KAB RF-1 connection


Stupid question. If I want to use the phono section on my McIntosh, how would I connect the RF-1 to the amp?  Can I connect the RF-1 to the tape loop or do I need to get a stand alone phono and connect it after that?

I use mine on a processor loop on my Mac preamp.  I play through the moving coil input and engage the processor loop when I want to use the filter.  I have had mine for at least 8 years, it’s loaded with audiophile parts.  A tape loop will work.  Don’t put between the preamp and amp because then you will be using it all the time.  Don’t forget to plug it in. 
I don’t know if the MA6900 has one. I am using McIntosh separates. You can use the tape loop if you have one, same thing as the processor loop.
