Resistor for unbalanced attenuator
« on: June 06, 2004, 05:20:45 PM »

I have an older Carvin CD recorder in the rack.  I feed the unbalanced rca's across the room into a typical home stereo setup (teac integrated amplifier) for checking cdr's, etc.  While the balanced outputs work fine, everything played through the unbalanced has a moderate, consistent distortion - especially when playing a more modern, heavily 'mastered' release.  I would like to rig up an rca cable with about 6-10 db of attenuation.  Anyone have ideas on values, etc?

Thanks.

10K Ohms in series with the signal, and 3.3K Ohms to ground. That will give you around -10dB with an input resistance of more than 10K Ohm and an output resistance of ca. 3K3

Thanks, man.  I soldered it up this morning and it works great!
