Apache Labs ANAN-G2 - 2.4 Rear Panel Connections

ANAN-G2 Manual Page 11 of 35
Use the “audiocheck” desktop app to test your microphone connection.
The microphone carries both microphone audio and PTT signals. Your DSP program (for example
piHPSDR or Thetis) has controls to select how the signals are connected.
• PTT, if enabled, is achieved by connecting the PTT input to Ground
• A DC bias for the audio signal – needed by condenser “electret” microphones – can also be
selected by your client app.
We are aware that some, but not all, PC headsets suffer loss of signal level when connected, because
of the PTT connection. Using an external cable to “break” the wire to the ring will eliminate this.
