- Overview
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.
Key Features
2 x 4:1 combiner at unity gain
Switchable DC supplied on each antenna input for head amps or active antennas, e.g. AB 3, AB 3700, A12AD, AB 9000
RF from each of the eight antenna inputs is switchable to isolate unused antennas
LEDs indicate input state; RF on, DC on and DC current overload (e.g. faulty ‘short circuit‘ antenna cable)
