Power Up Process:
When a +3 to +12V sig-
nal is sensed at the trigger input of either
of the 1/8” TS connectors, or the 3-pin
connector, the rear panel master trigger
indicator LED will change from off to blue.
All the zones will be held in standby for
about 2 seconds until the power supplies
have fully charged and performed their
self-tests. During this short process, the
front panel Power and Protection LEDs
will be red. Once this is complete, the
Power LED will turn blue and the Protec-
tion LED will turn off.
Power Down Process:
As soon as a
Zero Volt signal is sensed at the master
trigger inputs, all zones will be muted and
placed in standby, and the rear panel mas-
ter trigger LED will change from blue to
off. The front panel Power LED will remain
on, as the main power supplies will be still
energized.
If the master trigger Inputs remain at
Zero Volts for 2 seconds, the main power
supplies will shut off; the front panel Pow
-
er LED will change from blue to red. The
Protection LED will flash red once during
the power-down process.
The trigger input is biased towards
ground. This keeps the unit in standby
when nothing is connected.
If you are not using master triggering or
the Ethernet connection, then you
must
install a short wire link from the +12V
output to the trigger input. To put the unit
into standby, remove the link.
Wire Link
To trigger ON with a contact closure:
Connect the contact closure between
+12V and Trigger Input
To trigger OFF with a contact closure:
Connect a 1 kΩ resistor b12V
and Trigger Input
Connect the contact closure between
Trigger Input and GND
To use an external 12V trigger:
Connect the external ground to The
Director GND
Connect the ex12V output
voltage to The Director Trigger Input
