5. Installation
5.1. Installation de la batterie
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.
- Revissez fermement la poignée.
5.2. Mise sous tension et hors tension
- Pour allumer, appuyez sur le bouton d'alimentation et maintenez-le enfoncé jusqu'à ce que l'écran s'allume.
- Pour éteindre, maintenez enfoncé le bouton d'alimentation jusqu'à ce que l'écran s'éteigne.
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. Mode d'emploi
6.1. Affichage et 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. Ajustement des gains
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. Chiffrement
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. Entretien
7.1. Nettoyage
- Utilisez un chiffon doux et sec pour nettoyer l'extérieur de l'émetteur.
- N’utilisez pas de nettoyants abrasifs ni de solvants, car ils pourraient endommager la finition ou les composants internes.
- For the microphone grille, gently remove any debris. The Beta 58A grille can often be unscrewed for cleaning the foam windscreen inside.
7.2. Entretien de la batterie
- Always use genuine Shure Lithium-Ion batteries for optimal performance and safety.
- Charge batteries using a compatible Shure charger (sold separately).
- Rangez les piles dans un endroit frais et sec lorsqu'elles ne sont pas utilisées.
