Sorry to jump in. I have a yamaha rx3050 and i'm hoping some one here has the same sort of setup, that i will explain, and can tell me if I have hooked it up right or what to do to get the most out of the gear i have. First, I have my room and speakers setup in Dolby Atmos config. 7x2x4. My primary is the 3050 I also have the Yamaha A1 as the external amp. I have definitive Tech Bp2000's as my fronts, c2002 as my center, BPX's as my rear surround and bx2's as the sides, also 4 ceilings speakers, these are speaker tiles, can't remember there name of them, but they look like ceiling tiles, and i have 4 chairs hooked up to bass shakers in a Series-parallel config. I also have a 2 front and 1 rear subs.
Ok, the hook up's, I have hooked up the speakers with just knowledge of how i've always hooked them up with No real technical know how of why I hook them up this way. So keep that in mind as you hear how it's currently hooked up the way that it is. I put the "L+R Front's" speaker wire to the Yama A1's "main" speaker IN's to drive them separate along with the RCA pre-out "Front" of 3050 to the A1's "main" in RCA to send the signals to A1. The Defin Tech. speaker Posts, i have the Mid & HI jumped together and "low posts" left alone, the speaker wire is wired into the Mid's posts, and a LFE cable is plugged into the speaker LFE IN and it comes from the 3050's Front sub out which I "Y'ed" the cable to go to each front speakers subwoofer. The "Rear surrounds" are wired into the A1's surround speaker out posts and the RCA's from 3050's "surround" pre-outs to the A1 RCA "surround" IN. I'm curious in my configuration of these if the Rear surrounds & Surrounds are not plugged in right seeing there not named the same on the A1 & 3050? Anyway, So these 4 speakers (Fronts & Rear surrounds" will be driven by external amp, A1. I have the "center" into the 3050 "center" posts and "side" speakers into the 3050's "surround back" posts, (wondering if those should be wired into the "Surround" posts instead?) I have the "front ceiling" connected to the "SP-1" Speaker outputs on Yama 3050 and the "rear ceilings" to the "SP2" of the 3050. I have the "Rear Sub cable" coming out of the 3050's "sub out" going to the "rear sub's" IN. The last is the Shakers in the chairs. I have ONE speaker wire +,- coming for the chairs and that is because of how they are wired, series-Parallel, I have taken this wire and wired it to the 3050's "Front", left +,- speaker post OUT because it will put out the low base frequency's that i need going to the shakers. I'm not sure if this is wired right to get the most out of my equipment? I have Not tried any of this yet (Turned on the Yamaha's) because i don't have a tv yet so I can program the 3050.
Sorry for the long story but i wanted you to know how everything was hooked up so you could hopefully help. Thanks
