Introduction

The Rockville RWM4401UH is a four-channel wireless handheld microphone system, ideal for live performances, DJ events, houses of worship, karaoke, and more. It features four color-coded wireless mics, a four-channel receiver, and both quarter-inch and XLR output options for seamless audio integration.

This guide will walk you through:

• Setting up the receiver and microphones
• Connecting to a powered speaker
• Expanding your setup with a mixer
• Maximizing signal range and performance

Step 1: Unboxing and Identifying Components

Inside the RWM4401UH package, you’ll find:

1. Four color-coded wireless microphones (Orange, Red, Green, Blue)
2. Four-channel receiver
3. Four pairs of AA batteries (one for each mic)
4. Two antennas (for the receiver)
5. Quarter-inch (1/4") cable (for speaker connection)
6. Power adapter (for the receiver)

Step 2: Setting Up the Receiver

1. Attach the antennas:
   • Locate the two antenna ports on the back of the receiver.
   • Screw in the antennas securely.
   • Adjust them to a V-shape for optimal signal reception.
2. Connect the power supply:
   • Plug the female end into the “Power In” socket on the back of the receiver.
   • Plug the other end into a wall outlet.
3. Power on the receiver using the front-panel switch.

Step 3: Setting Up the Wireless Microphones

1. Open the battery compartment:
   • Press the pressure point on the back of the mic to slide down the clip.
   • Insert two AA batteries, making sure the negative (-) side faces the spring.
   • Slide the battery cover back on.
2. Turn on the microphone:
   • Flip the switch to ON—it should automatically pair with its designated channel.
   • The color coding ensures each mic pairs with the correct channel:
     • Orange → Channel 1
     • Red → Channel 2
     • Green → Channel 3
     • Blue → Channel 4
3. Mute function:
   • Set the switch to the middle position to mute the microphone.

Step 4: Connecting to a Powered Speaker

Using the Included Quarter-Inch Cable

1. Plug one end of the quarter-inch cable into the “Mic Mix” output on the back of the receiver.
2. Plug the other end into the quarter-inch input on your powered speaker.
3. Ensure the speaker’s volume is down before powering on.
4. Turn on the speaker and gradually increase the volume.
5. Raise the channel level on the receiver for the desired microphone.

Step 5: Expanding with a Mixer

For greater control over volume, EQ, and effects, connect the system to a mixer.

Using a Quarter-Inch Cable (Basic Mixer Setup)

1. Plug one end into the “Mic Mix” output on the receiver.
2. Plug the other end into a quarter-inch input on the mixer.
3. Adjust the microphone levels using the mixer’s volume faders.

Using an XLR Cable (Higher Quality Audio)

1. Plug an XLR cable into the "Mix XLR Output" on the receiver.
2. Connect the other end to an XLR input on the mixer.
3. Raise the volume fader and adjust EQ as needed.

Using Four XLR Cables (Independent Mic Control)

For full control of each microphone separately:

1. Use four XLR cables.
2. Plug each XLR into the individual mic outputs on the receiver.
3. Connect the other end to four separate channels on the mixer.
4. Raise the volume of each channel individually to mix the microphones separately.

Step 6: Maximizing Wireless Performance

• Keep the receiver at least 3 feet away from large metal objects or walls.
• Extend the antennas to a V-shape for optimal reception.
• Avoid placing multiple wireless systems close together to prevent interference.
• Ensure the microphones are within the operating range:
  • Indoors: 300–400 feet
  • Outdoors: 250–350 feet

Conclusion

The Rockville RWM4401UH is an easy-to-use and powerful wireless microphone system, perfect for live events, karaoke, and professional setups. Whether connected to a powered speaker or a mixer, it offers clear, interference-free audio with a strong wireless range.
