    Just have a few question for TC electronic RH750 owners who paired up a single RS112 speaker on this amp. If you have done so..

    Did you have any problem with this set up? Knowing the fact that the RS112 speaker is only rated at 200w. To combine it with RH750 Amp that produces 750w?

    I’ve seen one video with this set up on youtube. I like the fact that it’s great set up for portability but my main concern is would it give me any problem in the long run?

    Will the Amp gets hot running this set up or blow up the speaker overpowering the speaker. things like that?

    Do a search of RH750 power rating. It's only 235 watts!

    Yep, it's 236 watts RMS. It is definitely freaking loud with TC's Advanced Power Management technology, but that cab should be safe. Although it still is only a 1 12 cab so don't expect crazy volume.

    RH750 has 750w from what i understand. At least that’s what they said about this amp. My understanding is that if you run 8ohms cab, the amp only produce half of its full power. So 375watt. But still that’s overpowering the RS112 speaker which only rated at 200w.

    I have not seen anyone mention that this amp only has 235watt power...may be i’m not searching hard enough. If it is so that this amp only has 235w then TC electronic would be fooling their customers by stamping a 750 on their amp that’s not!

    I so assume you have tested this set up already. So the amp does not get hot or anything and the speaker can handle it?

    Start reading around post 312.
    TC Electronic RH450, RS210, RS212 Review Thread (Part VI)

    I personally love the RH450/750 and am amazed at what they can do and and have owned them for the past 5 years. I just hope this doesn't become a dog fight again like it did in 2011. Old news.

    I have found one source where this guy mentioned that the RH450 is only rated at 235watts But he was referring to RH450 and Not the RH750.

    They are the same wattage. This subject has been discussed to death on this board.

    Wow! Didn’t expect that!
     
  10. TC uses some management tech on thier power sections. Most likely its main focus is to expand life spans. But either way, they do get loud, sound great, and have nice features to boot. I've been well more than happy with the ones I've owned and tried.

  11. Loud amps for sure!

    But at the expense of the raw slammin’ low end that one would expect from 750 watts. Highly attenuated low end and a butt load of compression.

    However I would say that the rh line has a beautiful midrange voicing that I haven’t heard anywhere else.

    The rh line is designed to drive 3 rh cabs.

    Don’t worry about the Watts.

    This nonsense is getting old.

    The TC amps are as loud as they claim, no matter what's under the hood.

    Thank you all for your response!

    I believe TC is done with RH the last update for this line up was the RH750. No update or newer release after this model.

    Do you guys think the TC RH amps are still good amp today? I’ve always wanted this when it was first released but could not afford it then. Didn’t want to drop $1000 for the Rh750 back then. As time goes new technology better amps arises. Do you guys think RH amp still compete today and is still a good amp today?

    To answer your question, yes, it works just fine. As others have said, don't worry about the watts (power management or not) rather pay attention to the ohm load. RH750 can run either an 8ohm or 4 ohm load (or 2 ohm load provided you're running TC Cabs) and as the RS112 is an 8ohm cab, you won't run into any usage issues unless you turn it up too loud and overpower the single speaker. Fortunately, your ears will tell you if that's happening as the cab will be farting out like crazy if you're driving too much volume.

    I've run an RH750 with a myriad of different cab combos over the last 5 years (from single RS112 all the way up to a 2xRS210+RS212 stack) and the key is to listen to the cab. A single RS112 isn't going to get overpoweringly loud but it will handle the RH750 just fine on it's own.

    A definitive "yes" from me. But I'm biased plus the brouhaha over the watts dropped their value making the line an incredibly affordable, fully featured, amp/cab series that is STILL yet to be matched by anything else out there IMHO. A crazy-good built in Spectracomp compressor, Tubetone, 4-band semi-parametric EQ, 3 presets, an effects loop, super clean DI, digital out, tweetertone, and, as others have mentioned, it gets crazy loud with those 236 watts that turned many others off to the head. I've played many different heads from GK, Genzler, Ampeg, others, and dollar for dollar, they don't compare when you look at all the built-in features.

    I owned an RH750. It's a good amp. While it actually is 236 watts, it is much louder than one would expect - more like the 750 watts they advertise. The biggest problem with them, and the main reason I sold it, is that the knobs are ridiculously fragile. I replaced mine twice before I sold it.

    Yes they definitely still can and do compete with todays amps. It is still one of my favorites right up there with the Genz Benz Streamliner 600 and the newer Orange Terror Bass 500. I gigged last night with my Genzler Magellan 800 and the RH750 can hold its own quite well with it. IMHO and IME.
     
  18. The only thing that turns me off about the RS series cabs, is that one of the speakers is a coaxial. One woofer, one 2 way speaker. I just dont see each speaker performing in the same way. In my mind, that's a design problem. That's why I went with the K series cabs instead.

  19. Yes they are fantastic amps with a great feature set! The voicing is like a modern take on vintage/old-school tube tone. The spectracomp is nice, and the tubetone is very realistic IMO.



    I am a little perplexed as to why they havent been revised over the past decade (being digital the possibilities are endless), but they are great amps for sure.

    Nope, not a design flaw at all. Both are 10 inch custom eminence drivers with one being dual concentric meaning that there is a 1" titanium diaphragm tweeter with a 1.5" aluminum coil hidden underneath the dust cap of the top speaker. It works very well and saves space although the K series cabs are also very nice. I own 2 RS210's and 2 K212's and am quite happy with both. :cool:
