The Redback® 700 channel UHF 520-550MHz radio microphone system is a professional system incorporating true diversity reception. This ensures a consistent and clear microphone signal with minimal dropout and noise interference. 700 channels allow interference free operation with up to 12 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. The LCD screen displays selected channel, frequency and RF/AF signal strength. Transmitters can be recharged via a front panel port (when fitted with rechargeable batteries). A range in excess of 100m is possible in ideal conditions. Output is via 3 pin XLR balanced or 6.35mm unbalanced. The system operates from 12V DC (power supply included). Also included in box is a 0.5m Male to Female XLR 3 pin lead.
