    Post pioneer aux in help

    I am about to do the aux in hack for my pioneer DEHP4300R. I have found the diagrams from searching but there are 2 different schematics. On one diagram the pin on the middle row is used for the common ground/left channel -. But on the other it is used for left channel +. Which diagram is correct since I read that some people were having problems with distortion and the input being too quiet. [img]null[/img]

    The 2nd pic is correct....the ground for Left is on the top not the middle....have tried it on the DEH-P3150....its a little bit softer and the rear speakers seems not to be working...other than that ...it should be fine...

    1st row R+, R-, L-
    2nd row L+

    hey i have used the top pic for my Pioneer 8250 and it works like a gem ... no distortion what soever also no volume drop ..

    So i guess i vote for the top pic..


    Mastero

    matter of fact the both are correct its just the qus of polarity..

    someone posted the circuit diagram of the CD-RB20 before...

    there are some amplification within the CD-RB20 for the AUX in....that should be the reason why the volume is softer

    normally would hook up to the headphone output(instead of lineout) from the source...this way the "pre-amp" circuit is not really required....

    now still trying to find out what is the required p-p voltage before distortion....

    sockman: this might help. from the crutchfield website (goto the pioneer cd-rb 10, then detailed info)

    "The device connected to the RCA ins must either have an output voltage of 1 volt or less OR have a volume control so that its output can be lowered. Without this this unit will distort and/ or be damaged"

    the link might help if it works

    http://www.crutchfield.com/cgi-bin/S...fo&i=130CDRB10

    I suspect they mean 1volt rms, but you never know, it might be peak2peak. Let me know how your tests go, as i also want to get my input levels perfect

    the bottom one is right , but check the polarity on the left channel
    as it could be reversed.......

    MikeHunt: the input (to CD-RBx0) should be 1v p-p "standard" RCA line out??...the problem now is the output from CD-RBx0 to the HU...maybe we need someone with the unit to give us the info....

    tried using the headphone output...doesn't really change the volume level....

    i'm guessing 4v p-p for the output from (CDRBx0)....
