Suggestions for Installation
General Suggestions
❍Provide for cable or an antenna for radio and television reception. The type of building and the location
could effect reception.
❍Use televisions with "Audio Out" or preferably "Line Out." If you are using televisions with "Audio Out"
the external speakers should be turned off and the volume set to the highest level.
❍Televisions should be arranged so that every user has a clear view of all televisions. Stagger the rows of
cardio equipment placing shorter pieces (e.g., recumbent bikes) in front and taller pieces (e.g., steppers)
toward the back.
❍Tuners or receivers may be used. If you are using a receiver, DO NOT use the speaker out connections as
this may damage the equipment. Instead use the "Record Out" or "Line Out."
❍Group the audio components in a single location to minimize cabling.
❍If the audio components are stacked in a stereo cabinet insure there is adequate ventilation. The Cardio
Theater Amplifier requires a minimum one inch (1") clearance on both sides for ventilation.
Main Amplilfier:

❍Place the Main Amplifier in a well ventilated area with the front and back easily accessible.
❍Number the audio components to match corresponding channel selections on the Upper Monitors.
❍Label cables as you connect them to the Main Amplifier. This will avoid any guess work in the future.
Upper Monitors:
❍When mounting Upper Monitors to equipment, take care not to interfere with the normal operation of the
equipment.
❍Likewise, the Coiled Cable connecting the Upper Monitor to the Floor Monitor should not interfere with
normal operation of the cardiovascular piece.
❍If mounting the Upper Monitor to a control panel, avoid covering controls or indicators.
Floor Monitors:
❍Floor Monitors should be secured to the floor, or in a sub floor. DO NOT attach the floor monitor to the
cardiovascular piece. This will cause problems when machines are moved (i.e., elevating treadmills), or for
cleaning.
❍Floor Monitors may be screwed down using the mounting holes or adhered to the floor using a strong
double-sided cloth tape.
Cabling and Connectors:
❍DO NOT SUBSTITUTE ANY TYPE OF CABLE OR CONNECTOR OTHER THAN THAT SPECIFIED
BY THE MANUFACTURER.
❍The Coax Cabling and the Floor Monitors can be installed under the floor, either in a sub floor or in a
conduit. In lieu of a sub floor or conduit, use an above-floor conduit system to protect the cabling, such as
a rubber raceway.
❍The most predominant method of covering the Coax Cable above floor is a rubber raceway molding
(Wiremold catalot number 1500). It is a narrow cable cover with beveled edges and a low profile that will
not interfere with traffic flow. It may be secured to the floor with double-sided cloth carpet tape, screws,
or nails. Wiremold catalog number 1500 may be purchased from Cardio Theater at (800) CARDIO-1, or
[phone].
❍There are four (4) output connectors on a 16-channel Amplifier and two (2) on an 8-channel Amplifier.
Use all four (or two) and divide the Upper Monitors evenly among them. For example: if you have 20
Upper Monitors on a 16-channel system, connect 5 Upper Monitors to each of the output connectors.

❍The maximum total length of the Coax Cables connected to any one output is 400 feet.
❍A maximum of 20 Upper Monitor sets can be connected on a single Coax line.
❍The system is designed to work with the monitor boxes connected in a daisy-chain or serial configuration.
❍DO NOT CREATE BRANCHES OFF A MAIN LINE! See drawing below:

System Connections
Distribution Amplifier
NOTE: MAKE ALL CONNECTIONS TO MAIN AMPLIFIER, UPPER MONITORS &
AUDIO DEVICES WITH POWER OFF.
Step 1
Connect the audio components:
●to inputs 1 through 16 for a 16-channel Amplifier; or
●to inputs 1 through 8 for an 8-channel Amplifier.

Step 2
Connect the Coax Cable to outputs A,B,C, and D.
❍A maximum of 20 Upper Monitors can be connected
to a single output.
❍For systems using multiple outputs, we recommend
connecting as follows:
1 Cable to output A
2 Cables to A & C
3 Cables to A, B, & C
4 Cables to A, B, C, & D
❍For a more balanced system, evenly divide the Upper
Monitors among the four outputs (two outputs on an 8
channel system). For example: On a system with 40
Upper Monitors, install 10 on each Coax Line (20 on
each Coax Line for an 8 channel system).
Step 3
Connect to the optional Public Address input as
follows:
●Terminals #1 and #2 to the activation switch on the
PA.
●Terminals #3 and #4 are line level from the PA
System.
Step 4
Use the power cord supplied to connect Main
Amplifier to a 110 or 220 Volt AC outlet as applicable.
●CAUTION: Before connecting to 220 volt outlet be
sure voltage selector on back of amplifier is set to
220. (See "Distribution Amplifier - Back")
Upper Monitors and
Floor Monitors

Step 1 From the Main Amplifier, connect the Coax Cable to as
many as 20 Floor Monitors using the Coax Cable and "T"
Connectors supplied, as shown above.
Step 2 Connect the "T" Connectors at each location to the Floor
Monitor.
Step 3
Use the Coiled Cables to connect each Floor Monitor to an
Upper Monitor.
Note: The plug for the Coiled Cable is on the back of the
Upper Monitor.
Step 4 On the last "T" Connector of each run of Coax Cable, a
Terminator (supplied with this system) must be installed for
proper operation.

Attaching Upper Monitors
The Upper Monitor can be installed on any piece of equipment.
For equipment with round handles or railing,
Upper Monitors are supplied with a build-in
mounting block.
Align the Upper Monitor on the handle or rail as
desired.
Use two of the supplied Plastic Wire Ties to
attach the Upper Monitor to the handle or rail.
Pull wire ties firmly to secure.
This method is the preferred method of attaching
the Upper Monitor to minimize interference with
control panels and displays.
For equipment with flat control panels but no
hand rails, SuperLock (a form of super strong
velcro) may be used.
Determine the best mounting position.
Clean the mounting surface thoroughly.
Remove the protective cover from the adhesive
strip.
Position the Upper Monitor and press firmly for
the adhesive to grip.
CAUTION: When attaching to a control panel, care
should be taken to avoid blocking access to
controls or illustrations.
