Zone Connection Problems
If there is wall power and both the source components and the Controller seem to be powering up OK, but one or more of the
zones are not working, there may be a problem at the individual zone or with the cabling connecting to the zone. Begin by checking
each zone keypad for functionality by pressing the desired source button. The LED should light red next to the source on the KP-4e
keypads or should “wake up” with a screen menu on the touch panel keypad.
Dead Zones
There is power and the source devices and the Tango Controller seem to be powering up OK, but one or more of the zones are not
working.
Check each zones keypad for functionality by pressing the desired source button. The LED should light Red next to the source.
LED Does Not light
You are not getting power and command connectivity 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 your
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.
Possible Causes:
Zone connectors at Tango Controller are not secure.
Connector at Keypad to Tango Controller is not secure.
Wiring standard not followed. Make certain the center two wires are in the same orientation at the Tango Controller and the
keypad. They may have been inadvertently reversed during the installation.
Input and output connectors on keypad are reversed.
Keypad not recognized by system. Restart system.
Source Connections
Problems in source cabling display some of the following characteristics.
The source cannot be heard in any zone.
The source doesn’t seem to respond to keypad commands.
Ensure that the sources LINE OUT connections are connected to the Tango Controllers LINE IN connections for the correct device.
Check to see that the IR emitter lead is securely fastened to the IR receiver on the audio source and that you have the lead plugged
into the appropriate IR output jack (FIG. 103).
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.
NOTE:
If you connect a keypad while the Controller is on you must restart the Controller for that keypad to become active.
