Sound too bright or boomy
Adjust the tone controls to suit the acoustics of
the room and speakers
Handy hint:
You can easily check if the transmitter emitters are working by pointing a mobile
phone camera at them ‒ you don’t need to take the photo but the camera will see the infra
red light from the emitters and show up really clearly!
