Port Characteristics
Universal (Bi-directional) jacks are supported on ports C (input only) and F. Port A is birdirectional
also. Ports A and B are designed to drive 32 ohm (nominal) headphones or a 10K (nominal) load.
Line Level outputs are intended to drive an external 10K load (nominal) and an on board shunt resis-
tor of 20-47K (nominal). However, applications may support load impedances of 5K ohms and
above. Input ports are 50K (nominal) at the pin.
