Professional Lavalier Wireless Microphone System

wireless lavalier lapel microphonewireless lavalier lapel microphone

The key words here for Fifine K037 lapel mic are light, compact, portable, wireless, dependable performance with common audio equipment.

  1. Includes everything you need for a microphone system in a compact box. One lav mic, transmitter, receiver, windscreen and a 1/4'' to 3.5mm TRS adapter.
  2. More reliable signal in UHF (Ultra-High-Frequency) band. The valid distance is around 50 feet (15m).
  3. There are 20 adjustable frequencies and could be transformed easily. No worry about frequency interference.
  4. High-quality microphone capsule greatly minimizes noise and makes your voice clear.
  5. Easy to operate, with backlit LCD screen on transmitter to show the working status.
  6. Solved your need for a wireless clip on mic.

Note: The mic is designed to be used with speakers or audio devices with 6.35mm mic jack. We don't recommend to use it with cellphones, computers, tablets and Apple products.

Easy to set up and operate with your speaker or other audio devices.

Step 1
Plug the mini XLR lav mic into the mic jack of the transmitter.
Step 2
Turn down the mic volume on the speaker. (Speaker is not included in this model, Fifine K037.)
Step 3
Plug the receiver into the 1/4'' (6.35mm) mic jack of the speaker. (Make sure the receiver is “off” when you do this.)
Step 4
Turn on the transmitter and then the receiver. They will pair with each other automatically. Indicator on the receiver will turn red when paired successfully.
Step 5
Slightly adjust the output volume on the speaker until you get the best effect.

  • Higher coverage will likely result in quicker battery draining. Pls prepare extra batteries. Replace batteries if microphone cuts out while you're speaking.

  • Keep away from the speaker at least 10 feet and don't point the mic at it, to avoid getting feedback.

  • This lapel mic is unidirectional. Clip it as close to under your chin as possible and speak to it within the right angle.

  • Roles of Sex Hormones and Gender in the Gut Microbiota

    Molecular pathway of estrogen receptor (ER) action. Typically, estrogen binds to the ligand-binding domain of receptors in the nucleus, which causes a conformational change. Estrogen-responsive elements (ERE) mediate genomic effects. RE, response element; TF, transcription factor; GF, growth factor; GF-R, growth factor receptor; CoA, co-activator; CoR, co-repressor; MAPK, mictogen-activated protein kinase; PI3K, phophoinositide 3-kinase; Src, proto-oncogene tyrosine-protein kinase; AP-1, activating protein-1; Sp-1, stimulating protein-1. Adapted from Nie et al.16

  • Variations in Clinical Practice of Esophageal High-resolution Manometry: A Nationwide Survey

    Measurement parameters utilized to determine the esophageal motor function. (A) Esophagogastric junction (EGJ). (B) Esophageal body. EGJ-CI, esophagogastric junction-contractile integral; IRP, integrated relaxation pressure; LES, lower esophageal sphincter.

  • Normal Values of High-resolution Manometry Parameters With Provocative Maneuvers

    High-resolution manometry test swallows and maneuvers. (A) Supine 5 mL liquid; (B) upright 5 mL liquid; (C) viscous (apple sauce); (D) solid (graham cracker); (E) multiple rapid swallow; and (F) rapid drink challenge. Integrated relaxation pressure (IRP) and distal contractile integral (DCI) were 11 mmHg and 1760 mmHg·cm·sec (A), 8 mmHg and 1950 mmHg·cm·sec (B), 7 mmHg and 1600 mmHg·cm·sec (C), 10 mmHg and 1400 mmHg·cm·sec (D), 4 mmHg and 4600 mmHg·cm·sec (E), and 3 mmHg and 0 mmHg·cm·sec (F), respectively.

  • Rectosigmoid Localization of Radiopaque Markers for Identifying Defecation Disorders in Patients With Chronic Constipation: A Retrospective Cohort Study

    Our diagnostic algorithm of defecation disorders using a colonic transit study. DD, defecation disorders; DRE, digital rectal examination; NTC, normal transit constipation; STC, slow transit constipation; RS, rectosigmoid colon.

  • Inter-hemispheric Functional Connections Are More Vulnerable to Attack Than Structural Connection in Patients With Irritable Bowel Syndrome

    Statistical maps showing voxel-mirrored homotopic connectivity (VMHC) differences between irritable bowel syndrome (IBS) and healthy controls (HCs; P < 0.05, corrected with Alphasim). IBS patients showed much higher VMHC in superior occipital gyrus, middle occipital gyrus, precuneus, posterior cingulate gyrus, and angular gyrus (red), while lower in supplementary motor area (blue). The color bar indicates the T-value from t test between groups.
