Is this normal?--thump upon powering on

[crouse]

My speakers give out a small thump when I power on my Ma7900. Not loud, but it's there. I know this is normal in my old Marantz 2230 because it is capacitor coupled. Is it normal for the modern Mac?

Is there a power subwoofer connected with the MA7900?

No. Just 2 speakers. They are pretty efficient, but not horn efficient, more like 92db.

Try one speaker or channel at a time so you can identify either L or R or both

Small thump is normal on the integrated amps.

Thanks,

I did own Rotel receiver and my memory did not recall the small thump from the speaker when power on.

My MC2205 amp will thump on power up. Nothing drastic, just there.

No muting relay in Mc integrated amplifiers? Wow.

Should not thump at all if you power ON the MC2205 Last and OFF First

I own an MA7000 integrated and it definitely has a muting relay. No thump whatsoever.

No thump from my 2200s, even before the re cap.

Tell that to Ron.

I had a C48 / MC202 combo that made no sound at all that I could hear from the speakers when powered up. Now I have an MA7000 and it doesn't make a thump but it does make a sort of click sound from the speakers when powered on. The sound is rather like having a microphone next to the power button and the actual mechanical sound of pressing the button is amplified through the speakers. Weird and a little concerning.

Thanks Ron. That's a relief.

That is normal! No problem! Enjoy your MA7900!

No thump with my MAC6700 integrated.
