This Pro Co Sound Stereo 1/4" Male to 2 XLR (1 Male, 1 Female) Y-Cable is an insert patch cable that allows a mixing console to send/return signals to an outboard effect processor. The cable is wired as follows: ring on the TRS to pin 2 on the female XLR and tip on the TRS to pin 2 on the male XLR. Pins 1 and 3 are bridged on the XLRs. These are rarely used today, only when the processor uses unbalanced XLR I/Os.
