3. Connecting to an Audio Device

The receiver can be connected to devices with either a 3.5mm or 6.35mm microphone input jack.

Identify the microphone input jack on your audio device (e.g., PA system, amplifier, mixer).
If your device has a 3.5mm mic jack, plug the receiver directly into it.
If your device has a 6.35mm mic jack, attach the included 6.35mm adapter to the receiver, then plug the receiver with the adapter into the 6.35mm mic jack.
Ensure the audio device's volume is set to a low level before turning it on to prevent sudden loud noises.
