The Brief
Integrated Audio Solutions where contacted by Echunga Primary School with wireless system tuning and drop out issues. After an initial site visit it was quickly established the schools wireless microphones system was still on the old frequencies (694-820 MHz), adding to the issues the antennas (6) where installed in the back of the equipment rack causing suspected intermodulation issues and obstructed site lines.

The Resolution
Equipment rack was stripped, power amplifiers filters cleaned, equipment reinstalled with blank panels and the wiring dressed and labelled. Three Electro-voice R 300 Hand Held systems where installed along with a Electro-voice APD4+ Antenna Power Distribution System allowing for the expansion to a fourth unit in the future. The APD4+ allows for 8 antennas to be managed down to two. The two antennas where mounted on the side of the equipment rack for optimised site-line performance.
