Delta Series Audio Controllers
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 Delta 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 Delta 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.
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 Delta Controller are not secure.
2.
Connector in the wall at keypad to Delta 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 Delta 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.
