This Pro Co Sound Stereo 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. الحالة جديد
