Resetting the
Headphones
If you ever want to return the
headphones to their factory presets,
simply reset the headphones by
triggering the reset button on the
right headphone with a paper clip.
Important Note About Audio Outputs
If possible, use a xed-level (or line-level) audio output from your
audio source. This kind of output provides a consistent level of audio
that doesn’t change when you adjust the source’s volume control.
Fixed-level audio outputs from stereo receivers/amps are typically
designated as tape or VCR audio output connections, sometimes
marked on the component as ‘TAPE OUTPUT,’ ‘TAPE OUT,’ ‘TAPE REC,
or ‘TAPE RECORD or REC OUT.’
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). Outputs
from DVD players are almost always xed.
Important: Jacks labeled CD, DVD/DVR, PHONO, or tape playback
(PB) are INPUTS and will not work with the transmitter.
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 headphones, and
may require an adjustment of the volume level of the audio source to
produce a signal strong enough for the transmitter.
Hints:
• 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.
