CDM-4000BT: using the microphone inputs
The Gemini Sound CDM-4000BT DJ player has two microphone inputs but only one volume knob. That means both microphones are always live and share the same level. You can't set a separate volume for each mic from the controller on this model.
If you need separate volume for each mic
Use microphones with their own built-in volume control, like the ones in our GMU series. Each mic sets its own level, so you can balance the two independently without relying on the CDM-4000BT.
