Stoweblank TinyMix

The TinyMix is a device which allows you to connect up to four audio sources to a single set of amplified speakers or line output, using sophisticated electronics to provide the highest quality sound. Powered by USB, the TinyMix can be plugged into a computer, a powered hub, or into a USB voltage adapter. An LED indicator lights to show that it's powered on. When powered off, the TinyMix will operate in passive mode, which draws its operating power from the audio inputs themselves, at a cost of reduced volume. If you've ever tried just using a Y-cable, you know why it can be a bad idea -- it can drive audio from one device to another, which is why the volume will change when you turn one of the devices on and off. This can cause clicking, popping, and humming -- and worse, it's possible for your audio devices to damage each other or your speakers. Audio signal voltages get added together by Y-cables, which can boost levels high enough to cause distortion or damage. As the graph illustrates, this may be fine for a while, until the peaks of the waves align, and this can boost voltages above levels that are safe for your devices. The TinyMix normalizes, combines, and outputs audio signals, which allows multiple audio signals to play simultaneously without clipping and distortion. Plug in up to four audio devices, and plug the TinyMix output into a set of amplified speakers or stereo inputs. Devices can be plugged in or unplugged as desired, without worrying about volume levels changing dramatically or clicks, pops or hums.
