Product Information

Azimuth Optimizer

The azimuth optimizer is a high-end product made by Clearaudio electronic GmbH in Germany. It is a measuring device for cartridge adjustment with an integrated phono preamplifier to amplify the signal of the phono cartridge. The device is designed for use in heated rooms and should only be set up on leveled surfaces. The intended use of the azimuth optimizer is in accordance with the information provided in the user manual only. The power supply may only be operated with maximum permissible connection values according to the technical data.

Phonostages provide a very high level of amplification, to address the fact that the electrical signal generated by a phono cartridge is extremely low. As a result, phonostages are extremely sensitive, which leads to the potential problem that high-frequency interference may also be amplified to a point at which it becomes noticeable. Unfortunately, it is not possible to completely protect the sensitive phonostage circuitry from this interference without degrading its high fidelity performance.

Usage Instructions

Before using the device for the first time, check for visible damage. Do not connect the device to the mains if it is damaged. If it has been dropped or gotten wet, contact your dealer to have the device inspected. Never expose the device to rain or moisture and never touch the power cord with wet hands. For your own safety, regular visual inspections of any defective insulation on the connection cable are also recommended. A damaged cable should be replaced immediately by a specialist. Never pull on the power cable to unplug the device, but directly on the plug. The inside of the device is maintenance- free, never open the housing or try to repair the device yourself, as this may lead to loss of warranty. If you do not operate the device for a longer period of time, disconnect the power supply from the mains.

The device should only be set up on leveled surfaces and in a location without direct sunlight, temperature fluctuations, or high humidity. Avoid placing electronic devices near heaters, heat lamps, or other devices that produce heat. Never block the ventilation slots or cover the device with a cloth or similar. No objects with an open flame may be placed on the device (burning candles or similar). Remember that the azimuth optimizer is a measuring device for cartridge adjustment with an integrated phono preamplifier to amplify the signal of the phono cartridge. Use it according to the instructions provided in the user manual only.

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 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-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.

The Clearaudio azimuth optimizer test record (Art. No.: LPT Azimuth 080108) is necessary to 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)

Measurement operation

Important note

Be sure that the volume control of your amplifier(s) is (are) set to zero- level while doing 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)
  1. 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!

Follow these advises to adjust the azimuth:

measurement| Left channel (display)| Right channel (display)| Direction of cartridge- rotation
---|---|---|---
L – R (Track 1)| 0| -30dB| Azimuth is O.K.
R – L (Track 2)| -30dB| 0
L – R| 0| -35dB| Rotate cartridge clockwise
R – L| -25dB| 0
L – R| 0| -25dB| Rotate cartridge counter clockwise
R – L| -35dB| 0

Note: The measurement values in the table are only used as examples and can be different depending on the type of cartridge.

Troubleshooting

  • If you have a problem with your azimuth optimizer , first check the possible causes to rule out incorrect operation.
  • If the error persists, please contact your dealer!

Never try to open the device and/or repair it yourself, this will void the warranty!
