I started to build a new set up based on gorgeous Beocenter 9500 and found some difficulties with this project. Please help me ).
I need to connect a network streamer (500mV / 800mV / 1V / 2V - 2 RCA Line-Out) to the 9500. When I check a back plate of the 9500, I found a 3 ports for it: Tape 2, AUX & Line-In/Line-Out. In service manual I read what Tape 2 & AUX have 36mV sensivity (which is very low). Standart for Line-In/Line-Out is 500mV (but I found nothing about this port it in the service manual). Only on diagramm in the Beocenter 9500 Setting Up Guide we see remark about this port: Line-In/Line-Out "do not remove dummy plug if not in use". When we remove it we can see what this dummy plug has 2 briges 1-3 (left input / output) & 4-5 (right input/output), that is loop.
When I try to connect 2 RCA to 5DIN cable to Tape 2 or AUX - I hear the test signals (in both pairs of connected speakers: passive through Speakers 1 and active through Power-Link 1). When I try to connect RCA to 5DIN to Line-In/Line-Out - I hear nothing. Also I hear nothing if I try to listening CD, Turntable or Tape 1 when 2 RCA to 5DIN connected to this Line-In port.
So question is how to turn on this Line-In port for streaming audio from external DAC?
