I recently got a Beomaster 5500. I have not tried it with speakers. I am running it with a Beogram cd5500.

I have connected my Beoplay H95 with the original cable.

The sound coming is very noisy/distorted. The higher the volume, the worse it sounds before the sound cuts.

It’s been 7-8 years since I last opened one of these up, so any guidance and help would be appreciated ?

It’s just a guess, but it sounds to me like you’re overloading the input of the H95s. If the input signal is high enough, it will cause the headphones to shut down to protect themselves.

Try turning down the volume on the Beomaster 5500 and see if this helps.

Thanks for solving my problem (or lack of error searching skills), Geoff ?

No worries! I found this one out for myself when I connected a pair of H95s to the output of a refurbished Beogram turntable (I was checking a prototype of the RIAA preamp that we put in the 4000c series).

I wasn’t listening to distorted audio for long before the headphones turned themselves off. That was when I realised what should have been obvious – the new RIAA can output about 7 V peak, and the headphones are designed for a 1 V RMS (or 2 V RMS? I can’t remember…) (therefore 1.4 Vp (or 2.8 Vp)). The poor things were just trying to protect themselves from my abuse… 😀
