The Blood Cells Audio 221.X2 is a 10HP, expandable, 4 channel audio and cv utility module that is equally at home mixing Control Voltage as it is audio.
Two independent 2-to-1 mixers offer per-channel attenuation and inversion, as well as +6dB of gain available at the summed outputs. With a tap of the "All Mix" button, these separate mixes can be combined into a 4-to-1 mix at the "All Mix" output - meanwhile, the first 1+2 mix is still available at its respective summed output. A rear expansion input and output allows for combining multiple modules into larger systems.
Each channel also offers a Direct Output that can be taken pre or post attenuation / inversion.
A 6-volt offset is normalled into the input jacks of channels 2 and 4. This voltage is available at the channel's Direct Output, as well as added to the mixed outputs. Useful as an offset for mixing with another CV signal, or simply as a voltage source.
Each summed output group has two blue LEDs for displaying the shape of the summed CV, and can also serve as signal present indicators for audio. Peak LEDs trigger at ~9.6V, allowing for a bit of headroom before things get out of hand.
