Volume Adjustment

Not an engineer. Wonder if there is a simple answer to why volume setting 53 on my MA-252 seems so much louder than 52? Speakers are Sf Olympics llls. 

It’s certainly not 1 decibel ?  Is it logarithmic or something I won’t understand ?

Are there amps that have just 1 decibel increases? 

When I listen at setting 52 and want the sound just a little bit louder, setting 53 seems too loud ?

Answers and thoughts appreciated. Thank you.

Hello @teboerio 

This is an interesting discussion. Thanks for sharing. 

My rule of thumb for loudness is: 

+3 dB = doubles the acoustic power, but sounds only slightly louder.

+10 dB = sounds about twice as loud to most listeners.

+20 dB = sounds about 4× as loud.

+30 dB = sounds about 8× as loud.

Regarding the MA-252, I am not exactly sure why that is. I would ask the manufacturer for details. You can share my reference with them, and their engineers can get back to you about exactly how much louder they intended it be/sound  past 52.

Good luck with this.

That’s strange 1 click would make that much difference. What about 51 to 52, is it a similar increase in volume?

From your description it seems that there is something amiss with the volume control. There should not be such a big difference with a 1 decibel change!

something is wrong. measure with an spl meter to document the change, then give McIntosh the facts.

you can buy an inexpensive one (with a bottom hole for a tripod), it's good to have one
