I had a "IR-converter" that looked much like a "X-tra Speaker Kit" wich i recall was able to be used with diffrent of pre-beolink1000 models, including Beomaster 5000 (i might be wrong tho). I traded my for a real "X-tra Speaker Kit" wich was what i wanted when I bought it.
Traded it with Peter here on site :D since he was very intrested in the manual.
