The mixer presented here is derived from the original R2 mixer, with some concession to later designs. It is inverting, and AC coupled, meaning it is for audio use only. A 741 can be used for the op-amp as per the original design, or a more modern op-amp such as the TL071 can be substituted. There are two of these mixers on the PCB.
