Ive recently setup a new Onkyo txnr616,ive got good quality speakers and speaker cable, my only gripe is that the sound is low,it only starts getting decent sound at about level 65,surely it should be very loud at about 30, any suggestions would be helpful.

All sources or just one? Does whatever you have connected to the amp have it's own volume control that could be turned down? Have you checked the IntelliVol settings for the inputs?

Also make sure the Dynamic Volume is set to OFF. I would also turn off the Dynamic EQ and all the other fancy Audyssey stuff. In my experience they just knacker the sound. Though dynamic volume can come in handy for some Blu-Ray sound tracks but using it with TV sound for example I've found it largely unnecessary.

On my 507 a volume setting of 30 is pretty quiet, I usually run it at 40 or so. And that is not particularly loud either.

30 what? What is the max it goes to?

it seems quiet on all inputs, iam running a sky + hd thru it at mo.by 30 i mean volume level

Of course "quiet" is a subjective term. Some people might think standing 2 feet from the PA stack at a Motorhead concert is quiet while others would consider a pin dropping on carpet three miles away deafening

30dB? That would be quiet.

Volume isn't linear, and neither is the volume control. It's logarithmic. That's a fancy way of describing how the volume reacts to each incremental turn of the volume knob. Volume commonly doubles on the previous level: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512. If you were to plot this out on a graph then you'd see a ski jump shape; fairly flat at the bottom but then increasing in slope until it goes vertical.

It's totally normal for a home cinema amp to be pretty quiet for almost half of the volume control range.

This is why I prefer my volume controls to have no markings.
