i have linked five receiver's together, by record out to auxillary in on next, and so on, my first yamaha v2095 has an eq-500, hooked to it, my question is, in this set up, will this one equlizer, pass through all units, or will i distort output by adding an equlizer per unit? i like the increased db output, also wondered will an equlizer affect the quality of output of my subwoffer's?
