Input Signal: 3-20 volts @ less than 10 mA
Output Signal: 12 volts @ 100 mA
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 transi- tions 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-1 as you would expect.
The 12v Trigger Output jack is driven to a “high” state of 12 volts a few seconds after the SC-1 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 com- ponents, such as the Wisdom Audio SA-series of amplifiers. Each Wisdom Audio component has a short delay built into its DC trigger system to fa- cilitate 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.
8AC Mains Input, Switch and Fuse Assembly
A conventional, 15-ampere IEC standard power cord is used with the SC-1. A high quality AC mains cord is included with the product, although the use of the standardized IEC receptacle means that you may easily substi- tute another high quality AC mains cord if you wish.
Your new Wisdom Audio SC-1 has been safety-tested and is designed for operation with a three-conductor power cord. Do not defeat the “third pin” or earth ground of the AC power cord.
An AC mains switch is located just above to the power cord on the rear panel of the SC-1. This switch may be used to disconnect the unit from the AC mains without having to actually unplug the SC-1 from the wall outlet.
If you plan to be away for an extended period, or have any other reason to turn the SC-1 completely off, you may either unplug the SC-1 or you may use the AC mains switch.
Potentially dangerous voltages and current capabilities exist within your SC-1. Do not attempt to open any portion of the SC-1’s cabinet. There are no user-serviceable parts inside your SC-1. All service of this product must be referred to a qualified Wisdom Audio dealer or distributor.
