SOURCE: buzzing emitted by vsx-409
Could be the result of having DTS compatible equipment connected through the analog inputs on the VSX-409D. Noise and distortion will result as essentially the DTS signal is being played back undecoded. If this is the case you'll have to connect your LD or CD player through the digital connections (coax or optical) and set 'Signal Select' (button on front) to 'Digital'.

You could buy a universal remote control and try the following NAD audio remote codes to program it with:
575 773 975
I read somewhere else that the 'Supplied Code for NAD receivers' was 033, but cannot confirm this. Try the first 3 first.
Universal remotes tend to be pretty cheap, certainly cheaper than buying one from NAD.

Love your screen name.
You didn't say what, if anything, preceded the appearance of the problem. There might be a clue.
Can you describe the distortion? Is it excessively bassy? If so, is it happening on all sources?
I'm assuming this is a modern digital receiver that is capable of many soundfield simulations as well as native Dolby Digital, DTS, multi-channel. If so we can use a stereo source and through simulation redirect some of it to the center speaker.
Using one of your receiver's many multi-channel simulation modes, put in a CD or tune an FM station and use it to diagnose the problem during later steps.
If it's only a single source and that source uses individual analog channel RCA cables, swap in another one or temporarily move the Center Channel feed to one of the other channels to see if it's before the receiver (in the source).or inside the receiver.
For multiple sources:
Is your Center speaker defined properly as Large or Small in the receiver's setup menu?The size refers mostly to the bass-handling capacities of all your speakers rather than their physical size. Speakers designated as 'Small' will not be sent much in the way of bass because they can't handle it well. The LFE/subwoofer channel(s) will get all the bass that was intended for them instead.
If you have a Small speaker improperly defined as Large it may be getting bass that it can't handle and that might sound like distortion. Having a Large speaker defiend as Small would result in less bass than expected but otherwise 'clean' sound.
Check the speaker setup in the menu for excessive volume level relative to the others. There is usually a calibration procedure the receiver will use to help you adjust the subjective voume of each speaker using white noise or tones.
Hope this helps.
