- Connect to Audio System:
- Using 1/4" Mix Output: Connect the provided 1/4" output cable from the MIX OUT port on the receiver to the input of your amplifier, mixer, or PA system. This combines the audio from both microphones into a single output.
- Using XLR Outputs: For separate control of each microphone, connect XLR cables (not included) from BALANCED-1 (Mic A) and BALANCED-2 (Mic B) to individual XLR inputs on your mixer.
- Connecting to TV (via Amplifier): If connecting to a TV, ensure your TV's audio output is connected to an audio amplifier, and then connect the FIFINE K040 receiver to the amplifier as described above.
