#Sennheiser MZH 3015 L Gooseneck, Matte Black, 150 mm, XLR-5

Sennheiser MZH 3015 L Professional Metal Gooseneck (Matte Black)

The Sennheiser MZH 3015 L (Article Number: 009435) is an architectural-grade, ultra-compact metal gooseneck arm engineered for high-end permanent installations. Measuring exactly 150 mm (5.9 inches) in length, this specialized low-profile stem provides a sleek mounting option for Sennheiser's premier IS-series modular microphone heads (the ME 34 cardioid, ME 35 supercardioid, and ME 36 mini-shotgun). It is widely deployed in council chambers, broadcast desks, courthouse podiums, and premium corporate boardrooms where minimal visual distraction is paramount.

The "-L" designation specifies that this gooseneck features an integrated red LED status light ring at its collar paired with a 5-pin XLR-Male base connection.

Key Structural and Engineering Attributes

• Integrated LED Status Light Ring: Features a clear, high-visibility light pipe wrapped around the upper neck assembly just below the capsule head threads. When integrated into a control network, it glows solid red to visually indicate to speakers or broadcast hosts that their microphone line is live.

• Premium 5-Pin XLR Configuration: Engineered with a specialized 5-pin XLR layout. This separation allows the balanced analog audio signal and standard 48V phantom power to travel cleanly down pins 1, 2, and 3, while pins 4 and 5 are completely isolated to handle the independent DC power supply loop needed to control the LED ring.

• Advanced Shielding Against RFI: Outfitted with Sennheiser's updated, high-density internal RF shielding matrix. This design suppresses electromagnetic and intermodulation interference caused by close-proximity smartphones, Wi-Fi routers, and wireless production communication headsets.

• Precision Mechanical Articulation: Built from a rugged steel-core alloy with a single, ultra-quiet flexible section at the lower portion of the shaft. This allows for smooth, squeak-free position calibration that stays locked over long meetings without slipping or sagging.

• Stage-Ready Matte Finish: Coated in a highly durable, specialized anti-reflective matte black protective finish that completely suppresses camera glare and harsh overhead studio lighting reflections.

System Architecture and Interface Advice

Pairing with Surface Receptacles: Because this gooseneck terminates in a 5-pin male XLR array, it cannot be dropped into standard 3-pin mic jacks. For clean, flush-mount desktop integration, it must be paired with a dedicated 5-pin female receiver base such as the Sennheiser MZT 30 L table installation socket or the MZS 31 shock mount. This keeps the independent control voltage lines separated from the primary audio feed all the way through the table surface.

Managing Logic Control Switching: The integrated red light ring requires a separate external direct current power supply ranging between 9V and 30V DC to illuminate. It is intentionally decoupled from the microphone's primary 48V phantom power supply line. To enable functional push-to-talk automation or automatic mixing gating, route pins 4 and 5 of the cable infrastructure through a logic-controlled relay switch or a programmable DSP unit (like a Biamp, Q-SYS, or Symetrix controller) to connect or break the DC loop based on mic status.
