Beomaster 4500 no stereo on AUX/CD/TP1 inputs

[Veso Kossev]

Greetings,

I recently acquired a Beomaster 4500. When listening in FM mode the unit work perfectly. I got a 5DIN to 3.5m cable to connect my AirPort Express and be able to airplay music wirelessly from my phone. When I do so, I only get audio on the right channel, regardless of which speaker bank I plug in the speakers too. When I switch to FM mode, stereo works just fine. I have moved the 5DIN cable to all sources (AUX/CD/TP1/TP2) and same result. I also tried a 7DIN to 3.5m cable and same results. The seller said the unit worked normally in stereo mode when used with a BeogramCD player. Any advice on what could be my issue and how to properly play music wirelessly via AirPlay in stereo mode? Thank you all for the help,

-Veso

Hi and welcome to Beoworld!

A couple of simple things to check (apologies f you have already done so!)

• Have you checked the Airport Express with another amplifier/headphones to see if the fault is there? (perhaps a faulty 3.5mm socket?)
• Have you checked the balance setting in the iPhone from which you are AirPlaying?  (Go to Settings   > Accessibility > Audio & Visual and adjust the balance on the slider at the bottom)
• Have you tried another device connected to the BM4500 input? Perhaps connect the phone directly and experiment with the balance setting as above.

Ok I tried connecting my phone directly to the Beomaster via a lightning to 3.5m adapter – same result, only sound on right channel. Switch to FM, all is good. I checked the balance settings on my phone and it was set on dead center. I read on a FB group that a 7DIN cable won’t work for stereo so I got a 5DIN and same result…

Both 7-pin and 5-pin DIN cables should work as long as the audio signal (L&R) is routed to pins 3 and 5 of the PIN plug, which they usually are (pin 2 is signal ground – pins 6 and 7 used for data).  You could check with a multimeter.

Picture shows solder side of plug, or looking into socket:

If you are confident of the cables, it is time to look for a fault internally – the service manuals are available on Beoworld for Gold/Silver Members.
