Phonostages are devices designed to provide a very high level of amplication. This is necessary

because the electrical signal generated by a phono cartridge is extremely low (usually less than one-

thousandth of a volt). The job of the phonostage is therefore to accurately equalise the phono signal

and boost it to line level (measured in volts).

However, phonostages are by nature extremely sensitive, which leads to the potential problem that

high-frequency interference may also be amplied to a point at which it becomes noticeable.

Unfortunately it is not possible to completely protect the sensitive phonostage circuitry from this in-

terference without degrading its high delity performance. Therefore care must be taken to position

the phonostage away from sources of high frequency interference such as mobile phones, modems

and powerline communication systems (PLC) in which data is sent over the mains power network.

2. Functional description

The Azimuth (the vertical position of the cartridge‘s diamond) is the main inuence on channel ba-

lance, the frequency response and the cross talk between both channels of your cartridge. Optical

control of the azimuth adjustment is not sufcient nor precise enough to ensure accurate adjust-

ment of the cartridge’s azimuth. The exact azimuth can only be determined when using an adequate

measuring instrument like Clearaudio`s azimuth optimizer. The azimuth optimizer 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-amplier 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 amplier makes mobile use of the azimuth optimizer possible!

All headphones with an impedance between 100 ohms and 600 ohms can be used.

The Clearaudio

azimuth optimizer

test record (Art. No.: LPT Azimuth 080108) is necessary to per-

form 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)

Button MM/MC:

Switches the input sensitivity / amplication.

Position MM = 40dB,

Position MC = 60dB

Input impedance/Capacity:

MM = 47kOhm/220pF

MC = 400Ohm/220pF,

(the input impedance is adjusted automati-

cally).

Button L/R:

Switches to the signal-carrying channel of

the test-record

Button Crosstalk:

Activates the operation mode „Crosstalk“

Button „Level“:

Pushing the button ‘Level’ will in combinati-

on with the test-record show the output vol-

tage of your cartridge in the display in mV.

Pushing both buttons ‘Level’ and ‘Cros-

stalk’ simultaneously, the main opera-

tion mode switches between “Phono”

and “Measurement”.

LED “Azimuth” glows blue

4. Measurement operation

Important note!

Besurethatthevolumecontrolofyouramplier(s)is(are)settozero-levelwhiledo-

ing any connections to the azimuth optimizer unit. While using the azimuth Optimizer

in a system as a phono-stage, never switch between MM/MC - mode, damage to your

loudspeakers could occur!

1. Attach the adequate primary adaptor onto the power supply

2. Connect the power supply to the appropriate jack on the back-panel of the

azimuth optimizer

3. Connect the power supply to the mains socket, the azimuth optimizer automatically sets into

operation mode MM and Phono. Now connect the tonearm cable with the

azimuth optimizer

and for playback with the music reproduction system.

4. Choose the relevant operation mode according to your cartridge type: MM or MC.

You can now start with the measurement once all connections have been done correctly:

5. Place the Clearaudio

azimuth optimizer

test record’ (scope of delivery) onto the turntable

platter with side 1 facing up.

Track 1-20 of the test record can be used to adjust and verify the azimuth of the

cartridge:

Track 1 = Signal left channel 1kHz 0dB = 8cm/s (peak)

Track 2 = Signal right channel 1kHz 0dB = 8cm/s (peak)

…

Start your measurement with the left channel (Track 1). Therefore choose the operation mode “L”

by pushing the button “L/R”.

Calibrate the value shown in the display to 0dB by using the control unit in the front panel.

When you now push and hold the „Crosstalk“- button the LED ‘CT’ will glow and the channel

mode switches to ‘R’ - channel. The display will now show the value of the cross talk in dB. Keep

this value in mind and repeat the measurement in the same way with the right channel (Track 2).

Now compare both measurement values with each other. When both values are equal the azimuth

adjustment is accurate. If the values differ from each other you need to re-adjust the azimuth of

your cartridge according to the table below and repeat the measurement until both values are equal.

Before measuring the cross-talk it is important to adjust the signal-carrying channel to

0dB!
