Description:
The R-32AUs reliable performance and resistance to wear and tear provide the best possible reception within the required coverage. The gain setting is used for enhanced amplification of signal reception. The R-32AU can be mounted on a mic stand suspended from the ceiling or attached to the wall using an integrated rotatable stand.
Characteristic:
• With low noise signal amplification for signal enhancement.
• Works with Relacart wireless receivers and antenna distribution systems.
• Lightweight and sleek exterior construction for easy carrying and erection installation.
Installation:
• The antenna can be connected to the receiver or antenna distribution system using any 50 ohm low loss coaxial cable.
• Only available for receiver and antenna distribution systems with antenna power.
• The antenna should be aligned to the area covered.
 
 Antenna placement:
When fixing the antenna you should pay attention to the following items:
         • The antenna and receiver must use the same frequency band.
         • The antennas should be fixed at least 1.2 meters away from each other.
         • Keep the antenna away from sources of interference (such as large metal objects).
         • Adjust the antenna position and avoid any obstructions between the antenna and the transmitter.
 
IMPORTANT: Before going on perform a walking tour test to check the signal coverage. Test the various placement effects of the antenna to find the best placement. The “dead spot” should be marked according to the actual situation and the performer should be prompted to avoid these areas.
