A 7200 is a power full beast. When you get your manual look at page 15. I'll try to attach it here. Unfortunately the file is to large. You could get 800 watts rms to 1200 watts providing you have 20 amps or more at the wall for each amp in the mono mode. One amp is 392 watts rms 544 watts peak per channel across 4 ohms. I have friends who own 7200 driving 4 ohm and 2,66 ohm loads and the 7200 is a real game changer. But be prepared to add some extra cooling fans if you flash your Power Guard lights to often for long periods. I just wish they had higher signal to noise ratios. What I liked about them in addition to their tight strong bass was the sweet highs. I didn't have the space for all the 7200's I would need so after dragging my heals for 20 more years I have two 207's and a 206. The 207 is the winner here. It can drive 2 ohm loads, too quite successfully, but as I only use 20 to 40 watts at the most for music and push 100 watts to 150 on a rare DVD. I have never had any issues using the amps with electronic crossovers set for tri amping with the crossover at 250, and 9600 hz. The load on the mid/tweeter channels in 8 ohms and the super tweeter loads is 6ohms with the woofer load at 2 ohms. I don't use fans. Even after the Greatest Show man I could comfortably place my hands over all the heat sinks. I always wanted to bi- amp and by the time the 7200 came along, tri'amp. I just didn't have the room and My Crowns were doing OK. But when they were pushing 35 years old and I heard the 207's I knew I had to change in 2008. So I bought my first 207 to supplement my 206 I was using for my bi amped center, rear and side channels. Then I bought the second 207 to replace the 206 and am using the 206 now for remote speakers and electro static head phones. The 207 are now both 10 years old and the 206 12 I believe. Will they last 35 years, hope so. I wish I could. But me reaching 98 seems unlikely.
When I had crowns I used them horizontally so the bass modulations wouldn't influence the HF amps. Crowns didn't havePower guard so if the bass amp started straining it wasn't heard because the mid/tweeter amp and the super tweeter amps stayed clear and pure. I know the idea of using a 207 to strictly drive all the channels of the front speakers seems like a compromise. Well maybe it is compared to using 6 301's . But where would I put 12 301's and 4 MC 152's?. And unfortunately all my speakers prefer direct couple amps with out autoformers. So do I compromise signal to noise and deal with space issues with 10 7200's? No I'll stick with the 207's and 206. Besides if you are not using a MX 151 you are really missing out. It just really out performs my former MX-119 and 120 hands down and makes the 207' really and truly out perform my C-34 with either crowns or 7200's. There is a lot to be said about owning a great pre-amp or processor.
