Sennheiser’s application engineers have used their expertise to develop the ACA 3, a compact and easy to deploy 2 x 4:1 antenna combiner compatible with all analogue and digital Sennheiser wireless stationary receivers operating in the supported frequency range of 470 to 798 MHz. Sennheiser supports the use of distributed antenna systems with a range of high-specification antenna combiners to allow wireless microphone coverage over multiple rooms and large or complex sites. With the increasing demand for “zone” systems in various situations including large churches, broadcast installations, outdoor sporting events and reality TV shows, Sennheiser’s engineers have used this expertise to develop the ACA 3, a compact and easy to deploy 2 x 4:1 antenna combiner compatible with all analogue and digital Sennheiser wireless stationary receivers operating in the supported frequency range of 470 to 798 MHz.
