Synthrotek is proud to offer a line of 1U Eurorack powered modules for your modular synthesizer system. 20 and 24HP sized modules means that you can completely fill a 84 or 104 HP row with no extra modules or blank panels needed.  Synthrotek’s waterproof cases come with a 1U row designed for utility, performance and beyond! Available as a complete factory assembled module, a kit and PCB/Panel combo.

The 1U Unity Gain Mixer adds input signals together and combines them for a summed output. For example, if you put in a 1V source and a 3V source, the output will be 4V. It’s mainly used for CV, but it can also be used to combine audio signals together.

A unity gain mixer is handy in several ways:

• Combining gates and triggers. Plug a few sequencer steps into the unity gain inputs, then run the output to a drum synth, VCA, envelope, etc.
• Re-shaping two CV sources with a single envelope.
• Combining different wave shapes or LFOs to make crazy sounds.
• Controlling the CV of one source with the CV of another source. Just plug the CV out of a sequencer into and an expression pedal/touchable CV out into the unity gain inputs.

Features:

• 2 channels, 4 inputs per channel
• Mixes both AC signals (audio) and DC signals (gates, triggers, CV)
• Input signals are not boosted or cut
• Sum of inputs is the total output
• Channel A is not normalled to channel B
• Polarity protected
