Well my units have finally arrived(RC-1070, RB-1080). Hooked them up to a pair of RTI-12s. And it really sounds good. I was expecting the 1080 to have a little more growl than it does. I don't think that it's so much the amp than the speakers. I have four bose 301's that I use mostly for tv. I got to thinking I wonder if a 301 can hang with the 1080, so I hooked up a pair of them in the back and left the polk rt 12s in the front hooked up. WOW to my amazement the 301 can hang very well with this amp. It sounds much better running the 12s and 301s together than just fronts. Also the amp did sound very bright and shallow at first but now that it's starting to break in or "cook in" it is starting to sound much better. Does anyone see any problems with this configuration(speakers). The Bose are only rated for 150w but they sound like they are up to the job. Also another question I have is when you use all four post in the back of amp does this "split the power" 200w divided into four would be 50w per speaker ? 8)

So you have all four speakers running off the 1080?
That's not that great of an idea, you are really going to be pushing that amp when some of the impedence really drops down. Eventually I wouldn't be surprised if you fry it at some point. Like if you turn it up loud.
Also, why are you listening to a stereo signal with 4 (ala quadraphonic) speakers... You'd still much better imaging with just a single set of speakers...
The polk should do good, you just need to let the 1080 work itself in. You will notice that you don't get the "booming" bass from them because that's not how the sound was really recorded. You should notice a tighter, quicker bass from your speakers, just not overwhelming bass like you were used to because it wasn't reproducing accurately.Digital Audio makes me Happy.

Thanks for response Pewter. I did notice that it was running a little hot( still be touch with hand on top) with vol. knob at about 12 oclock postion. But I'm uses to amps running a little hot....right? Also another thing that got me thinking is why ROTEL would put four speaker post on back if this created an unsafe condtion for it. Wouldn't this be designing the amp to fail? As far as runnning four instead of just two....I don't know. The music just sounds fuller. Again thanks for responseComment

The extra posts on 1080 are for bi-amping your speakers.Comment

thanks dinnuComment

lucky you AMPER....in my language "AMPER" means "almost"....you almost cooked your amp...it would have been disasterous. I have a RB1070 and it seldomly gets hot driving 200W speakers at the 10 to 10 vol position...I can only imagine that the 1080 will stay much cooler at higher volumes...impedance would have killed the 1080...Regards :T,

what threw me off was that in my owners manual it only shows the right and left side, total of four post. But the amp has eight. I don't understand why they haven't update their tech data. Also does it matter if I use top or bottom terminals?Comment

G'day,
I've currently got an RMB-1095 5x200w amp, about 2 weeks old. For a few hundred dollars, I can trade this in to get 3 x RB-1080 2x200w amps.
I'm wondering about the advantages and disadvantages of such a move.
This is what I've come up with:

I hooked up my Rotel RB 1080 last night to my Monitor 11's and it has a hum coming through the speakers. My RMB 1075 only made a hum when the amp was on and the reciever was off but the RB 1080 makes a hum when the reciever is on and I can here it when the volume is low. How do I get rid of it I read... -
Finally decided on my speakers B&W 803 fronts, HTM 2 center and cheapo 600's for my side and rear surrounds (ran out of money he he he).
Now the question- (I think i brought this up before and Andrew kinda answered it but i lost that thread.)
1) B&W recommend bi-amping... -
My RB-1080 looks different. It has the Lucas THX Ultra logo on the front and the back has two pairs of binding posts, (four posts for each channel). Does this seem right to anyone?
The logo was a big surprise. Even the picture on Rotel's web site doesn't have this. And I wasn't expecting... -
I added one of these today to my HT. I had a Pioneer that was built for Radio Shack, still have it. But was always disappointed with the sound.
I think this changer has changed my mind about changers just from the first listen anyway.
I wanted to test it out tonight, since...
