What Are the Advantage of an 11-channel Amp?
The X11 is a big amp for big systems. If your home theater uses smaller satellite speakers, the X11 is probably overkill. However, if you have larger front channel (LCR) free-standing or in-wall/ceiling speakers and a lot of space to fill, the X11 is ideal, especially for driving a 7.2 or higher channel surround sound systems. With 11 amps in one 10 RU chassis, the X11 is more effective at delivering power than connecting multiple two-channel amplifiers and far more reliable than relying on an A/V receiver. Plus, you’ll always have room to expand with more speakers should the urge hit you down the road.

Chris Talas • 05/08/2020, 8:21:25 PM Q What is the actual 8 ohm output per channel? I have 2 amp 300, an adcom gfa555 and a speaker craft amp now, running the 2osd amps bridged to the mains and the other 2 amps doing 2 speakers on a zone in the front deck and 4 speakers on a separate zone on the back deck. I'd like to consolidate and power my 9.2 (actually running 3 subs, 2 stereo in front and a single behind couch and the 2 zones with less equipment but I want to make sure that I'm not going to lose ground

A Hi Chris: That is a whole lot of horsepower. Ironically the OSD-300 was based upon the GFA-555 design(circa 1984).The OSD-300 is rated at 150 watts at 8-ohms stereo, Bridged Mono at 8-ohms: 470 Watts. What subs are you running.
