When using a Wireless Receiver, such as the Wireless GO II, Wireless PRO, or Wireless ME, with USB connectivity (using a USB-C to USB-C or a USB-C to Lightning MFI cable), the 'dB' button does not impact the output gain to the USB device, such as a mobile device or computers.
When connected via USB, the Wireless Receiver act as a USB microphone and the gain is controlled by the recording software or DAW (Digital Audio Workstation) on the device.
The gain 'dB' adjustment on the Wireless Receiver solely affects the 3.5mm analogue output.
