4. Setup Instructions

4.1. Receiver Connection

  1. Positioning: Place the receiver unit in a central location, away from potential sources of interference (e.g., Wi-Fi routers, large metal objects). The unit is rack-mountable and fits a standard 19" rack.
  2. Antenna Connection: Connect the provided antennas to the "Antenna A" and "Antenna B" ports on the rear of the receiver. Ensure they are securely tightened.
  3. Power Connection: Connect the AC-DC power adapter to the receiver's power input port and then plug it into a suitable power outlet. Do not power on the unit yet.
  4. Audio Output:
    • For individual microphone outputs, connect XLR cables from the receiver's "BALANCED XLR" outputs (A, B, C, D, etc.) to your mixer or audio interface.
    • For a combined output, connect the supplied 1/4" audio cable from the receiver's "MIX output" to your mixer or audio interface.

4.2. Microphone Battery Installation

  1. Locate the battery compartment on the underside of each gooseneck microphone base.
  2. Open the compartment and insert two AA batteries, ensuring correct polarity (+/-).
  3. Close the battery compartment securely.

4.3. Powering On and Synchronization

  1. Power On Receiver: Press the power button on the receiver unit. The LCD display should illuminate.
  2. Power On Microphones: Press the power switch on each gooseneck microphone base.
  3. Automatic Synchronization: The system features automatic transmitter setup. The receiver and microphones will typically synchronize their channels automatically upon power-up. If manual synchronization is required, refer to the specific instructions on the receiver's front panel or the microphone's IR window for pairing procedures. Ensure the microphone's IR window is facing the receiver's IR sensor during synchronization.

5. Operating Instructions

5.1. Microphone Usage

  • Position the gooseneck microphone approximately 15-30 cm (6-12 inches) from the speaker's mouth for optimal sound capture.
  • Ensure the microphone is powered on and synchronized with the receiver. The microphone's display will show its active channel.

5.2. Volume Control

  • Receiver Volume: Adjust the individual volume knobs on the receiver's front panel for each microphone channel to achieve the desired output level.
  • Microphone Volume: Some microphones may have a local volume control on their base. Use this for fine-tuning the input sensitivity before it reaches the receiver.

5.3. Channel Selection and Interference Management

  • Each channel offers 100 selectable frequencies. If you experience interference, you can change the frequency of a specific microphone and its corresponding receiver channel. Refer to the receiver's manual for detailed instructions on manual frequency selection.
  • The system is designed to allow up to 20 units (160 microphones) to be used simultaneously, provided appropriate frequency planning is implemented to avoid inter-channel interference.

6. Maintenance

  • Cleaning: Use a soft, dry cloth to clean the receiver and microphone surfaces. Avoid using liquid cleaners or solvents, as they may damage the finish or internal components.
  • Battery Replacement: Replace AA batteries in the microphones when the low battery indicator appears on the microphone's display or when audio quality degrades. Always use fresh, high-quality batteries.
  • Storage: When not in use for extended periods, remove batteries from the microphones to prevent leakage. Store the system in a cool, dry place, away from direct sunlight and extreme temperatures.
  • Antenna Care: Ensure antennas are not bent or damaged. Damaged antennas can impair wireless performance.
