Cambridge Audio Azur 551P Preamplifier F.A.Q.

How do I connect the Cambridge Audio Azur 551P to my turntable and amplifier?

To connect the Azur 551P, plug your turntable's RCA cables into the input sockets labeled 'IN'. Connect the 'OUT' sockets to your amplifier using another set of RCA cables. Ensure the ground wire from your turntable is connected to the grounding post on the 551P to prevent hum.

What should I do if there's a humming noise from my speakers when using the 551P?

Check that the ground wire from your turntable is securely connected to the 551P's ground terminal. Also, ensure all RCA connections are tight. If the hum persists, try repositioning your cables to avoid interference from other electronic devices.

Can I use the Azur 551P with a turntable that has a built-in preamp?

If your turntable has a built-in preamp, ensure it is turned off or bypassed when using the Azur 551P. Using both preamps simultaneously can lead to distortion and poor sound quality.

What is the proper way to clean and maintain the Azur 551P?

To clean the Azur 551P, use a soft, dry cloth. Avoid using any liquid cleaners or solvents. Regularly check connections and ensure the unit is not exposed to excessive dust or moisture.

Why is there no sound output from the Azur 551P?

Ensure that all cables are securely connected and the turntable is properly set up. Check that the amplifier is set to the correct input source. Verify that the Azur 551P's power supply is connected and the LED indicator is lit.

Is the Azur 551P compatible with both moving magnet and moving coil cartridges?

The Azur 551P is designed for use with moving magnet (MM) cartridges only. It does not support moving coil (MC) cartridges.

How can I improve the sound quality of my Azur 551P setup?

Ensure your turntable is properly balanced and the cartridge is aligned. Use high-quality RCA cables and make sure the ground wire is connected. Placing the 551P on a stable, vibration-free surface can also enhance sound quality.

What power supply does the Azur 551P require?

The Azur 551P requires a 12V DC power supply with at least 75mA current capacity. Ensure you use the power adapter that was provided with the unit or a compatible replacement.

Can the Azur 551P be used in a home theater setup?

Yes, the Azur 551P can be integrated into a home theater setup by connecting it to an AV receiver or dedicated stereo amplifier with a phono input. Ensure that the receiver or amplifier has a line-level input available for the 551P's output.

What should I do if the LED indicator on the Azur 551P does not light up?

Check that the power adapter is firmly connected to both the wall outlet and the Azur 551P. Ensure the outlet is functional. If the issue persists, consider testing with a different compatible power adapter or contacting customer support.
