5. Setup
5.1. Battery Installation
The ULXD2 transmitter uses a Shure Lithium-Ion rechargeable battery (SB900B). Ensure the battery is fully charged before first use.
- Unscrew the lower half of the transmitter handle to expose the battery compartment.
- Insert the Shure Lithium-Ion battery into the compartment, ensuring correct polarity.
- Screw the handle back on securely.
5.2. Powering On and Off
- To power on, press and hold the power button until the display illuminates.
- To power off, press and hold the power button until the display turns off.
5.3. Linking to a Receiver
The ULXD2 transmitter must be linked to a compatible Shure ULX-D receiver to operate. Refer to your ULX-D receiver's manual for detailed linking instructions. Generally, this involves:
- Performing a scan on the receiver to find an open frequency.
- Syncing the transmitter to the receiver via infrared (IR) sync. Align the IR windows on both devices and initiate the sync process from the receiver.
6. Operating Instructions
6.1. Display and Navigation
The ULXD2 features an LCD display and navigation buttons (Enter, Exit, Up, Down) to access and adjust settings. The display shows critical information such as frequency, group/channel, battery status, and gain settings.
6.2. Gain Adjustment
The ULXD2 transmitter utilizes Shure Gain Ranging, which automatically optimizes the system's dynamic range. This feature typically eliminates the need for manual gain adjustments on the transmitter itself. For fine-tuning audio levels, adjustments should primarily be made on the connected ULX-D receiver or mixing console.
6.3. Encryption
The ULXD2 supports AES 256-bit encryption for secure transmission. Encryption is enabled and managed through the ULX-D receiver. When encryption is active, the transmitter and receiver must be properly paired with the same encryption key. Consult your receiver's manual for details on enabling and managing encryption.
7. Maintenance
7.1. Cleaning
- Use a soft, dry cloth to clean the exterior of the transmitter.
- Do not use abrasive cleaners or solvents, as they may damage the finish or internal components.
- For the microphone grille, gently remove any debris. The Beta 58A grille can often be unscrewed for cleaning the foam windscreen inside.
7.2. Battery Care
- Always use genuine Shure Lithium-Ion batteries for optimal performance and safety.
- Charge batteries using a compatible Shure charger (sold separately).
- Store batteries in a cool, dry place when not in use.
- If the transmitter will not be used for an extended period, remove the battery.
8. Troubleshooting
If you encounter issues, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No audio output | Transmitter not powered on; Not linked to receiver; Receiver muted; Incorrect frequency. | Ensure transmitter is on; Perform IR sync with receiver; Check receiver mute status; Verify transmitter and receiver are on the same frequency. |
| Intermittent audio or dropouts | Interference; Transmitter too far from receiver; Obstructions; Low battery. | Perform a new frequency scan on receiver; Reduce distance between transmitter and receiver; Ensure line-of-sight; Replace or recharge battery. |
| Poor sound quality (distortion, noise) | Input level too high; RF interference; Damaged microphone capsule. | Adjust gain on receiver; Rescan for clear frequency; Inspect microphone capsule for damage. |
| Transmitter display not working | Low or dead battery; Transmitter fault. | Replace or recharge battery; If problem persists, contact Shure support. |
