    Is a DD1494 and an SSRA required for a commercial audio-visual system using a wireless microphone?


    Yes.  There might be other devices that could be affected or they could interfere with your device. Frequency management is becoming so much more important since the demand for bandwidth continues to increase which makes saturation and other frequency bands a carefully managed propositon. By submitting a DD Form 1494, you will have formally notified the authorities as directed by DoD since you will be emitting a signal to send data albeit a nominal one.
