S800H7 Dual-Channel True Diversity UHF Wireless Microphone System
Product Overview
The S800H7 is a professional dual-channel UHF wireless microphone system designed for large-scale performances, school playgrounds, stadiums, houses of worship, conference venues, and other applications requiring high-fidelity sound and long-distance wireless transmission.
Dual-tuner true diversity technology continuously compares independent antenna signals and automatically selects the stronger reception path, helping reduce signal dropouts in complex environments. The system provides 128 selectable frequencies per channel, automatic clear-channel scanning, infrared synchronization, and digital ID verification for reliable transmitter pairing.
Adjustable transmitter power, receiver squelch, and digital electronic volume control allow the system to be optimized for different venues. Under open and unobstructed line-of-sight conditions, the transmission range can reach up to 500 m. Actual operating distance depends on RF interference, antenna placement, obstacles, transmitter power, and local conditions.

Dual-Tuner True Diversity Reception
Each receiver channel uses two independent tuner and antenna paths. The receiver continuously evaluates signal quality and automatically selects the stronger path, improving reception stability and reducing signal interruptions caused by movement, reflections, and complex venue conditions.
Automatic Frequency Setup
The automatic scanning function searches for available frequencies in the local RF environment. After selecting a clear channel, infrared synchronization quickly transfers the frequency and ID settings to the corresponding handheld transmitter.
Digital ID verification ensures that each receiver channel responds only to the correctly paired transmitter, helping prevent unwanted signals and cross-channel interference.
Professional Handheld Transmitters
The S800H7 handheld microphones feature a durable all-metal body, reinforced grille, and impact-resistant bottom structure for demanding stage and rental applications.
Each transmitter uses a cardioid dynamic capsule to provide focused vocal pickup and improved rejection of surrounding sound. The interchangeable microphone-head design provides additional flexibility for different performance requirements.
Long-Distance Wireless Performance
Enhanced transmitter power and receiver sensitivity provide an operating range of up to 500 m in open, unobstructed line-of-sight environments.
Actual transmission distance may vary according to:
- RF interference
- Buildings and physical obstacles
- Antenna positioning
- Transmitter power settings
- Receiver squelch and sensitivity settings
- Local frequency regulations
Multi-System Operation
For applications requiring more microphones, multiple S800H7 receivers can be coordinated within the same installation.
Up to five receivers can be installed and operated together in one rack. Up to ten receivers can be divided between two racks, supporting as many as 20 wireless microphones under suitable RF conditions.
When operating multiple receivers, coordinate the frequencies carefully and reduce receiver sensitivity when necessary to improve system stability.
