1. Built-in 3 group stacking machine frequency, a key access, the same frequency band can be easily stacked three sets of machines to use.
2. With IR infrared automatic frequency function, a key to automatically lock frequency.
3. Four-channel volume independent adjustable, providing 4 +1 audio output, four-channel audio volume output independently controllable.
4. Provide a variety of transmitter options, the transmitter conference / handheld / lapel can mix and match, do not interfere with each other.
5. Backlit LED display indicates the RF and AF signal strength, frequency, frequency group / channel and other working conditions.
6. Using the same operating frequency of 4 channels, making the transmitter can be exchanged at any time, greatly enhancing the operational flexibility.
7.Using the latest UHF band wireless audio transmitter chip module IC, with superior RF performance and audio performance, to provide professional-quality sound experience. With noise-locked mute control and digital pilot technology, when the transmitter is off, the pilot control to mute the AF signal to suppress noise, while the receiver corresponding channel mute. To ensure the effective signal interference of dry barrier.
