What to do if the Cambridge Audio azur 651R remote control is not working?
If your Cambridge Audio Receiver's remote control isn't working, first, replace the batteries. If that doesn't solve the problem, try moving the remote closer to the receiver, ensuring you're within its effective range.
Why is there no sound from my Cambridge Audio azur 651R Receiver subwoofer?
If you're not getting any sound from your subwoofer, check that the subwoofer hasn't been set to 'Off' in the OSD setup menu or via the remote. Change the setting of the subwoofer from 'Off' to 'On'. Also, if you've selected DTS Neo:6, DD Dolby Pro Logic II/IIx modes (which have no LFE channel) with all speakers set to 'Large' (and bass augment off), change the mode selection or speaker size settings.
What to do if Cambridge Audio azur 651R sound cuts off or there is no sound?
If the sound cuts off when listening to music or there is no sound even though the power is on, it could be due to a couple of reasons. First, the speaker impedance might be less than prescribed for the 651R/751R, so use speakers with the correct impedance. Second, the unit might not be adequately ventilated and is overheating, so ensure the unit is adequately ventilated.
How to fix no sound from the center speaker on Cambridge Audio Receiver?
If you're not getting any sound from the center speaker, it might be that the center speaker has been set to 'None' in the OSD setup menu. Change the center speaker setting from 'None'. Also, if a stereo mode has been selected, select a surround sound mode instead.
Why is there no sound from the rear speakers on my Cambridge Audio azur 651R?
If you're not getting sound from the rear speakers, there are a few potential causes: * The source being played might not be recorded in surround sound, so ensure the source is recorded in surround sound. * The speaker/s might be set to 'None' in OSD setup menu, so change the speaker setting from 'None'. * A stereo mode might have been selected, so select a surround sound mode instead of stereo mode.
What to do if there is no sound from Cambridge Audio azur 651R speakers connected to a digital input or HDMI?

How to troubleshoot no sound from Cambridge Audio Receiver speakers connected to an analogue input?
If you're experiencing no sound from speakers connected to an analogue input, it could be that the audio input type is set to digital. Press the Audio Input Type button to switch to analogue. Alternatively, the audio input type can also be set in the Input/Output Setup menu of the OSD, so adjust the input type setting there.
What causes sound not audible from one channel on Cambridge Audio Receiver?
If sound is not audible from one channel, it could be due to speaker connections being disconnected, so check and reconnect the speaker connections. Another reason could be the speaker being set to 'None' in the OSD setup menu, so change the speaker setting from 'None'.
How to eliminate a low hum or buzz sound from Cambridge Audio azur 651R?
