About Variable-Level Audio Outputs:
A variable-level output, such as a headphone jack or certain RCA-type outputs,
provides an audio signal that changes with the volume level set on the audio
source. As the volume of the audio source is adjusted up and down, so is the
audio signal strength sent to the transmitter. This can affect the quality of sound
generated by the speaker, and may require an adjustment of the volume level of
the audio source to produce a signal strong enough for the transmitter.
Hint: On most bookshelf-type or compact stereo systems, inserting a
headphone plug into the headphone jack results in automatic cutoff of the
regular, or hard-wired speakers.
Hint: Most TVs, regardless of age or price, have variable outputs. If you are
unsure which of your TV audio outputs is xed, refer to the TV instruction
manual. Some TVs have outputs that can switch between variable and xed.
When given a choice, xed is always recommended.

About Fixed-Level Audio Outputs
A xed-level, or line-level audio output is considered ideal since it provides an
audio signal unchanged by adjustments to the audio source volume control.
Fixed-level outputs from TVs are usually marked as ‘Constant,’ ‘Fixed,’ or ‘Select.’
If they are not marked as such, they are probably variable outputs (see “About
Variable-Level Audio Outputs” below).
