The microphone audio is completely isolated from all other grounds. The three sound card audio signals are isolated using three audio transformers. The computer is isolated using, three DPDT relays, three opto-isolators and a isolating DC to DC converter. A high grade DC blocking capacitor is on the sound card to mic. output for use with radios that are designed for use with amplified or electret microphones. The relays provide adequate current and voltage capability to switch tube rigs. The relays also provide automatic switching between sound card audio, transmit muting and our mic. override and mic. interrupt features.
