I just need some assistance on what inputs/outputs to use for my Marantz 4270 I have the following items to run thru it: a) MArantz CD5003 b) Teac Graphic Equalizer c) Akai Reel to Reel d) Tascam cassette deck right now I have the CD audio out plug into the Equalizer In, and have the Equalizer out plugged into the Cd/Aux on the back of the unit. This works fine. I just want to be able to use the graphic equalizer on all of the units without having to unplug each and everytime I want to change units.
