Question about Cambridge Audio Azur 540R Receiver

2 Answers

Sonobuoy deplotyment Hi, I am trying to set up a transmitter-receiver system to record underwater sounds. All I have so far is a heap of old LOFAR sonobuoys (4 types: SSQ906, 981, 937A and 905) and I don't even know what signal (frequency) range the hydrophone covers/ VHF transmitter transmits, whether it is analog/digi signal that gets transmitted and what freq. range the aerial has got to be cut for. Another issue is the system's set-up- which is something I know nothing about and there is limited published information available. Thus I'd be most grateful for advice and comments on what I thought made sense and would work; I reckon ICOM PCR-1500 receiver, which records the raw data (?) straight to a laptop hard drive (?) seems to cover a wide freq range would be a good choice of a receiver (do i need a super-high spec sound card for this?). A remote aerial would aid in maximizing the detection range. The aerial would need to be connected to receiver via an aerial wire (?)and the aerial also has a pre-amp (where?). any guidance will be much appreciated. best regards, l.

You should check out the web site of thales or Ultra for information about both frequencies (Radio and hydrophone).
and you should check the frequency setting option, they all have it.
here is a link that will tell you the Freq. http://www.ultra-scs.com/pdfs/pdf_sonobuoy.pdf

I had Bose lifestyle V35, V20 try to link together. Bose link AL8 transmitter will not connect to receiver. both led is light solid green. Please help.


The commands for the Bose link system are actually going through the remote control system. In order to use the system you need not only a set of AL8 sender and receiver, but also a special remote control model RC48S2-40 these model numbers are slightly different for the US and for Europe. In addition you will need to activate the BoseLink connection through the system settings menu and you will need to tell the remote to which system it needs to talk. When you have done all that, there should not be any problem to "connect" the two systems. If this does not work, you may need some specialized help from a Bose specialist who understands this multi room set-up.

I have wireless speakers and the transmitter stopped working. Nothing happens when you plug it in--??? It's only a month old. AW872


Hi I also post in here , so that you can let me know how it goes.

Try unplugging the transmitter from power adapter, if it also has batteries remove them. Also unplug transmitter audio cable.

Then remove batteries/unplug adapters from speakers.

Wait few minutes and reconnect the system.

This is a proper hard reset, and can fix minor problems.

If when you re connect the transmitter does not glow, or you do not have sound on one or both channels then there is a fault.

Check the transmitter audio cable, a short in there can cause troubles.

If you find no problems , then unit is defective, as it is under warranty contact Acoustic Research to validate the warranty here and get the transmitter or the whole set replaced.

SAMSON CO1U recordings sound like they're underwater on my MAC


The behavior you describe suggests that the mic is not getting power. Since it is a condenser mic, it requires what is usually called "phantom power". This should be provided thru the USB port. Check to be sure that the USB port is supplying that power. Check with another port for example. If that fails, you may have a defective mic.

Keep us posted.

Page 93 on user's manual.

After that press REC PAUSE on camcorder and start your VCR or underwater camera.

Good luck!

Could be a bad patch cord, a setting on the mixer, a faulty mixer (unless it works ok with other amps), or a dirty control on the Sony amp if it has analog controls. Have you tried connecting other sources to the Sony?
