is lower volume less consumption

[mantalic]

I have a 500w Panasonic home cinema audio but I don't know how much power consumption it takes, will it take less power consumption if I set the volume to 10% rather than a 100% if yes how much

they make power meters for this. you plug your device right into it and it tells you the wattage used. go to home depot and pick one up.

Yes you will be pulling less power from the socket. Is there any purpose to your question other than electrical savings? In order to find out how much you would need to use something like this:

500W is the max output. There is no way to know how much power it will use as an input without the access to the wiring diagrams or measuring it. Yes lower volume should use less power but that's not really relevant. It uses what it uses

If you want to know power usage for an appliance just get one of these.

as stated above, you want to get yourself a power meter for this.
