Dual 3:1 / 6:1 unity gain mixer 2HP

Dual 3:1 audio and cv mixer (up to three buffered inputs with a single buffered output).

Features
• Output of top mixer is normalled to the bottom mixer to give a 6:1 mix
• Outputs are phase correct (e.g. the output audio is not inverted)
• The input signals are neither boosted nor attenuated (unity mixing). their resultant sum is the output, e.g. if input 1: 2v, input 2: 4v, input 3:3v then output1: 9v (input1 + input2 + input3 = 2v + 4v + 3v = 9v)
• NOTE: Version 2 of the Unity Mixer has two sets of jumpers on the main pcb. These allow the top and bottom sum to be set to -6dB attenuation instead of unity gain. This creates more headroom when summing higher amplitude sources like raw VCO signals.

Included
• The module itself
• Eurorack Power Cable
