Tango Series Audio Controllers
3. Check to see that the IR emitter lead is securely fastened to the IR receiver on the source component and
that you have the lead plugged into the appropriate IR output jack. These can sometimes be mismatched.
When a keypad command is received and communicated to the source device, there is a LED that lights
on the front of the 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 IR emitter lead.
When testing 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 Controller to see if the problem stays with the Controller or
follows the movement of the source. Also try swapping IR emitter leads.
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.
Check the Following:
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. 75).
