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 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.
More Helpful Information
About Fixed-Level Audio Outputs
A fixed-level, or line-level, audio output is considered ideal since it provides an
audio signal unchanged by adjustments to the audio source volume control.
Hint:
Fixed-level audio outputs from stereo receivers/amps will typically be designated
as Tape, Tape 1, and Tape 2 outputs, or VCR audio output connections These outputs are
frequently marked on A/V equipment as ‘TAPE OUTPUT,’ ‘TAPE OUT,’ ‘TAPE REC,
or ‘TAPE RECORD or REC OUT.’
Please note:
Jacks labeled PHONO, CD, LD, DVD or tape or VCR playback (PB) are
INPUTS and will not work with the transmitter.
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” on the next page). Outputs from VCRs are almost always fixed.
Hint:
When connecting to the audio outputs of a VCR, remember that the VCR must be
playing a tape or showing a TV channel for sound to be produced.
Hint:
If your VCR (or other audio source with RCA jacks) only has a single audio
output, you will need another RCA “Y” cable. It differs from the “Y” Cable Adapter
included with this speaker. It will have a single male RCA plug and 2 female RCA jacks.
Connect the dual RCA plugs from the included “Y” cable adapter to the 2 female RCA
jacks on the second “Y” cable, and then connect the single male RCA plug of the second
“Y” cable to the single audio output of the VCR.
