Q Audio QAD-4 Wireless Microphone Aerial Distributor

Description

QAD-4 4 way UHF aerial and power distributor for operating up to four UHF multi-frequency diversity receiver units with one pair of antennas

The Q-Audio QAD-4 is a professional UHF wideband antenna splitter designed for use with up to four radio microphone receivers. Its dual 1:4 configuration supports diversity systems and is compatible with two Q-Audio QDP-1 active antennas or most BNC-connected UHF antennas. Ideal for reducing RF interference and signal dropouts in multi-channel wireless setups.

This UHF wideband antenna splitter is engineered to support RF signal distribution to up to four radio microphone receivers, making it well-suited for demanding multi-channel wireless audio environments. Utilising a dual 1:4 active splitter architecture, the unit accommodates up to four diversity receiver systems—each requiring two discrete RF inputs—via two independent signal paths. This allows for the integration of two Q-Audio QDP-1 active directional antennas, or most other BNC-connected UHF antennas, providing broad compatibility and flexibility in system design. The splitter maintains consistent impedance matching and offers low insertion loss to preserve signal integrity across the entire UHF spectrum. By centralising antenna distribution and reducing the need for multiple passive splitters or redundant antennae, the system significantly reduces the potential for intermodulation distortion and RF congestion. This results in enhanced frequency coordination, improved reception stability, and reduced dropout risk, making it an essential component for high-density wireless microphone deployments in live production, broadcast, and theatrical applications.

Wireless microphone systems require knowledge of OFCOM licensing and the working practices and requirements when using multiple wireless microphones simultaneously and systems should be installed and set-up by experienced users

Please note that wireless microphone transmitters will only work with their matching wireless microphone receivers from that manufacturers matching range of equipment. Digital wireless microphone transmitters and receivers are not compatible with or suitable for use as spare components in older analogue wireless microphone systems and vice-versa.
