Regarding the volume control settings for the Yamaha speakers: I guess it goes without saying, but the setting of the volume control depends on the level of the incoming signal.
Just to clarify a bit, while the gist of the statement is true, the term “volume control” is actually a tad misleading when folks consider that adjusting the control makes the amp “get louder”. Actually, the amp always provides exactly the same amount of signal amplification at all times. It’s a fixed quantity.
What the “volume control” actually does is to regulate the amount of incoming signal voltage required to drive the amp to the full output of which the speaker is capable exactly as stated in bold above. This is absolutely correct.
But it is helpful to school folks about the difference between a control which controls input sensitivity and a “volume knob (sic)”.
In CK’s situation I’d consider beginning with the 9 o’clock “line” setting and confirm with the recommended observation of the clip light and determining the final, “best” setting from careful trial. But in the end, speakers whose peak SPL capability is less than 120dB are not likely to produce either adequate performance volume or quality when tasked with rock/pop. There’s just no useful dynamic headroom and driving them as hard as is likely will have quite a likelihood of distortion compared to a speaker capable of 6-10dB more output…which will simply be twice as loud.
Actually, the amp always provides exactly the same amount of signal amplification at all times.
may be ok for analog power amplifiers but not necessarily for digital amps.
And from a user's view it doesn't matter at all, since this only affects the internal gain structure of the box.
The user sees an input, an output (air pressure in this case), a knob to control the overall amplification between input and output and possibly some blinking level indicator.
For this discussion, particularly for the MSRs, it would be interesting where this peak/clip lead is internally connected.
If it is connected at the input of the amp (after the pot, fixed gain afterwards), it probably can not determine clipping from sustained power requirements (i.e. playing bass over that PA). A proper clipping detection should check the output swing regarding to the (internal) power rails, which is much more complicated to realize than a simple “volume” detection.
Once again our great guru DR has spoken. Seems he loves to quibble.
Who said anything about the amp “getting louder?” I think you somehow made that concept up yourself in your effort to prove your vast store of technical wizardry. I spoke simply about signal level control, and that is the description given for the knob in question.
Oh, great guru, please tell me this: If I feed a signal into the speaker in question and rotate the level control about which we speak, what happens to the volume of the sound radiating from said speaker? So does that control regulate the sound volume or not?
Please not again… Doc, you know the answer to these questions… hopefully…
I do not understand why it is necessary start a new fight after Dick agreed to your previous post and (correctly) described what technically happens inside the box. We’re all free to simply ignore comments containing too much detail or too common information, others may decide to learn from reading, though.

However, it needs to be directed to DR. He is the one who seems to get his jollies by reading his own views into statements made by others and then taking issue with them. He does it to others besides myself - I’m just one who is outspoken enough to respond to his crazy rebuffs and innuendos.
I regard my remarks to DR as just another form of humor. At least we have added some level of interest to an otherwise dry subject. The kudos need to go to the OP who started this thread. Who would have known that a simple question - Channel or Overall PEQ? - would have generated such wild and wide-ranging verbosity?
Your response regarding an amp always providing the same amount of gain is a good example of how easily one can broaden the context of someone’s statement. I assume you are referring to a VCA, which is one example of an amplifier whose actual gain can be controlled. These things do exist, but that is certainly not the case with regard to the level control on the powered speaker in question. I feel sure that even DR knows about VCAs. I hope he doesn’t take offense.
I’m not talking about VCAs, I’m talking about ClassD amplifiers which, in fact, follow a pretty different approach in making a lightweight signal strong enough to drive a speaker and produce some air movement. “Amplification” in a ClassD amp is a function of scaling the input signal to some sort of PWM, this could be done easily within the digital domain effectively controlling gain inside the amp.
Just thought it could be worth mentioning for someone interested in details, please ignore my post.

If you adjust ANY control between the mic and the speaker…input gain, channel fader, processor make-up gain, main fader, etc, etc, etc…you can effect a change in the ultimate output. Do we call all these things “volume controls”?
I always start by setting all my input channel faders all the way to the top (full on)
then I put the master fader at zero DB and I mix with the gain knobs.
I actually went to evaluate a church recently and saw that. Guy had everything a 0 then just used trims. I was like ‘what?’ He didn’t know any better. Thought that was how you did it.
