RF83/64 amp question

Recommended Posts

Can I utilize this amp: Rotel RB956AX, along side onkyo sr806? It will essentially be free. I was thinking of using it for my center and surrounds once I get them and strickly using the receiver to run my fronts. Any thoughts ?

Sure you can.

Since this Rotel has plenty of flexibility, it can be configured in many different combinations. Try using it to run your center and surrounds and then try it as just a stereo amp driving your left and right fronts. Demo each configuration with complex music and action heavy movies with heavy mid/high bass punch. You then should know if you hear any benefits to adding the Rotel or not. Definitely worth experimenting if the amp is near free to you.

Won't hurt to try for free but I just looked up the specs at 30 watts rms per channel? If that's right I don't think you'll benefit at all. Best thing I could think to do if you already own it is to run your four surrounds off of it and let your receiver just run your front three.

The RC 64 needs as much power as the RF 83 and 100 watts may not carry you thru the peaks. Surround duty is not bad and leave the amp for the from 3.

Derrick the amp is only 30 watts per channel rms.

That is extremely low wattage for HT use.

I agree to many peaks in movies imo for 30 watts. Imo you would be turning it up and down the whole movie.

My concern is clipping the amp and damaging a speaker! It does not take more than a few seconds to do.

I would bridge it together and use it as a 3 channel more than likely. That would give me 90 w per channel.

well like we all said. cant hurt to try. try it both ways. try for LCR and surrounds on receiver then try it with the four surrounds and then LCR on receiver. 90 isn't alot still for the 83/64 combo. id look for a used xpa-3. ive seen em for like 450$

Are you running 5.1 or 7.1? If 5.1, I believe your Onkyo will likely provide better power to your 5 speakers than by adding the 30 w RMS amp to the mix. I had an Onkyo 703 and a Yamaha RX-V1800 and both had no problem driving my 5.1 RF-83 system. Adding a 220 x 5 amp made a difference in added clarity, added bass (even at low volume), plenty of headroom, and the ability to reach reference levels without strain.

Just keep in mind when you biamp the three channels to get 100 watts/ch, you are increasing the amount of distortion into your system.

It looks like you received it and assume everything made it in tact. I hope you're happy with it.

Also know that you can "bi-amp" the front speakers with the rear channels if you're only using 5.1. I don't know how much that really helps but I assume it would give you a little more headroom.
