These 12v trigger jacks provide compatibility with a wide range of products to
facilitate remote turn-on and turn-off in systems. These 1/8” (3.5 mm) “mini-jacks”
allow other components to bring the SC-2 in and out of standby. Two such mini-
jacks are provided to allow “daisy-chaining” of this turn-on signal with other
components, including additional amplifiers.
The remote trigger input will be operated by any positive-polarity DC signal
between 3–20 volts (only a few milliamps are required), with tip polarity as shown
below
The DC Trigger Input has priority over the front panel switch. Therefore, if a trigger
voltage is present at this input connector, the unit will be forced on and the front
panel switch will be ignored. When the voltage transitions from high to low (off),
the unit will go into standby.
When there is no voltage present at the trigger input (either because the controlling
device is not sending, or because the plug is removed), the front panel switch will
operate the SC-2, as you would expect.
The 12v Trigger Output jack is driven to a “high” state of 12 volts a few seconds
after the SC-2 is turned on and can source as much as 100 mA of current at 12
volts. This signal may be used in turn to control other components, such as
additional Wisdom Audio SA-series amplifiers. Each Wisdom Audio component
has a short delay built into its DC trigger system to facilitate a staggered turn-on
sequence.
Your Wisdom Audio dealer can help you take advantage of these design features to
maximize your system’s convenience and versatility.
