Bastl Instruments DUDE MK III

Bastl Instruments Dude MKIII is a compact five-channel audio mixer powered by four AA batteries or an AC adapter. Each channel has a mini-jack input and its own mute button, as well as a +20DB gain control for weak signals. As a special feature, Dude can also be used as a tone generator. All you have to do is send the output signal back to the input through passive equalizer or other simple devices. This is possible because the gain of each channel is high enough. The Dude MKIII mixer also has a headphone and line output, which can be used to preview your ideas without a PA.
