Right Angle TRS to TS "Stereo To Mono" Converter Patch Cable
This cable sums the tip and ring of the TRS connector to the tip of the TS connector, giving it the name "Mono/Stereo Converter Cable." This cable is designed for use with mono effects within stereo loops. Using the RJM PBC as an example, this cable is meant to connect a mono pedal into loops 7-10 when using them in stereo. You would connect the TS end into the output of the mono pedal and the TRS end into the return of the PBC loop. You will also need to use a Ring Disconnect cable in conjunction with this cable for full stereo functionality with your mono pedal.
