Bodypack Transmitter

• Components:
• Power Indicator: Lights up when the unit is powered on.
• Digital Display: Shows current channel and frequency.
• Frequency Modulation Button (SET): Used to adjust frequencies and pair with the receiver.
• AA Battery Installation Box: Holds two AA batteries (not included).
• Antenna: Transmits the wireless signal.
• Switch: Power on/off switch for the bodypack.
• Audio Input (MIC): Connects to the lavalier or headset microphone.

Setup

1. Connect Antennas: Screw the two included antennas into the ANT A+B and ANT C+D ports on the rear of the receiver. Ensure they are securely fastened and positioned vertically for optimal signal reception.
2. Power the Receiver: Connect the power adapter to the DC 12-15V 500mA power input on the receiver and plug it into a power outlet. Press the Power button on the receiver's front panel to turn it on.
3. Install Batteries in Bodypacks: Open the battery compartment on each bodypack transmitter and insert two AA batteries, observing the correct polarity. Close the compartment securely.
4. Connect Microphones to Bodypacks: Plug the lavalier or headset microphone into the MIC input jack on each bodypack transmitter.
5. Power On Bodypacks: Turn on each bodypack transmitter using its power switch. The bodypack will automatically attempt to pair with the receiver.
6. Initial Pairing (Automatic): When a bodypack is powered on, it will automatically match a channel on the receiver. The receiver's display for that channel will show the corresponding frequency and signal indicators (RF/AF).

Operating Instructions

1. Volume Adjustment: Use the individual volume control knobs (Mic A, Mic B, Mic C, Mic D) on the receiver's front panel to adjust the output level for each microphone.
2. Signal Monitoring: The LCD display on the receiver shows the RF (Radio Frequency) and AF (Audio Frequency) signal indicators. A stable RF signal indicates a strong wireless connection, while the AF signal indicates audio input.
3. Wireless Range: The system offers an operating distance of up to 300ft (approximately 90 meters) in open space with a clear line of sight. Environmental factors such as walls and other wireless devices may affect the range.

Frequency Adjustment and Pairing

The system features 4x50 adjustable frequency groups (510-590MHz) to prevent interference. If you experience interference or need to change a channel:

1. Adjust Frequency on Bodypack: With the bodypack powered on, open the battery compartment. Press the SET button inside the compartment to cycle through available frequencies. The digital display will show the new frequency.
2. Locking the Frequency: To lock the frequency on the bodypack and prevent accidental changes, press the SET button and the Power button on the bodypack simultaneously. Dotted lines will appear on the bodypack's screen, and a lock icon will appear on the corresponding channel on the receiver's display, indicating the screen is locked. Repeat the process to unlock.
3. Automatic Pairing: The system is designed for automatic pairing. After adjusting the frequency on the bodypack, the receiver should automatically detect and sync with the new frequency. Ensure the bodypack is within range of the receiver during this process.

Connection Options

The receiver offers flexible connection options to integrate with various audio systems:

• 6.35mm (1/4") TRS Mix Output: Use the included 6.35mm audio cable to connect the MIX OUT port to the audio input of your soundbar, home receiver, speaker, or mixer for a combined output of all four microphones.
• XLR Balanced Outputs: For individual control and higher fidelity, connect the BAL-A, BAL-B, BAL-C, and BAL-D XLR outputs to the corresponding XLR inputs on a professional audio mixer or sound console.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the receiver and bodypack transmitters. Do not use liquid cleaners or solvents.
• Battery Care: Remove batteries from bodypack transmitters if the system will not be used for an extended period to prevent leakage.
• Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures.
• Antennas: Handle antennas carefully to avoid bending or breaking.

Troubleshooting

No Sound Output:

• Ensure the receiver is powered on and connected to your audio system.
• Check that the bodypack transmitters are powered on and have fresh batteries.
• Verify that the receiver's volume controls are not set to minimum.
• Confirm that the microphones are securely plugged into the bodypacks.
• Check the audio cables connecting the receiver to your sound system.

Interference or Dropouts:

• Adjust the frequency of the bodypack transmitter (refer to 'Frequency Adjustment and Pairing' section).
• Ensure the receiver antennas are properly positioned and unobstructed.
• Move the receiver closer to the bodypack transmitters.
• Check for other wireless devices operating on similar frequencies nearby.
• Avoid placing the receiver near metal objects or other electronic equipment that may cause interference.

Bodypack Not Pairing:

• Ensure the bodypack and receiver are both powered on.
• Check the battery level of the bodypack.
• Try adjusting the frequency on the bodypack to find an available channel.
• Ensure the bodypack is within the operating range of the receiver.
