4. Setup
Follow these steps to connect your VOYZ VZ-638G microphone to your audio system:
- Connect the XLR Cable: Take the provided 15ft XLR to 1/4'' audio cable. Connect the XLR (3-pin) end of the cable firmly into the XLR port at the base of the microphone. Ensure it clicks into place securely.
- Connect to Audio Input: Plug the 1/4'' (6.35mm) jack end of the cable into the microphone input port of your karaoke machine, mixer, or audio interface. This port is typically labeled "Mic In" or has a microphone icon.

5. Operating Instructions
Using your VOYZ VZ-638G microphone is straightforward:
- Turn On the Microphone: Locate the ON/OFF switch on the microphone body. Slide the switch to the "ON" position.
- Adjust Volume: Gradually increase the volume on your connected audio device until the desired sound level is achieved. Avoid setting the volume too high initially to prevent feedback or damage to speakers.
- Optimal Usage: For best vocal performance, hold the microphone approximately 2-6 inches (5-15 cm) from your mouth. Speak or sing directly into the grille. The unidirectional pattern helps to capture your voice clearly while minimizing ambient noise.
- Turn Off After Use: When finished, slide the ON/OFF switch to the "OFF" position before disconnecting the microphone or turning off your audio equipment. This prevents sudden loud noises and protects your equipment.

- Storage: Store the microphone in a cool, dry place away from direct sunlight and extreme temperatures. Keep it protected from dust and physical impact.
- Cable Care: Avoid sharp bends or kinks in the cable. Coil it loosely when storing to prevent damage to the internal wiring.
