Please do not touch the antennas during operation because
human body prevents radio transmission effectively.
If you plan to play audio wirelessly in a crowded room, please
mount both transmitter and receiver above people close to the
roof of the room to enable free transmission.
Please don't place the AMP Receiver on the floor since that
location is not optimal from antenna performance point of view.
RCA2AMP audio transmission has a constant delay of 20ms. This
delay moves the speakers effectively about 6.9 meters further
away from the AV Amplifier. You can notice this when carrying out
loudspeaker adjustments with your AV amplifier.
