3-pin versus 4-pin Mini-XLR

Does the compact Mini-XLR/Tini-QG form have three or four conductors? Conductor count does not establish the device wiring or signal role.

How they differ

3-pin Mini-XLR (Switchcraft Tini-QG) connector Confirm the compact Mini-XLR/Tini-QG form and 3-conductor variant; do not substitute it for full-size XLR or infer a wiring scheme from pole count.
4-pin Mini-XLR (Switchcraft Tini-QG) connector Confirm the compact Mini-XLR/Tini-QG form and 4-conductor variant; do not substitute it for full-size XLR or infer a wiring scheme from pole count.
