It should not do so, however, if it is in a location where radio frequencies will be disrupted. An infrared system would better serve that church. First Lutheran Church in Decorah, Iowa, is pleased with the ALS it installed. Today that's been remedied, says Robert Fitton, president of the church council. We just take a feed off our sound system from the distribution amplifier and send it to the input of the ALS, which broadcasts it to the rest of the facility.
Some people purchase their own units for better comfort and fit.
We have also used the system as a feed into the camera. We just hook up one of the receivers, and the camera picks it up. So the camera gets the sound of the sanctuary no matter where the camera is placed. The church had to use a line attenuator to knock the signal down from that of an earphone to that of a microphone, but that was fairly simple. That ALS feature proved especially valuable during a two-month period when the sanctuary was being painted.
