The One Series Neuro Couplers provide a robust and efficient connection between side-by-side One Series pedals. This pair includes one 1/4" mono (TS) connector and one 1/4" stereo (TRS) connector. The TRS/TS connections makes it possible to simultaneously send Neuro Mobile App messages and stereo audio signals to an entire chain of One Series pedals.
Simply use the TS connector with Input/Output 1 of the pedal pair and the TRS connector with Input/Output 2. The Neuro Cable (included with every One Series pedal) connects from the headphone jack of a mobile device to Input 2 on the first One Series pedal in the signal chain.
