 Installing The SoundStructure C16, C12, C8, And SR12
2 - 19
When the logic output is set low (off), the transistor will turn off and an open 
circuit will be created between the logic output and the chassis ground 
preventing any flow of current as shown in the following figure.
See Logic Examples for information on how to wire the logic interface for 
common logic applications.
Powering Up The System
Connect the AC power line to a grounded AC power main when ready to 
power the device and plug the other end securely into the rear of the 
SoundStructure unit. Ensure the plug is securely inserted as shown in the 
following figure. Upon insertion there will be some initial resistance - continue 
pushing until the power cord is plugged in.
The SoundStructure units require an AC voltage supply in the range of 90-250 
VAC and 50-60 Hz. Power should be applied after any plug-in cards are 
installed.
As there is no power switch on the SoundStructure devices, once power is 
connected, the system will begin the boot-up process.
