Installation Requirements
Review the following requirements before installation:
• To ensure the best range and audio quality, select a location
without any major internal obstructions, such as metal support
posts, between the transmitter’s antenna and receivers installed
on the exercise equipment. The antenna and receivers should also
be installed so they are within 150 feet (50 meters) of each other
and are in direct line of sight.
posts, between the transmitter’s antenna and receivers installed
on the exercise equipment. The antenna and receivers should also
be installed so they are within 150 feet (50 meters) of each other
and are in direct line of sight.
• Cardio Theater recommends that you group audio components
together to minimize cabling. You can install the transmitter in a
rack with other audio components if desired.
rack with other audio components if desired.
• If the audio components are stacked in a cabinet, make sure the
equipment has adequate ventilation to avoid overheating.
• Install the antenna nearby so it is vertical. Do not install the
antenna so it is mounted horizontally, which will decrease its
transmission range. In addition, the antenna should not touch or
come near other transmitting antennas or metal objects. Be sure
to route cabling and power cords away from the antenna, so they
do not cause interference.
transmission range. In addition, the antenna should not touch or
come near other transmitting antennas or metal objects. Be sure
to route cabling and power cords away from the antenna, so they
do not cause interference.
• You can mount the antenna up to 50 feet (15 meters) from the
transmitter. A coax cable (RG-58 or RG-8) connects the antenna
to the transmitter and eliminates any interference issues between
these two components. Using a higher quality (lower loss) cable
will allow a greater distance between the transmitter and antenna.

will allow a greater distance between the transmitter and antenna.
• Each audio component connected to the transmitter requires a
unique channel number. Channel numbers on a transmitter
determine frequencies. There is no correlation between channel
numbers on a transmitter and channel numbers shown on
receivers when they are programmed.

• The xTV-9TM has four programming modes to support different
situations and countries. Each mode has different frequencies
assigned to its channels. Refer to the following tables to identify
the mode appropriate for your installation.
