Mad Mad Mixer is a 5 channels portable stereo mixer. If you drive it past 3 o`clock it gives a warm analogic saturation per channel to spice up the sounds. Both inputs and output uses 3.5mm stereo jacks. You can feed it with a 9 volts battery (not included) or with a common center negative powerwall like the used in guitar pedals (not included) accepting from 7.5 to 12v. It has protection circuit so if you erroneously use a center positive power wall the unit wont be affected.

It comes in 3 flavours:

• Fully assembled. Ready to plug and play.
• Full kit. Everything you need to build one. You need to solder it. Beginners level.
• PCB alone. You source a few components.
