I find the best way to connect any equalizer is to connect via the tape monitor sockets, assuming that the AVR has one. From the equalizer in and out sockets - connect the Eq OUT to Tape IN on the AVR. And Eq IN to Tape OUT on the AVR. Some AVR don't allow connections, due the equalizer interfering with Surround Sound systems. If you can connect switch off the equalizer when listening to Dolby or other surround formats, as it will spoil the sound.
