What Ant said - I use my receiver for 5.1 and for stereo. It's an old amp now, and has a button on the front to force whatever you're putting through it into stereo. Might be best to download the manual from the manufacturer's site if they do one and check from there...
I have the Onkyo HT-R393, it has a different menu set-up to Ant's, but does exactly the same thing in letting you choose which speakers are attached to it. Until recently I only had front left and right connected, due to moving and being too lazy to run speaker cable where I needed it, and had the amp set to 2.1 without having to change any of the source audio.
Perfect! Thanks (and to graph and matt).
So onkyo are OK then? Sounds like a brand of yoghurt, as long as music doesn't sound like it's got added Fraudulide R then I'll be happy.
I did find the manual earlier to find out about pass through when the amp is off. Didn't think to look up down mixing :$
Onkyo seem pretty popular and I remember when I was looking fairly priced. No issues with mine. Got a reasonable deal on it a few years ago. Never actually bought a decent speaker setup though.
Cool. I'll decide if I can face spending the money next week.
Onkyo was and is a good brand, I wish I had purchased their 6 disc CD player years ago.
6 discs at once? That'd sound horrible.
Damnit, I'm sure that amp was £150 when I looked at it originally. £180 now :(
