HM604U handheld wireless microphone
Product features:
1. The built-in frequency of 3 marshalling and stacking machines is adjusted with one key. The same frequency band can be easily used for three sets of stacking machines at the same time.
2. with IR infrared automatic frequency matching function, one-button automatic frequency locking.
3. The volume of four channels can be adjusted independently. 4+1 audio output is provided.
4. A variety of transmitters are available. The conference/hand hold/collar can be mixed and used in the launcher.
5. Backlit LED display indicates RF and AF signal strength, frequency, frequency group/channel and other working states.
6. With the same working frequency of 4 channels, transmitters can be exchanged at any time, greatly enhancing the flexibility of operation.
7. Adopt the latest UHF band wireless audio transmitting chip module IC. It has excellent RF performance and audio performance, and provides customers with professional sound quality experience.With the noise control of noise lock and digital pilot technology, when the transmitter is off, the pilot control will mute the AF signal to suppress the noise, and the corresponding channel of the receiver will be mute.Ensure the effective blocking of the dry signal.
8. Optional headwear or jacket is supported.
