Analog Stereo Line Input: This type of input source allows connection to the audio device with either the RCA
analog audio output jack or a headphone mini-jack/3.5mm stereo audio output jack.
IMPORTANT: Make sure to connect to terminals on your TV/audio device marked as audio OUTPUTS. Both
audio input and audio output connections can be made using these types of connectors/cables. Many newer
televisions D
ON’T have audio OUTPUT connections of this type and CANNOT be connected to the transmitter
using this method.
If connecting to the RCA audio output jacks, use a cable (included) with stereo RCA jacks (usually one red
and one white or black) on one end and a 3.5mm stereo mini-jack on the other. If connecting to a headphone
jack or 3.5mm stereo mini-jack, use a cable that has 3.5mm stereo plugs on both ends
. (A conversion cable
is included. Connect the male/female RCA jacks to each other. This will leave 3.5mm stereo plugs on either
end of the combined cables to connect to TV/audio device.)
After the connection has been made to TV/audio
device, plug the other end of the cable int
o the port on the transmitter marked “Line Input” (Diagram #9).
NOTE: Do Not connect the transmitter to an amplified audio source. The transmitter is manufactured with
sensitive components that are designed to work with line-level voltages Only. Connecting the transmitter to
an amplified audio source will damage the unit and void the warranty.
Digital Optical Input: This input selection can be used if TV/audio device has a digital optical audio output or
S/PDIF or TOSLINK jack. This connection allows for the highest quality audio transmission and is the
preferred method if available. This connection requires the use of a fiber-optic or TOSLINK cable made
specifically for this type of connection. (This cable is NOT included but is available from ARG, order #ARG-
CA017 or purchase from local electronics retailer.) One end of the cable is inserted into the jack marked
“Optical Audio Output”, “S/PDIF” or similar description on TV/audio device. Insert the other cable end into the
port on the transmitter marked with
“Optical Input” and the symbol that looks like this: XXXXX (Diagram #10).
Make sure the ends of the cable are securely connected to the ports on both ends. Usually these plugs will
“click” into place when they are inserted properly.
(NOTE: these cables are usually shipped with clear plastic
protective covers on the ends. Be sure to remove these covers before connecting the cable.)
Digital Coaxial Input: Choose this selection if audio device is equipped with a digital coaxial audio output. The
output terminal for this connection looks like a standard RCA-type jack and will be orange in color. A cable
that is specifically designed to transmit digital audio signals is needed. (This cable is NOT included but is
available from ARG, order #ARG-CA
016 or purchase from local electronics retailer.) DON’T use a standard
RCA cable as it is NOT equipped with the proper shielding and may cause interference with other electronic
devices located in close proximity to the cable. Plug one end of the cable into the orange terminal on TV/audio
device labeled
“Digital Audio Output” or similar. The other end plugs into the white RCA jack on the top of the
transmitter marked “Coaxial Input”.
Note
– DO NOT connect more than one audio source to the transmitter at a time. Connecting multiple
cables can cause permanent damage to the unit.
Setting the Audio Input Source -
You MUST set the input source on the transmitter to correspond to the input you
have chosen as the connection. This directs the transmitter to determine the type of audio signal to “read” and where
to find it. Failure to set the input source to match the connection will result in poor or no audio being sent from the
transmitter. P
ress the “SET” button (Diagram #1) while it is in the “LOCK” mode to set the input source on the
transmitter. (The “LOCK” icon will be illuminated on the display.) Each time the “MODE” button is pressed, the
transmitter will toggle between the three input sources: Analog line, Digital coaxial, Optical, then repeat. Again, make
sure the setting corresponds to the cable type used to connect the transmitter to the audio source.
Confirming Signal Acquisition
–
When properly connected to the TV/audio source (assuming the output for that
device has been set correctly) and the corresponding input source has been selected; the transmitter will detect the
audio signal. Make sure the transmitter is receiving and has detected a usable audio signal from the TV/audio source
by observing the digits in the display that represent the volume level (Diagram #2). If the digits are steadily lit and NOT
flashing, the transmitter is receiving and has detected a good audio signal from the device. If the digits are flashing,
the transmitter has detected either a weak signal or no audio signal at all. If weak/no signal, check connections and
the input setting on the transmitter and verify that the TV/audio device is generating a usable signal. If the device is
not sending a good signal, check to see if the volume level on the TV/audio source is adjusted too low. The level should
be set to approximately 75% of the maximum. Turn up the volume, then turn off the speakers on the device by changing
the setting through the on-
screen menus. (See the owner’s manual for the device for instructions.) If the problem
persists, contact the technical service department for your TV/audio device or ARG for assistance.
