Connecting the Transmitter to an Audio Source -
The transmitter has three types of audio input options. The type
of cable used to connect the transmitter to the TV or other audio source will depend on the type of audio output
terminals equipping the signal source device. You MUST set the transmitter to read the chosen input source.
Connection options are:
Analog Stereo Line Input (Diagram #9)
– This input source allows connection to the audio device with either
the RCA analog audio output jacks or a headphone mini-jack/3.5mm stereo audio output jack.
IMPORTANT:
Make sure to connect terminals on 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 DON’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 (conversion cable included). Connect the male/female RCA jacks to each other. The
3.5mm stereo plugs on either end of the combined cables will allow connection to TV/audio device. After the
connection has been made to TV/audio device, plug the other end of the cable into 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 (Diagram #10)
– Use this input selection 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 available to purchase from ARG, #ARG-CA017 or from
any local electronics retailer.) One end of the cable is inserted into the jack marked “Optical Audio Output”,
“S/PDIF” or similar description on the TV/audio device. Insert the other end of the cable 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 en
ds. These plugs will usually “click”
into place when properly inserted. (NOTE: these cables are usually shipped with clear plastic protective end
covers which need to be removed before connecting the cable.)
Digital Coaxial Input (Diagram #11)
– The output terminal for this connection looks like a standard RCA-type
jack and will be orange. A cable specifically designed to transmit digital audio signals is needed. (This
cable is available to purchase from ARG, #ARG-CA016 or from any local electronics retailer.) DO NOT use
a standard RCA cable since it will not have 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 the TV/audio dev
ice 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 -
Set the input source on the transmitter to correspond to the chosen input
connection. This allows 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. The input
setting is displayed on the input indicator (Diagram #14) by the number of decimals showing in the display. Set the
input
source on the transmitter by pressing the “MODE” button (Diagram #6) in the lower left corner of the unit. Each
time the “MODE” button is pressed, the transmitter will toggle between the three input sources: Analog line (no
decimal lit); Digital coaxial (1 decimal lit); or Optical Digital (2 decimals lit).
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 automatically. Make sure the transmitter is receiving and has detected a usable audio signal from the
TV/audio source as displayed in the LCD window (Diagram #1). If the digits are steadily lit (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; check
the input setting on the transmitter; and check to make sure the TV/audio device is generating a usable signal. If the
