Setup

1. Initial Charging

Before first use, fully charge both the U45 Transmitter and Receiver using the provided dual USB-C charging cable. Connect the cable to a standard USB power adapter (not included). A full charge takes approximately 2 hours and provides up to 5 hours of battery life. A 10-minute charge can provide 1 hour of use.

2. Connecting the Transmitter

The U45 Transmitter features a balanced XLR input jack. Connect the transmitter directly to your audio interface, mixer, or other audio source. If your source has a 1/4" TS output, use the included 1/4" TS adapter to connect it to the transmitter's XLR input.

3. Powering On and Channel Selection

Turn on both the transmitter and the receiver. The U45 system offers 6 selectable channels. To find the best available channel, hold the receiver's channel button for 3 seconds to initiate Channel Scan mode. The receiver's LED will flash during scanning and then remain steady on the optimal wireless channel. Manually set the transmitter's channel to match the receiver's selected channel.

Operating Instructions

True Diversity Technology

The U45 system incorporates true diversity technology, utilizing dual antennas on the receiver. This feature allows the receiver to constantly scan and select the strongest signal from the transmitter, effectively preventing dropouts and ensuring a stable, uninterrupted audio feed. This is crucial for reliable performance in dynamic environments.

Multi-Receiver Monitoring

One U45 Transmitter can send the same audio mix to multiple U45 Receivers simultaneously. This feature simplifies group monitoring for bands or multiple performers, allowing everyone to receive the same mix from a single source. Ensure all receivers are set to the same channel as the transmitter for seamless operation.

5.8 GHz Frequency Band

The U45 system operates on the 5.8 GHz frequency band. This band is generally less crowded than the 2.4 GHz band, which is commonly used by Wi-Fi and other wireless devices. Operating in 5.8 GHz helps to avoid interference, providing a cleaner and more reliable signal for your in-ear monitoring needs, especially in environments with multiple wireless systems.

Cleaning

Clean the units with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure no moisture enters the ports or openings.

Troubleshooting

No Sound or Intermittent Audio

  • Check Power: Ensure both the transmitter and receiver are powered on and have sufficient battery charge.
  • Match Channels: Verify that the transmitter and receiver are set to the same channel. Use the channel scan function on the receiver to find the clearest channel.
  • Volume Levels: Confirm that the volume on the receiver is turned up and that the audio source connected to the transmitter is sending a signal.
  • Cable Connections: Ensure all cables (XLR, TS adapter, headphones) are securely connected.
  • Range: The system has a solid RF connection over a 100 ft (30.5 m) distance. Ensure you are within this range.

Interference

  • Change Channel: If you experience interference, perform a channel scan on the receiver to find a less congested channel and match the transmitter accordingly.
  • Minimize Obstructions: Large metal objects or thick walls can interfere with wireless signals. Try to maintain a clear line of sight between the transmitter and receiver.
  • Distance from Other Devices: While the 5.8 GHz band is less crowded, keep the units away from other high-power wireless devices if possible.
