    Does anyone know the properties (like voltage, ampage, impedance, etc.) of standard audio inputs, i.e. phonos, jacks, etc.? Thankyou.

    Audio inputs are usually capacitive coupled, with an input resistor of 47K. That can be higher, up to 100K. The signal level is about 1.25 VRMS. The input connectors have no inherent impedance at audio frequencies. Any connector that carries the shielding works fine - even BNC's if you want really excellent connections.
