<DIV>I just realized that the DSP should be able to strip PL off. At least I think it can.</DIV>

<DIV>I need help, I am using a Mastr II and a URI. I want to use the vol/sql hi for my discriminator audio. I was going to use a resistor divider to pad down the audio. </DIV>
<DIV>Has anyone ever done this? Could you explain it in more detail to me. I've read you take the two resistors and put them in series. I would tap my URI in the middle where those two resistors meet. I assume one end goes to vol/sql hi, but where does the far end go?</DIV>
<DIV>Thanks for your help</DIV>
