HI,Is anyone using the iBox W2IHY in the microphone path of an Anan 200D? I connected it according to the diagram shared by Julius, and something's wrong. The signal is rough and the potentiometer in the iBox doesn't work. Perhaps the audio signal should be sent through the sound card?

Re: iBOX W2IHY
If you post a picture of the wiring diagram you are using that would help.
Also, what are you plugging into the input of the iBox?

Never mind those questions as they were answered in your other topic:

With the Apollo interface you should definitely not be using the iBox. If you are running the latest version of Thetis (what version are you running?) then you should be using the relatively new "cmASIO" feature to accept audio from the Apollo over USB or Thunderbolt (whichever you have).
The directions for setting up cmASIO are in a PDF file that can be found in the same directory as thetis.exe, which is C:\Program Files\OpenHPSDR\Thetis.
Make certain that the Apollo is running at 48 KHz sampling rate and that its buffer size is set to 64.
Once this is running successfully then we can discuss a much nicer way of attaching your PTT footswitch rather than use the rear panel accessory connector.
We need to sort out the interface problem first, then see if this is still a problem.qst wrote: Fri Oct 31, 2025 8:55 am Hi,I started configuring the TX on the Anan 200D. I have a dynamic microphone connected to the Apollo Universal Audio, and the microphone signal enters the front-panel jack through a transformer. I connected the PTT to the rear DB25 socket on pin 13, as described in the manual. When I activate the PTT with the footswitch, a low power level appears on the screen for a moment, and I hear a clicking sound in the headphones. After that, the modulation is clear. I've set the MIC and ALC levels. When I press the PTT, there's no noise on the TX filter bar. But I activate transmit by pressing the MOX button. On the Thetis, the noise is clearly audible and I can see it on the TX filter bar. However, activating the MOX button doesn't cause any clicking sound in the headphones. What else can I do to avoid this clicking sound when I press the PTT? The correspondents hear it when I start talking?
