1. Controls and Indicators

Application

The AD 808 is a 4-channel active antenna combiner operating in the frequency range from 600 to

900 MHz. Up to four wireless transmitters can be combined into one transmitting antenna for

professional multi-channel applications.

2. Installation

2.1 Installation of the input signal

Use coaxial cables with TNC connectors to connect the outputs of the transmitters to the inputs of the

AD 808 combiner. Make sure that the coaxial cables are as short as possible for optimum operation.

Up to four transmitters can be connected to the antenna combiner.

2.2 Antenna installation

For optimal transmission the antenna connected to the combiner should operate in the same

frequency band as the transmitter antenna.

2.3 Installation of remote antennas

To install remote antennas use the AT 70 or AT 90 T. Both antennas can be mounted to the wall by

using the MS 10 wall mount bracket or onto a standard microphone stand. For connecting use high

quality coaxial cables which should be as short as possible. For optimal reception make sure that the

antenna is positioned above the audience and away from obstacles.

3. Important Note

The combiner operates in the frequency range between 600 and 900 MHz. It works with any transmitter

within this range. For optimal transmission make sure that the transmitting antenna operates in the

same frequency band as the transmitter. We recommend using the AT 90 T or AT 70 antenna to

connect to the AD 808 combiner. For connecting use 50 ohms coaxial cables which are not longer than

10 metres.
