IMG STAGE LINE CH70 UHF Wireless Handheld Microphone System

The IMG STAGE LINE CH70 UHF Wireless Handheld Microphone System is a professional-grade audio solution offering exceptional clarity and robust performance for a wide range of applications. Featuring advanced UHF PLL (Phase-Locked Loop) technology, the system provides reliable, interference-free transmission across 80 selectable channels within the 863-865 MHz range, ensuring a stable connection even in crowded RF environments.

The system utilises a true diversity system to minimise dropouts and maximise signal integrity by intelligently switching between two internal antennas. This is complemented by the ACT (Automatic Channel Transfer) function, which allows the selected frequency from the receiver to be seamlessly transmitted to the handheld microphone via infrared signal for quick and easy setup. An autoscan function further simplifies operation by automatically finding the clearest available channel.

System Performance and Features

The handheld transmitter boasts a high-quality cardioid microphone capsule, which effectively rejects unwanted sound from the sides and rear, focusing on the vocal source. For power management, the transmitting power can be switched at the microphone between high and low settings to optimise battery life and range. The operating range extends to approximately 30 metres under optimal conditions.

Both the receiver and transmitter feature clear status indicators. The receiver display shows channel, antenna A/B selection, ACT status, and AF audio level. The microphone transmitter indicates the channel and remaining battery power. The receiver is housed in a robust metal housing for durability in professional touring and installation settings.

Audio Quality and Connectivity

Engineered for superior sound, the system delivers an audio frequency response of 50Hz to 18kHz (±3dB) and a wide dynamic range of 120dB. It maintains a high signal-to-noise (RF S/N)**
