Overview

Auto-Scanning UHF wireless system allowing quick and easy selection of an interference free operating frequency. This is particularly useful when there are many existing systems in use nearby. A range up to 100m is possible in ideal conditions. Incorporates diversity reception ensuring a consistent and clear microphone signal with minimal dropout and noise interference. 16 channels allow interference free operation with multiple systems in the one location. Noise reduction system automatically compensates for high level sound inputs thus avoiding distortion. Channel and volume settings are adjusted via front panel. Output is via 3 pin XLR balanced or 6.35mm unbalanced. LEDs are provided for displaying system status. The system operates from 12-18V dc (power supply included). The C 8864B transmitter is compatible with a wide range of microphones. It also features an instrument level capability for connecting a guitar using the C 8909 lead.

Rack Mounting

To mount a single receiver into a rack, use C 8889 rack mounting ears. To mount two receivers side by side in 1RU of rack space, use the hardware included with the C 8860B.
