What’s Included?

• 4-channel wireless receiver
• Four wireless handheld microphones
• Four 9V batteries (one per microphone)
• Two antennas for optimal signal reception
• 1/4" (6.35mm) audio cable
• Power adapter

Step 1: Setting Up the Receiver

1. Attach the antennas to the back of the receiver at the labeled Antenna 1 & 2 and Antenna 3 & 4 ports.
2. Extend the antennas upward for better reception.
3. Plug in the power adapter and turn on the receiver.
4. The LCD displays on the receiver should light up, indicating power and connectivity status.

✅ Optional: If you want to rack-mount the receiver, use the included screw holes to secure it into a 1U rack.

Step 2: Installing the Batteries in the Microphones

1. Unscrew the bottom cap of each microphone.
2. Insert a 9V battery, ensuring the positive and negative terminals match.
3. Screw the cap back on securely.
4. Turn on each microphone using the ON/OFF switch.

Matching Microphone Frequencies

Each microphone is pre-assigned to a specific frequency that corresponds with a channel on the receiver.

• Ensure the frequency displayed on the microphone matches the channel on the receiver.

Step 3: Connecting the Receiver to a Sound System

Option 1: Connecting to a Powered Speaker

If you're using a powered speaker (such as the Rockville BPA8):

1. Use the included 1/4" audio cable.
2. Plug one end into the “Mix Output” on the receiver.
3. Plug the other end into the 1/4" mic input on the powered speaker.
4. Turn up the microphone volume on the receiver.
5. Adjust the speaker volume accordingly.

🎤 Test each microphone by speaking into it to ensure the signal is coming through.

Option 2: Connecting to a Mixer for Larger Setups

For a larger audio system with a mixer and passive speakers:

1. Use XLR cables to connect the receiver to the mixer.
2. Take two XLR cables and plug them into the Channel 1 & 2 and Channel 3 & 4 outputs on the receiver.
3. Plug the other ends into two separate input channels on the mixer (e.g., Channels 1 and 2).
4. Turn on the mixer and power amp.
5. Raise the channel volumes on the receiver and the gain knobs on the mixer.
6. Adjust the EQ, effects, and faders on the mixer for better sound control.

✅ With this setup, you can:

• Assign Microphones 1 & 2 to one channel and Microphones 3 & 4 to another.
• Use EQ settings and effects on the mixer for better vocal clarity.

Step 4: Optimizing Your Wireless Microphone System

Adjusting Volume and Gain

• Each microphone has its own volume knob on the receiver.
• Use the gain knob inside the microphone (by unscrewing the bottom cap) to boost the signal if needed.

Operating the Microphones

• Each microphone has an ON/OFF switch and a MUTE switch.
• Always ensure the microphone is switched to ON (not just MUTE) for sound transmission.

Step 5: Wireless Range & Performance

📡 The RWM4200VH offers excellent wireless range:

• Indoors: 100 - 200 feet
• Outdoors: 65 - 165 feet

✅ Best Practices for Strong Signal Reception:

• Keep the antennas extended and upright.
• Avoid placing the receiver near Wi-Fi routers or other wireless devices to minimize interference.
• Ensure line-of-sight between the microphones and receiver for the best signal strength.
