2. Functional description

The Azimuth (the vertical position of the cartridge's diamond) is the main influence on channel
balance, the frequency response and the cross talk between both channels of your cartridge.
Optical control of the azimuth adjustment is not sufficient nor precise enough to ensure accurate
adjustment of the cartridge's azimuth. The exact azimuth can only be determined when using
an adequate measuring instrument like Clearaudio`s azimuth optimizer. The
measures the cross-talk from the left to the right channel and vice versa. The ideal cartridge position
is when the azimuth has been adjusted accurately so that both measurement results are identical.
Additionally, you can measure the output voltage of your cartridge by using the operation mode
« Level » To use this operation mode it is necessary to set the input sensitivity to the MM-mode!
Further more there is a High-End phono-pre-amplifier built in as well, so that you are able to check
the sonical result of the correct adjustment in your music reproduction system.
An integrated head-phone amplifier makes mobile use of the azimuth optimizer possible!
All headphones with an impedance between 100 ohms and 600 ohms can be used.
azimuth optimizer
The Clearaudio
perform the measurements and is included with your Optimizer.
For measurement, the following tracks of the azimuth optimizer test record are required:
Track 1 = Signal left channel 1kHz 0dB = 10cm/s (Peak)
Track 2 = Signal right channel 1kHz 0dB = 10cm/s (Peak)
...
Track 19 = Signal left channel 1kHz 0dB = 10cm/s (Peak)
Track 20 = Signal right channel 1kHz 0dB = 10cm/s (Peak)
