English copy

XLR and TRS can both be used in balanced audio systems when the wiring and equipment are designed accordingly. The connector type should be selected around the system architecture, not brand preference.

XLR connectors are common in microphones, stage equipment, and professional audio interfaces where locking or robust cable connection is valuable. TRS connectors are compact and common in patch bays, mixers, instruments, and line-level equipment.

Review pin assignment, locking or retention, panel space, cable strain relief, mating life, shielding, contact plating, and assembly method. Verify the complete signal path to avoid noise or phase problems.
