AKG WMS ANTENNA TECHNOLOGY

Stadium example 2:

Active directional antennas set up far from the stage, with their reflectors oriented to blank out interference sources. The antennas were positioned on a straight line from the interference source (e.g., a local TV transmitter)to the receiving antennas and stage center, several meters above the audience.

Benefits:

•Consistent coverage of entire stage

•Dominant interference source is drowned out

Drawbacks:

•Risk of electrosmog interference

•Long cable runs (boosters may eliminate risk of intermodulation)

Excellent solution for enclosed spaces.

Stadium (theater, opera house) example 4:

Single passive directional antenna set up next to the receiver at the monitor mixing position, one active or passive omnidi- rectional antenna mounted at the opposite end of the stage.

Vorteile:

•Wanted signal is strong enough to suppress electrosmog.

•Far-near problem is smaller than in example 3.

•Simple wiring

Nachteile:

•Unsuitable for large multichannel systems

•The CLA settings for the two antenna channels must be carefully selected, otherwise the receivers may be fed the output signal of the same antenna all the time, effec- tively defeating the diversity function.

Stadium (theater, opera house) example 1:

Active directional antennas set up next to the receivers at the FOH mixing position.

Benefits:

•Consistent coverage of entire stage (no far-near problem)

•Short antenna cable runs

Drawbacks:

•This setup will not work unless the FOH mixing position is high enough above the audience.

•Risk of interference from local TV stations

The best antenna system for enclosed spaces.

Stadium example 3:

Two passive directional antennas set up next to the recei- vers at the monitor mixing position.

Benefits:

•Wanted signal suppresses interference

•Simple wiring

Drawbacks:

•Unsuitable for large multichannel systems due to risk of intermodulation and shadowing (far-near problem)
