Step-by-Step Instructions

1. Connect Power to the Receiver

2. Insert the included batteries into the battery compartment.
3. Replace and twist the end cap back on.
4. Repeat for both microphones.

3. Connect to a Powered Speaker

1. Before making connections, ensure your speaker’s volume levels are turned all the way down.
2. Raise the receiver’s antennas for optimal wireless performance.
3. Use the included 1/4" cable:
   • Plug one end into the Mix Out (1/4" output) on the receiver.
   • Plug the other end into the Mic Input (1/4") on your powered speaker.
4. Power on the receiver. The digital display will light up.
5. Gradually raise the volume levels on both the speaker and the microphones (using the volume knobs on the receiver).

4. Wireless Range

• Indoors: up to 250–350 feet
• Outdoors: up to 200–300 feet
• You can move freely within this range without losing sound quality.

5. Connect to a Mixer (Optional)

For more sound control (EQ, effects, etc.), you can connect the RWM72U system to a mixer instead of directly to a speaker.

Option 1: Using the included 1/4" cable

• Connect the Mix Out (1/4") on the receiver to a 1/4" input on the mixer.

Option 2: Using XLR outputs for more control

1. Connect XLR cables from the Balanced A and Balanced B outputs on the back of the receiver.
2. Plug them into channels 1 and 2 of your mixer.
3. Power on the mixer and raise the channel faders.
4. Adjust the main left/right faders and microphone volumes as needed.

Troubleshooting & FAQs

Q: My microphone isn’t producing sound. What should I check?

• Ensure the microphone switch is turned on.
• Confirm the receiver and speaker/mixer are powered on.
• Check that the volume knobs on both the receiver and speaker/mixer are turned up.
• Verify that the microphone and receiver are on the same frequency (displayed on the LED).

Q: The range seems shorter than expected.

• Make sure both receiver antennas are fully raised.
• Avoid obstructions like walls or metal objects between the microphone and receiver.
• Replace batteries if they are low.

Q: Can I use both microphones at once?

• Yes, the receiver supports both microphones simultaneously on separate channels.
