Cambridge Audio Azur 851A Amplifier F.A.Q.

How do I connect my Cambridge Audio Azur 851A to a Bluetooth device?

The Azur 851A does not have built-in Bluetooth capability. To connect a Bluetooth device, use an external Bluetooth receiver connected to one of the amplifier's audio inputs.

What is the best way to bi-wire speakers with the Azur 851A?

To bi-wire, connect one set of speaker cables to the binding posts labeled "HF" and another set to the "LF" posts on the speakers, ensuring both sets of cables are connected to the corresponding terminals on the Azur 851A.

Why does my Azur 851A shut down unexpectedly?

Unexpected shutdowns can be caused by overheating. Ensure the amplifier has adequate ventilation and is not placed in an enclosed space. Check for proper speaker impedance and short circuits in speaker wiring.

How can I perform a factory reset on my Azur 851A?

To perform a factory reset, turn off the amplifier, then hold down the 'Speaker A/B' and 'Direct' buttons while turning the unit back on until the display shows the reset confirmation.

What should I do if there is no sound from my speakers?

Check if the correct input source is selected and if the volume is turned up. Ensure that the speaker cables are properly connected and that the speaker impedance matches the amplifier’s specifications.

How do I clean the exterior of my Azur 851A?

Use a soft, dry cloth to wipe the exterior. Avoid using any liquid cleaners or solvents that may damage the surface.

Can I use the Azur 851A with a turntable?

Yes, you can connect a turntable to the Azur 851A, but you will need an external phono preamp unless the turntable has a built-in preamp. Connect the preamp output to one of the line-level inputs on the amplifier.

How do I update the firmware on my Azur 851A?

The Azur 851A does not support user-updatable firmware as it is an analog amplifier with no digital processing components.

What are the optimal settings for the Azur 851A for home listening?

Optimal settings vary based on room acoustics and personal preference. Generally, start with 'Direct' mode enabled for pure sound, and adjust bass/treble controls as needed for your listening environment.

How do I troubleshoot distortion issues with my Azur 851A?

Check the speaker connections and ensure the impedance matches the amplifier’s capabilities. Verify that the source device is not introducing distortion and that the amplifier is not being overdriven.
