Setup Guide

1. Connecting the Receiver

Connect the provided power adapter to the DC9V-12V power input on the rear of the wireless receiver. Plug the power adapter into a suitable power outlet.

For audio output, connect the 1/4" audio cable from the "MIX OUT" port on the receiver to the MIC input jack of your amplifier, PA system, or karaoke machine. Ensure it is plugged into the MIC jack, not the AUX jack.

Operating Instructions

Microphone Volume Control

Each dynamic microphone features its own independent volume control on the receiver. This allows you to balance the vocal levels as desired for optimal sound. Adjust the volume knobs for Mic A and Mic B separately on the receiver's front panel.
