Installing The SoundStructure C16, C12, C8, And SR12

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.

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.
