Sumico WMS4H is a professional 4-channel wireless microphone system from the world-renowned brand Sumico. Sumico WMS4H wireless microphone system impresses with its elegant and sophisticated design. The receiver unit is built from a durable alloy for enhanced sturdiness. On the left side of the receiver, the Sumico logo and model name WMS4H are prominently displayed. On the right side, an LCD screen provides separate information for all four channels, corresponding to the four microphones. Flanking the screen are rotary control knobs for each of the four channels, equipped with LED indicators to enable quick and easy adjustments even in low-light environments. The front panel of the receiver also features two pull handles, and rack ears are provided on both sides for convenient rack-mount installation.
The microphone body is made from high-quality alloy with a matte finish that is scratch-resistant and sweat-proof, while the mesh grille covering the microphone head is constructed from durable stainless steel, designed to withstand dents and impacts from accidental drops. Inside the grille, there is a thin fabric layer that provides effective sound filtering while also reducing moisture penetration from the singer’s breath, protecting the microphone capsule from corrosion and rust. At the center of the microphone handle, there is a power on/off button and a small LCD display that shows the frequency and battery status.
Sumico WMS4H delivers clear and precise sound transmission without interference from mobile phones or computer electromagnetic fields. Utilizing the popular UHF frequency band, Sumico WMS4H provides stable, wall-penetrating performance, minimizing signal dropouts and preventing common issues like audio loss found in conventional wireless microphones. Operating within the 610 MHz – 694 MHz frequency range, the system offers 60 selectable frequency channels, giving users flexible options and ensuring reliable performance even in events with multiple microphones operating simultaneously.
Sumico WMS4H features highly sensitive sound pickup with excellent audio capture, delivering detailed, clear, and smooth vocals without causing harshness or distortion when singing.
Sumico WMS4H is designed with advanced anti-feedback technology, ensuring the microphone remains free from howling or screeching noise while singing. It delivers powerful, full-bodied, and clear vocals, supporting users with weaker or thinner voices to achieve stronger projection and better overall performance.
The microphone handset is equipped with an auto-mute sensor feature: when the microphone is placed on a table, it will automatically pause audio signal transmission after 3 seconds to eliminate feedback and prevent music from being picked up by the microphone, helping to maximize battery efficiency. However, once you pick up the microphone, you can sing immediately without pressing the power button again. After 20 minutes of inactivity, the microphone will automatically power off. To enable or disable this feature, while the microphone is powered on, press and hold the power button for about 5 seconds.
Sumico WMS4H is equipped with an integrated accelerometer sensor that automatically activates the Mute mode when the microphone is dropped, preventing the “pop” sound from being transmitted to the speakers. This feature protects the sound system from potential damage and avoids sudden loud noises for listeners.
Sumico WMS4H features automatic frequency scanning and auto frequency synchronization between the receiver and the microphone handset, allowing for quick and effortless setup.
