The audio input to the WFM100 can be connected to either the low-level fixed audio output or a variable level
audio output (such as a speaker or headphoen output). If it is connected to a low-level output, only the volume
control on the earphones needs to be adjusted to control the volume level. If it is connected to a variable level
output, the volume level adjustment needs to be done at both the source and at the headphones.
