Creating music using hardware has its ups and downs – and any electronic musician knows the horror of not having enough inputs! This audio mixer is a brilliant option for effortlessly blending multiple sound sources. Exciting for any DIY-minded audio engineer, the highly customisable and deceptively simple circuit makes it easy to experiment with your equipment.
Packed into a rugged raw aluminium die-cut casing, this unassuming little device sits quietly in any music studio. Completely passive, requiring no power, its primary function is to combine any six audio inputs into a single output. However – it also has the unusual, and rather appealing, feature of being reversible! This allows it to be used as a one-input six-output mixer, making it an even more versatile studio tool.
Dealing with messy and complicated audio setups is incredibly frustrating, and often large-scale mixers come with a similarly large-scale price! A simple solution is often the most effective, and this mixer is the perfect affordable and easy-to-use answer to your audio mixing needs.

Sound mixers can be daunting devices. With a wide range of knobs and dials, they accomplish audio miracles. Sometimes, though, you just need a simple solution that can achieve similar results.
The master volume adjustment works across the four main channels but does not affect the auxiliary input. The auxiliary input is usable with any mono audio signal up to 4Vpp. The output signal is a mix of the 5 channels transmitted to the tip and ring of a stereo output. You can use a mono or stereo cable on the output.
