Sennheiser MKE 1-4-2

Sennheiser MKE 1-4-2 Ultra-Miniature Omnidirectional Lavalier Microphone (Brown)

The Sennheiser MKE 1-4-2 (Article Number: 502834) is an elite, sub-miniature condenser clip-on lavalier microphone engineered for professional theater productions, musical broadcasts, television studios, and live events. Measuring an incredibly small 3.3 mm (0.13 inches) in capsule diameter, it provides exceptional sound quality and speech intelligibility while remaining completely hidden from audience view.

The "-4" suffix indicates its termination with a specialized 3-pin special connector (LEMO-compatible SE style) optimized for premium wireless bodypacks. The "-2" suffix designates its deep Brown finish, designed to blend natively into dark hair, costumes, and darker skin tones.

Key Acoustic and Structural Attributes

• Sub-Miniature 3.3mm Structural Footprint: Its microscopic size allows sound technicians to hide the capsule cleanly within hairlines, wigs, clothing seams, or directly onto an actor's face without creating intrusive visual shadows or affecting stage lighting.

• 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 energetic 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 hair, 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 clarity.

Defending the Diaphragm During Prep: When styling talent, always slide one of the clear plastic Make-up Protection Caps over the brown capsule tip before spraying hairspray, fixing hair, 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.
