Introduction

The RWM90U Quad Wireless UHF Microphone System is perfect for live performances, DJ events, karaoke, conferences, and more. With four wireless microphones and a multi-channel receiver, this system gives you crystal-clear audio, long-range connectivity, and seamless integration with powered speakers or mixers.

This guide will walk you through:

• Basic setup and connections
• Using the microphones with a powered speaker
• Integrating the system with a mixer for advanced control

What’s Included

• RWM90U Four-Channel Receiver
• Four Wireless Microphones
• Batteries for Each Microphone
• Four Antennas for Optimal Signal Reception
• Quarter-Inch (1/4") Cable
• Power Supply
• Rack Mount Ears (1U) for Mounting in a Rack Bag or Stand

Step 1: Setting Up the Receiver

1. Attach the four antennas to the back of the receiver by screwing them in place.
2. Plug the power supply into the receiver and then into an electrical outlet.
3. Turn on the receiver using the power switch.

Your receiver is now ready to connect to speakers or a mixer.

Step 2: Setting Up the Microphones

1. Unscrew the end cap on each microphone to reveal the battery compartment.
2. Insert the included batteries into each microphone.
3. Screw the end cap back on securely.
4. Turn on each microphone and check that it corresponds with the frequency displayed on the receiver.

Each microphone operates on its own channel with a dedicated frequency for interference-free performance.

Step 3: Connecting to a Powered Speaker

For a simple and direct setup, you can connect the receiver to a powered speaker.

To connect to a powered speaker:

1. Take the included 1/4" cable and plug one end into the 1/4" mix output on the back of the receiver.
2. Plug the other end into the 1/4" input on your powered speaker (e.g., Channel 1 on the Rockville Titan 12).
3. Turn on the speaker and receiver.
4. Raise the channel volume on the speaker.
5. Increase the volume knobs for each microphone channel on the receiver.

Your microphones should now transmit sound through the powered speaker!

Step 4: Connecting to a Mixer for More Control

If you want greater sound customization, connect the system to a mixer before sending the audio to speakers.

To connect to a mixer using the 1/4" cable:

1. Take the included 1/4" cable and connect it to the Mix Output on the receiver.
2. Plug the other end into a channel input on your mixer.
3. Turn on the receiver and mixer.
4. Raise the volume levels on the receiver and the mixer.

To connect to a mixer using XLR cables (for individual channel control):

1. Use four XLR cables.
2. Plug the female end of each XLR cable into the balanced XLR outputs on the receiver.
3. Plug the male end of each XLR cable into separate channel inputs on the mixer.
4. Turn on the receiver and mixer.
5. Raise the volume levels for each channel on the receiver and mixer.
6. Adjust the gain, EQ, and effects on the mixer for optimal sound.
7. Raise the master volume faders on the mixer to hear the audio from connected speakers.

Now, you can adjust individual microphone levels, add effects, and shape the sound for professional use!

Step 5: Understanding Frequency and Range

Each microphone operates on its own frequency, which is displayed on the receiver’s LCD screen.

• Indoor range: Up to 300-400 feet.
• Outdoor range: Up to 250-350 feet.

Move freely without worrying about interference or dropouts!
