cartridge “clockwise” when looking
at the tonearm from the front.
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.
Locking Azimuth adjustment on Tonearm:
If your headshell or tonearm features an Azimuth
locking device, you should lock the arm after each
adjustment. Always double check your readings after
locking to assure best accuracy.
