Receiver is getting quieter?


Active Member
I've had a HK AVR171 since Oct/Nov last year, since then it has been getting quieter and quieter, normal tv volume used to be around -38, now it's nearer -16. What could be causing it?

Very odd

Have you changed speakers recently? Speakers with lower sensitivity will need to be driven harder to get the same output as those with higher sensitivity.

Otherwise its possible a speaker or set of speakers have become faulty or their crossover units which would result in a change of their impedence and sensitivity characteristics.

Have you switched off the Dynamic Range compression (or whatever HK call it) - when you have that on, it will seem louder- to get it as loud with DRC off you may need to ramp up the volume ?

Did you ever find out the issue? Or does anyone know what is going on?

I am having the same issue. I have a yamaha rx v467 and this is my second yamaha receiver over the past ten years or so. I say this because the volumes on them were identical and I would never push more than -30 for a movie and -40 was my normal watch TV volume. In the past few months it has been getting quieter and quieter, I now have to push -20 to -25 to watch TV.

What is going on?

I didn't want to start a new thread but I will if I have to.
