Using Aiwa Q Sound Boombox as an Effects Processor
Aiwa Boombox (CA-DW480) has "QSound" onboard. It makes reverb, delays and hard panned sounds seem to appear outside of the speaker box, and bring them forward. This model boombox has RCA inputs (Aux) and headphone (mini jack output). The Qsound processor also affects the headphone jack. That means you can use Qsound as a musical effect! Your sounds and mixes will have a gigantic, impossible soundstage that uses psychoacoustics.
This is a low-fidelity hack, sort of like a bargain plugin. Apparently there are different types of Qsound and encoders. This one says "Virtual Stereo." It is one of the better 3d expansion effects I've heard.
In the early 90s it seems that Madonna and other artists had their music specifically encoded for Qsound. But I'd say the 3d effect works on a lot of content, sort of like Dolby Prologic will, but only with 2 speakers.
I'm not sure they meant for the headphone jack to output Qsound, but this could be useful for someone who likes to experiment. If you find the encoding software you could mix for the Qsound, then "print" the output from the headphone jack. People without QSound should be able to hear what you did.
