The CAD GXLD2HH Dual-Channel Digital Wireless Microphone System with Two Handheld Transmitters is intended for up to two vocalists or speakers who want the ability to control the sound of their voice using handheld microphones and the flexibility of passing a mic around, when performing on stage, or for school functions, corporate trainings, houses of worship, and more. The system consists of a two-channel receiver and two handheld wireless microphone transmitters. It delivers digital high-definition audio and operates in the AI: 909.3 to 926.8 MHz frequency band, which is free from TV and FCC regulatory issues. The receiver features volume knobs for each channel and RF indicator lights to show connectivity between the receiver and the transmitters. The back panel includes two balanced XLR output connectors and an unbalanced, mono Mix output on a 1/4" connector. Two antennas with advanced dipole technology help increase the operating distance. The microphones feature CADLive D38 dynamic capsules with supercadioid polar pattern for reduced feedback in live situations. The mics run on two AA batteries for approximately 10 hours and are equipped with on/off and mute functions to help conserve battery life.
