Analysis

  • Direct termination: No direct connector match between transducer (pentaconn-ear) and device outputs (4-4mm-balanced, 3-5mm-trs). Use a balanced upgrade cable terminated to one of the device outputs.

Cable recommendation

If the transducer ships with a detachable cable (detachable), a balanced upgrade cable terminated to one of the device's outputs (4-4mm-balanced, 3-5mm-trs) gives you the most power and the cleanest signal path. See our balanced cable buyer guide.
