Sennheiser MKE 1-4-1

Sennheiser MKE 1-4-1 Ultra-Miniature Omnidirectional Lavalier Microphone (White)

The Sennheiser MKE 1-4-1 (Article Number: 502833) is an elite, sub-miniature condenser clip-on lavalier microphone engineered for professional theater productions, musical broadcasts, houses of worship, and live television. Measuring an incredibly small 3.3 mm (0.13 inches) in capsule diameter, it delivers outstanding speech intelligibility and natural vocal weight while remaining visually unobtrusive.

The "-4" suffix specifies its termination with a specialized 3-pin special connector (LEMO-compatible SE style) optimized for premium wireless bodypacks. The "-1" suffix designates its clean White finish, designed to blend natively into white shirts, wedding dresses, light liturgical vestments, or for clean placement inside blonde hairlines.

Key Acoustic and Structural Attributes

• Sub-Miniature 3.3mm Structural Footprint: Its microscopic sizing allows sound technicians to hide the capsule cleanly within costumes, collars, or hairlines without creating visual shadows under bright stage or television studio lights.

• Sweat-Defying Protective Matrix: Features a multi-layered acoustic defense system consisting of a specialized protective membrane and an ultra-fine stainless steel mesh gauze. This combination guards the internal electret element from moisture, humidity, and stage sweat, preventing acoustic "sweat-outs" during high-intensity live performances.

• Heavy-Duty Kevlar™-Reinforced Cable: Built with a thin 1 mm diameter cable core-reinforced with genuine Kevlar™ strands. It delivers high tensile strength and features a molded anti-kink sleeve that isolates structural handling and friction noise from entering the audio stream.

• Extreme Sound Pressure Resilience: Specially tuned to manage high dynamic peaks. The capsule captures vocal shouting, intense dramatic dialogue, and booming theatrical delivery up to 142 dB SPL cleanly without clipping or audio distortion.

Field Configuration and Care Advice

Acoustic Equalization via End Caps: Because this microphone is typically concealed behind costume fabric or buried beneath layers of wardrobe, natural acoustic damping will soften your high-frequency detail. To fix this, clip on either the MZC 1-1 small cap or the MZC 1-2 large cap. These physical caps change the acoustic impedance over the diaphragm, providing a targeted presence boost of up to 5 dB in the upper registers to preserve speech clarity.

Defending the Diaphragm During Prep: When styling talent, always slide one of the clear plastic Make-up Protection Caps over the white capsule tip before spraying hairspray, fixing wardrobe, or applying powder foundation. Aerosolized products can coat the ultra-fine inner protective gauze, causing permanent frequency loss or destroying the capsule membrane entirely. Once the talent is dressed and ready to take the stage, swap the protective cap for your chosen acoustic frequency cap.
