So I have an old 1980s Technics receiver with both Pre-Out and Main-In for 2 channel.

I have the Pre-outs connected to an separate amp. Now, i also have a sacd player and connected the front L and R analog output from the sacd player to the Main-in on the technics. Problem...there is no sound. The EQ dances on the receiver and the sacd players is playing. The menu on the sacd player is correct.

Question: I have no AUX input to press on the receiver..so when i press all the other inputs there is no sound. The owners manual doesn't mention what to press when using the Main-ins.

I have it now connected to the CD input and I can hear music, but not sure if this is the full sacd sound? Any issues using this input?

thanks!
