WMU-401 4-Way UHF Microphone


The WMU-401 is the perfect entry-level system into advanced UHF wireless technology if several wireless microphones are needed at the same time. Utilizing a narrow band gap (ISM band for Europe) to its maximum of 4 parallel systems, a frequency choice becomes obsolete due to the required minimum band gap. The WMU-401 comes in a sturdy and optionally rack-mountable metal case, and can be configured in a variety of possible setups with any mix of handheld and beltpack transmitters, the latter either with headset or tie-clip lavalier microphone. The modular construction provides enhanced interference protection and greatest ease of service.
