2. Connecting the Receiver

The receiver features a 6.35mm (1/4 inch) jack for connection to compatible audio devices.
- Insert the receiver directly into the microphone input (MIC IN) of your karaoke machine, amplifier, mixer, or powered speaker.
- If your device has a 3.5mm (1/8 inch) microphone input, use the included 3.5mm adapter.
- Ensure the host device's volume is set to a low level before connecting to avoid sudden loud noises.

2. Microphone Usage

- Hold the microphone approximately 2-6 inches from your mouth for optimal sound pickup.
- The microphone features a unidirectional polar pattern with 180° pickup for high-quality sound, effectively capturing audio from the front while minimizing background noise.
- Adjust the volume on your connected audio device (karaoke machine, amplifier, etc.) to achieve the desired sound level. The microphones themselves do not have volume controls.
- The system offers a stable signal with an operating range of up to 100 feet (line of sight).

- Maintain a clear line of sight between the microphones and the receiver for best performance. Obstacles can reduce the effective range.
- Avoid placing the receiver near strong electromagnetic interference sources.
