Microphone/ Audio Interface Options

[WT4DX]

Tem,
I believe you are using the presonus quantum 2 thunderbolt unit? What are your thoughts regarding latency, etc. How about compared to a usb unit? I am installing a thunderbolt adapter on my pc which is backward compatible to thunderbolt 2 with an adapter cable I believe. There are some pretty good prices on the quantum 2 right now I see. I also like the Apollo solo thunderbolt 3. Just thinking about interface options.

Hi Joe,

I don't have the Q2 up and running yet, but the Thunderbolt cable should have a slight edge over the USB.

I'll give you more appropriate feedback once I've logged some time with it.

Thanks Bryan and Tem,
I’ve been looking over different options with audio latency in mind. I did look at some of the pcie options as well. If I do go another route, I will post so maybe helpful to others. Tem, I look forward to what you find with the quantum 2. The thunderbolt adapter I am installing is thunderbolt 4 so I know to go to any version below thunderbolt 3, I would need another adapter to connect to the 3 cable. Just some things to think about.

I'm still working on my station's audio solutions, and would a Bluetooth transmitter such as the Sennheiser below have any potential to cause RFI issues with the rigs that we run?

In general, 2.4 and 5 GHz devices are usually safe. For instance, there's typically no interference from a house full of Wi-Fi devices.

I tried to set up VAC audio today; after being unsuccessful getting rid of the ECHO on my SSB transmit signal using the TRS balanced input on the G2 with plain front.

I set up an M-Audio Air 192/6 sound interface. Microphone is a Neumann KMS -105 with the phantom power on.
Using Voicemeeter Banana. Virtual input using VB-Audio Voicemeeter VAIO. VAC1 setup MME, VM output, VM Input. Tried ASIO, VM ASIO, VM ASIO without improvement. Voicemeeter pull-down selections are confusing!

Receive audio is great. So is the microphone audio over the shack studio monitors. But the microphone audio is not reaching the transmitter.

What am I doing wrong? I feel so close to setting up virtual audio.

Thanks for any guidance!!

Torrey--please clarify your situation. Are you saying there is still echo? Or are you saying that there is no transmit audio at all?

First off, change your driver back to ASIO in VAC setup.

If the problem is no transmit audio at all, check that none of the VAC "override" options are enabled.

If you continue to struggle, please post screen shots of your Voicemeeter and VAC configurations, especially the main Voicemeeter UI.

I went back to ASIO in the Thetis setup. After rebooting Thetis, transmit function was restored.
I was distressed that the transmitted audio had a loud crackling background.
So I set the M-Audio Air 192/6 aside. I had a new unused Behringer U-Phoria UMC202HD on the shelf. I set it up. Glad to see that it used only ASIO drivers. I seems to work satisfactorily with Thetis and no crackling. Too soon to know how it sounds on the air. The record/play buttons do not appear to function now. Is that expected with VAC?
Otherwise things look good.

Tnx & 73 Torrey N9PY
