Compatible TV to audio receiver


Read some confusing things and just wanted to confirm, I have an older television with an audio out listed as  470 mVrms, 1k Ohm  and the receiver is listed as audio in of 200 mV with 50k Ohms.  (note this is how they are listed in the specifications.   

for the TV that is for the "fixed" output setting.   I had to change it to variable and control from TV and turn the volume way up to get proper sound from receiver.  didn't seem like I should have had to do that.

Thanks

Thanks for the explanation.  I thought since the "sensitivity" of the receiver was 200 mV, then we should have been fine.

I have a phono jack for a unit that needs preamp with 2.5 mV sensitivity but the S/N is a low 74db.   I would assume stick with the previous option.

Question, does increasing the voltage improve S/N value?  I would believe so.  But I imagine I could go too high.   the specs don't tell me the peak voltage output would be on variable.
I figured phono was a bad idea.    

the inputs  for sound for video devices on my receiver says the "sensitivity" is 200 mV.    Its my understanding the lower the input sensitivity, the lower the output from the player device that was needed.    Note this is an older model receiver, we're setting up for my son.
