Am I reaching the max power / amplitude of my Rotel RB-951 power amp?

thatguyyouknow

I am only able to get up to a maximum of 70 decibels with the meter in between the speakers. The clipping indicator on the amp does not come on at any point. Since I seem to have such a distinct cutoff in volume, regardless of the input method, I'm thinking that I must be reaching the power limit of my amplifier. Does that sound right?

No. It sounds like your source has insufficient level to drive your amplifier to full output.

Hey, thanks for the response. So I’ve tried two different sources. One, bluetooth into the eskinsin receiver which is plugged directly into the amp.

Two, playing the tuner in the kenwood stereo receiver, plugged directly into the amp through the kenwood's pre-out.

So you think both of these sources have an insufficient level to drive the amplifier?

your speakers are 5ohm, 88db not overly sensitive but not bad either your amp has 150wpc so i would not expect it to run out of power. I suspect something else is the issue. Like Cleeds mentioned it may be not enough gain in the preamp/source. The kenwoods pre-out may not be up to the task. Or another issue that's not easily determined from the information available. Like is muting on. 

One thought though your meter is between your speakers? is this directly between them as that's not the ideal place to measure from. 

I’d love to say I’ll just keep tinkering with it, but i’ve been tinkering with the problem off and on for the better part of 6 months now. The only thing I have left at this point is to start buying other alternatives and switching things out, unless anyone has any suggestions with the equipment I already have.

You’re right, it’s not the best place to measure. It happens because I’m sitting on the ground with the units pulled out to mess with them so that’s where I’ve been measuring from. I’ll take an accurate measurement this evening to see where I’m actually at, but regardless of the number my volume is still limited to below where I would like to be able to listen to it at times.

Thanks for taking the time to help. This issue has frustrated me for a while and I just want to sit down and enjoy my set up haha. Sorry if I come off as frustrated.
