Title: Converting David Clark Headset Analog Output to USB

[Sammy_123]

Hello everyone,

I have a David Clark (H9940) headset with the following pin configuration:

• RT ear
• Ground
• LT ear
• Sens
• Mic Hi
• Mic Low
• Shield

I want to convert the analog output of this headset to a USB connection. From my research, I understand that I need an ADC board like the Behringer U-Control UCA222 to accomplish this.

My plan is to wire the pins from the headset to RCA plugs that can connect to the UCA222. However, I'm looking for some guidance on the specifics:

1. How should I wire the RT ear, LT ear, and ground to the RCA plugs?
2. How do I handle the microphone signals (Mic Hi, Mic Low, and Shield) in this setup?
3. Are there any additional components or considerations I should be aware of to ensure proper functionality?

Additionally, I know that the headset requires external voltage and impedance control for the microphone to function correctly. Could someone provide details on:

1. The required voltage levels for the microphone input.
2. How to implement impedance control in this configuration.

Any advice, wiring diagrams, or tips from those who have done a similar conversion would be greatly appreciated!

Thanks in advance for your help!
