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 analog and digital Sennheiser wireless stationary receivers operating in the supported frequency range of 470 to 798 MHz.

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 analog and digital Sennheiser wireless stationary receivers operating in the supported frequency range of 470 to 798 MHz.

The ACA3 allows upto 4 x pairs of diversity aerials to feed a single radio mic system. So for example, a performance with 4 x areas could setup a pair of diversity aerials in each area, connected to the radio mic system via the ACA3.
