USING YOUR HEADPHONES
IMPORTANT NOTE ABOUT AUDIO OUTPUTS
If possible, use a fixed-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 fixed.
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.
•Most TVs, regardless of age or price, have variable outputs. If you are unsure which of your TV audio outputs is fixed, refer to the TV instruction manual. Some TVs have outputs that can switch between variable and fixed. When given a choice, fixed is always recommended.
