Active antenna combiner for evolution wireless G4 systems. The AC 41 operates up to four wireless stereo transmitters from the ew series using one shared antenna. Power is supplied to the SR IEM G4 transmitters over the BNC cables via NT 3-1 power supply (included with the AC 41), making separate power supplies for the transmitters obsolete.

Key Features Up to 4 wireless stereo transmitters using one antenna Power supply via BNC cables ensures efficient powering, no need for additional power supply units for the SR IEM G4 Compatible with G4 and G3 systems Specufications Frequency range                               470 - 870 MHz / 470 - 608 MHz Impedance                                         50 Ω Dimensions                                        approx. 212 x 168 x 43 mm Weight                                                approx. 1470 g Power consumption                            max. 3.4 A (with connected transmitters) Storage temperature                          -20 °C to +70 °C (-4 °F to 158 °F) Operating temperature                       -10 °C to +55 °C (14 °F to 131 °F) Power supply         13.8 V DC (with tabletop power supply unit NT 3-1)11.4 V DC (protected against reverse supply), 350 mA RF input                                              max. 30 mW per input Transmission loss                               0 dB (±1 dB) Operating relative humidity                 5 to 95 %
