General Description

The Shure DuraPlex DL4 is a professional MEMS condenser lavalier microphone that is ideal for both speech and performance applications in challenging environments. The IP57 rated omnidirectional lavalier is dust resistant and waterproof, manufactured for use in applications that require extended durability, uncompromised sound quality, and reliability. The subminiature design and various mounting options provide discrete placement in applications for film, television, education, and corporate events. Each microphone is supplied with a storage pouch, single tie clip, sticky vocal presence frequency response cap, snap fit windscreen, foam windscreen, and TA4F threaded adapter.

Features

  • IP57 Certified dust resistant and waterproof/sweatproof headset
  • 5mm omnidirectional subminiature design for discrete placement and improved gain before feedback
  • 1.6mm PLEX Cable technology, paintable cable, and no memory effect
  • Professional sound quality for speech and performance applications
  • High RF immunity, compatible with digital wireless systems without RF interference
  • Attachable Presence Cap included for tailored frequency response in speech applications
  • Included furnished accessories for storage, mounting options, and wind protection
  • TA4F and LEMO terminations for variable wireless system connectivity
  • Included sticky mount (adhesive patch sold separately) for application requiring placement underneath clothing
  • Available in Black, Tan, Cocoa finishes

Care and Maintenance

The DuraPlex omnidirectional microphone has been IP57 dust-protected, waterproof rated by extensive internal tests, so you can clean it using distilled water and a mild detergent when necessary.

Attaching the Windscreen

There are two windscreens for use with the DuraPlex microphone:

  1. A slide-fit windscreen for use with the presence cap

  2. A snap-fit windscreen for use without the presence cap

    Note: Do not use the snap-fit windscreen with the presence cap--the presence cap can become caught inside the snap-fit windscreen.

Specifications 

Note:

  • All specification values are based on using a typical bodypack with 5 V bias input or the RPM400MTQG preamplifier. When using the RPM400LEMO amplifier, refer to the RPM400LEMO specifications.
  • All specifications measured with a 48 Vdc phantom power supply. The microphone operates at lower voltages, but with slightly decreased headroom and sensitivity.
