The Sennheiser ASA 1 active antenna splitter
The ASA 1 active antenna splitter has been designed to enable routing of UHF antenna signals to several receivers in a multichannel system. Up to four diversity receivers may be supplied with signal by only two antennas. The integral RF amplifiers ensure that the ASA 1 does not introduce any additional UHF signal loss.

The ASA 1 incorporates DC distribution to enable simultaneous powering of up to four receivers and two antenna boosters via its BNC sockets. The antenna boosters may be required in order to compensate for cable losses due to long antenna cables. A single NT 1-1 mains unit (to be ordered separately) is required to power the ASA 1, the connected receivers and antenna boosters.

By linking two ASA 1, an 8-channel diversity system can be operated with only two antennas.

Using the GA 3 rack adapter, two ASA 1 or one ASA 1 and one stationary receiver (e.g. EM 100 G3, EM 300 G3 or EM 500 G3) can be mounted into a 19” rack.

The ASA 1 is suitable for the following areas of application:

  • Multi-channel RF installations
  • Permanent installations in small conference centres and similar venues


Delivery includes
1 ASA 1 antenna splitter
1 set of device feet
8 BNC cables
1 instruction manual

You additionally require the NT 1-1 mains unit with a suitable mains connector
