Tango Series Audio Controllers
When a keypad command is received and communicated to the source device, there is a LED that lights on the
front of the Tango Controller indicating the processing of the command. If the LED does not light with a
keypad press, then it is possible that the device has not been programmed. If the LED does light, there may be
a problem with the infrared emitter lead.
Tip: For Testing, when you are having IR problems, it is helpful to carry a blinking emitter or a test
emitter to ensure that the commands are being sent to the source. Techniques you can use to help
isolate a sources problem include swapping the source with another on the Tango Controller to see
if the problem stays with the Controller or follows the movement of the source. Also try swapping
IR emitter leads. Take a look at the source to ensure that no MUTE functions have been
accidentally activated.
No Keypad Activity (At All)
You are not getting power and command connectivity to the zone. Some of the possible causes are:
1. Zone connectors at the Controller are not secure.
2. Connector in the wall at keypad to Controller is not secure.
3. Wiring and connection directions not followed. Make certain the center two wires (DATA and GROUND)
are in the same orientation at the Controller and the keypad.
4. Connectors on keypad from Controller and speakers are reversed.
5. Keypad not recognized by system. Restart system.
Keypad Lights, No Sound
Power and command connectivity are getting to the zone. Check other zones and select each source to
determine if this is specific to the source or the room in general. If the problem is in a particular room then
there may be an issue with cabling to the speakers or it may be the keypad itself. If you get similar results for a
particular source in multiple zones then there may be an issue with the source equipment and you should check
to see that the selected source is ‘playing’. If every other zone is OK, check to make sure cables to the speakers
are secure and that you have tried to increase the volume level in the zone.

If you connect a keypad while the Controller is on you must restart the Controller for
that keypad to become active.
