My CD player technics SL-PS770D have 2V output voltage as many CD players on market. I must to connect WiFi transmitter on the CD analog output but as CD player have 2V on its output then I have overboosted output from WiFi receiver. On all my other audio equipment I dont have this problem and all work perfect.
Fore that reason I do some research to resolve this problem but I'm not so sure if that's the right way.
This is schematics from my CD Player...
I want to change resistors R829 and R830 with different resistors values and attenuate output voltage on 200mV or 250mV. I use online calculator to calculate how much -dB is need to attenuate this signal to adequate voltages and calculator show me this results...
I`m also found different calculator what measure how much we need resistance to make voltage divider and it calculate that, if I keep output impedance on 47kOhm, I need to change resistors R829 and R830 to 205 kOhm for -19.78dB/205mV output or use 162 kOhm resistors for -17.95dB/253mV...
This is that calculations...
I need some help to confirm me is all of that can to be correct or not?
Thanks to all...
