Impedance is 600ohm.
You will need to:
1. Connect three wires to Violent Orange/Orange Violent and Green Violent.
2. Jumper Orange Violent to Violent Green.
3. Connect the apropriate audio connector jack to Violent Orange and Green Violent.
4. Plug audio jack int Aux on sterio turn Aux volume 1/2 to start.
5. To page dial Feature 62. Or program on autodial button:
dial F*3, press key, dial F62.
What usually goes wrong in the above is whether the sterio has the ability to take two feeds. The Norstar sends a preamp signal only. DO NOT connect speakers or amplified circuits directly to Norstar you will damage the KSU.
