Example Installation / Usage Scenario
Suppose you’re fabricating a custom audio interface box for live performance or a studio patch bay. You install the NC3MD‑L‑1 onto the front face of a steel rack panel with the standard D-shaped cut-out. From the rear, you solder XLR cable or internal wiring (e.g. to a transformer, preamp, or internal signal bus). Because of the well-shielded metal shell and coaxial ground contact design, the assembly helps preserve signal integrity and minimize interference—especially when mated with Neutrik XLR cables or connectors in the D-series family.
For example, using it as an input connection on a rack-mounted DI box or a distribution box ensures secure locking, solid contact, and longevity through repeated cable insertions/removals.
Tips for Use & Best Practices
-
Use a high-quality soldering iron with appropriate tip and good technique; avoid excessive heat that could damage the plastic insert.
-
Pre-tin wires and the solder cups before final soldering to improve consistency.
-
Be careful with strain relief: ensure the cable or internal wiring is secured so mechanical stresses aren’t transferred to the solder joints.
-
Use matching D-series mating XLR connectors (Neutrik or compatible) to maintain proper shell contact and shielding.
-
If you need a black-housing or gold-contact variant, consider models like NC3MD‑L‑BAG‑1 (black shell, silver contacts) or NC3MD‑L‑B‑1 (black shell, gold contacts).
