Balanced Audio VK-255SE - Manual (Page 6)

Operating the VK-255SE
Turning the VK-255SE On:
The power switch is located on the VK-255SE front panel. If VK-255SE was turned OFF
even for a short period of time, you should wait at least 30 seconds before turning it back
ON. This precaution will minimize the stress on internal components.
When you turn the unit ON, the VK-255SE will automatically go through a gentle power-on
sequence. At the end of a 10 second delay the unit will unmute and become operational.
Front Panel LED Indicators/ Remote Trigger Operation
When the VK-255SE is not connected to the external 12V Trigger line, its Blue ON indicator
will turn ON and OFF when the power switch is depressed.
When unit is connected to the external controller via the 12V Trigger line, the condition
of the LED indicators will depend on the state of that control line.
If the external controller is in OFF state (12V signal is not present), then the green Stanby
LED will light upon power switch activation. The unit will alternate between the
Standby and Off state every time the Power Switch is depressed.
When in its Standby mode, the unit will be controlled by the 12V Trigger line. When
that line issues the ON command (12V signal is present) the green Standby LED will go
out, and the blue ON LED will light.
