IM CONFUSED ON HOOKING UP THIS ROSS SYSTEMS R-15S 15 BAND 2 CHANNEL EQ TO MY RECEIVER AVR687 DENON THIS EQ ON EACH HAS 3 RCA JACKS THAT SAY 'UNBALANCED OUTPUT'BALANCED OUTPUT'AND BAL/UNBAL INPUT. DCONT HAVE AN IDEA HOW TO HOOK UP TO MY RECEIVER.
There is no practical way to hook it up. This model of Denon does not have pre amp out / power amp in connections. Therefore, there is no good way to connect it. A better model would have those connections, but this one does not.
Also the Ross EQ, made in Taiwan, imported by the defunct international music corporation, was not actually made for stereo hi fi use. It has 1/4" phone plug connections for PA systems. The audio level is much higher than a audio video receiver provides or receives.
So even if you bought RCA to 1/4" phone plug adapter cables, the audio levels would not match correctly, and there would be all kinds of goofing around, since there is no correct way to plug it into the Denon.
Sorry about that.
