About Fixed-Level Outputs; About Variable-Level Outputs - Advent AW820 Installation And Operating Instructions Manual

3. Plug the 3.5mm mini plug from the "V" Cable Adapter into the headphone jack
(as needed, use the Headphone Adapter Plug
(Q)
to convert the 3.5mm plug to a
1/4" plug).
Note:
If
you select Option
1
or Option
2
to connect the transmitter, the audio level will be
fixed or variable, depending on your equipment.
If
you select Option 3, the audio
level will be variable.
ABOUT FIXEO-LEVEL 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 (stereo, etc.) volume
control.
Hint: Fixed-level audio outputs from stereo receivers/amps will typically be designated
as Tape, Tape I, and Tape 2 outputs, OAT (digital audio tape) outputs, VCR audio
output connections, and auxiliary audio outputs. Tape, Tape I, Tape 2 and OAT
outputs are usually marked as TAPE OUTPUT,' TAPE OUT,' TAPE REC,' OR TAPE
RECORD.' Jacks designated for phono, CD, LD, DVD or tape playback (PB) are
inputs and will not work for purposes of installing the transmitter.
Fixed-level outputs from TVs are usually marked as 'Constant,' 'Fixed,' or 'Select.
I
If
they are not marked as such, they are probably variable outputs (see "About
Variable-Level Outputs," next page).
Outputs from VCRs are almost always fixed.
Hint: When connecting to the fixed audio outputs of a VCR, remember that for the
wireless system to work, the VCR must be active. In other words, turn the TV on
to the channel you would normally use to watch a videotape (channel 3 or 4), turn
the VCR on, then press the TV/VCR button on your VCR remote control one time to
make the VCR the controlling piece of equipment. At this point, you can watch TV
or a VHS tape through the VCR. When changing TV channels, remember to do so
through the VCR. This configuration gives you independent volume control
through your TV (using the TV remote control) and at the speakers.
Hint:
If
your VCR (or other RCA-type audio source you are connecting to) is mono (a
single audio output), you need to acquire an RCA "Y" Cable. It differs from the "Y"
cable included in this kit. It will have a single male RCA plug and 2 female RCA
jacks. Attach the dual RCA cables from the transmitter to the 2 female RCA jacks
on the "Y" cable, then connect the single male RCA plug of the "Y" cable to the
single audio output of the VCR.
ABOUT VARIABLE-LEVEL OUTPUTS
A variable-level output, such as a headphone jack, provides an audio signal to the
transmitter that changes in relation to volume adjustments on the audio source. As
the volume of the audio source goes up and down, so too does the audio signal
strength sent to the transmitter. This can affect the quality of sound you hear at the
speakers.
