The Circuit Slices CS030 module is a quality, low-noise, audio and CV mixer for the Eurorack synthesizer format sold at an affordable price.  Features five audio or CV inputs, plus one more input without attenuation, mixed to one synth-level output and one line-level output.  With an LED to indicate the output level.  Also includes selectable linear or audio type response for each control. 

Circuit slices is known for quality builds at very affordable prices -- here is another!  

Specifications for theCS030 Mixer
