MacBook picking up sounds from the Internal Microphone - How to Stop

While using a USB Turntable, and recording a Vinyl album, I am picking up any sound in the room, (Talking etc.) How can I stop this from happening?

Also, I am running Mac OS Mohave 10.14.6 and Audacity 2.2.3

If Audacity is set to get input from the USB turntable you should get no sound from the internal microphone.

What are your settings in the Device Toolbar?

I have NO Options except the Built-In Microphone as my TurnTable is Core Audio.

See the attached.

Your help is greatly appreciated!


Also wanted to state… I’ve been told by the Vendor(IONAUDIO) that my Numark TTUSB turntable is a class compliant device. I don’t know if this changes anything?
