Also in some issue of _Radio-Electronics_ they describe a quick hack to get surround sound: just grab a third speaker and connect it to the positive speaker terminals for both the left and right channel. It would look like this: __________________ | | | Surround Speaker | |__________________| | |_______ ________|_________________|____________________________________ | | | | | ___|______ ___|______ | | | | | | | | | | | + O O - | L R | + O O - | Amplifier | | |___|__|___| |___|__|___| | | | | | | | |________|__|______________|__|_________________________________| | | | | ____|__|____ ____|__|____ | | | | | Left Spkr. | | Right Spkr.| |____________| |____________| I haven't tried it, mainly because I don't have a stereo to try it with. :-( You want to be careful with speaker impedances, but if you have a third speaker lying around, you ought to be able to get surround sound dirt-cheap. ------------------------------------------------------------------------------- Scott Alfter _/_ / v \ Apple II: Internet: alfter@uns-helios.nevada.edu ( ( the power to be your best!
