2. การตั้งค่า

2.1 ข้อกำหนดของระบบ

• This ULXD2/B58 transmitter requires a Shure ULXD4 receiver to form a complete operational wireless system.
• Ensure that the frequency bands of the transmitter and receiver match for proper system operation. This model operates in the G50 Band (470 – 534 MHz).

2.2 การติดตั้งแบตเตอรี่

• The transmitter operates on 2 AA batteries, which are included.
• Open the battery compartment, insert the batteries according to the polarity indicators, and close the compartment securely.
• The ULX-D system also supports intelligent rechargeable solutions for extended use and remote monitoring of battery life.

2.3 การจับคู่กับตัวรับสัญญาณ

To establish a wireless connection, the transmitter must be paired with a compatible ULXD4 receiver. Refer to the ULXD4 receiver's instruction manual for detailed pairing procedures. Generally, this involves synchronizing the transmitter and receiver via infrared (IR) sync to match their operating frequencies.

3. คู่มือการใช้งาน

3.1 การเปิด/ปิดเครื่อง

• To power on the transmitter, press and hold the power button until the display illuminates.
• หากต้องการปิดเครื่อง ให้กดปุ่มเปิด/ปิดค้างไว้จนกระทั่งจอแสดงผลดับลง

3.2 การใช้งานไมโครโฟน

The BETA 58A vocal microphone capsule is designed for professional vocal applications. Hold the microphone firmly, pointing the grille towards the sound source. Maintain an appropriate distance from the sound source to prevent feedback and ensure optimal audio quality. The microphone's polar pattern is unidirectional, meaning it primarily picks up sound from the front, reducing unwanted background noise.

คุณสมบัติขั้นสูง 3.3 ประการ

• AES 256-bit Encryption: The ULXD2/B58 supports AES 256-bit encryption for secure transmission, generating a randomized key for each use. This feature is crucial for applications requiring confidentiality.
• การตรวจสอบระยะไกล: When used with compatible Shure software (e.g., Wireless Workbench 6, SystemOn), battery life and charge status can be monitored remotely.

4. คุณสมบัติ

• Requires a ULXD4 receiver to complete the system. Ensure frequency bands match for proper operation.
• Handheld wireless transmitter compatible with ULX-D digital wireless systems.
• Includes an interchangeable Shure BETA 58A microphone cartridge.
• Features a rugged yet lightweight aluminum body and integrated antenna.
• Delivers uncompromising audio quality and RF performance.
• Incorporates AES 256-bit encryption for secure transmission.
• Offers advanced rechargeability options for professional sound reinforcement applications.
• Provides a 30 Hz–20 kHz range with flat frequency response (actual response is microphone dependent).

4.1 ประสิทธิภาพโดยรวมview

The ULX-D Digital Wireless system is designed to overcome common wireless challenges in professional environments.

6. การบำรุงรักษา

6.1 การทำความสะอาด

• Regularly wipe the exterior of the transmitter with a soft, dry cloth.
• For the microphone grille, gently remove any debris. The BETA 58A capsule grille can often be unscrewed for more thorough cleaning of the foam windscreen inside.
• หลีกเลี่ยงการใช้สารเคมีรุนแรง ตัวทำละลาย หรือน้ำยาทำความสะอาดที่มีฤทธิ์กัดกร่อน เนื่องจากสิ่งเหล่านี้อาจสร้างความเสียหายให้กับผิวเคลือบหรือส่วนประกอบภายในได้

6.2 การดูแลแบตเตอรี่

• ถอดแบตเตอรี่ออกจากเครื่องส่งสัญญาณหากไม่ได้ใช้งานเป็นเวลานาน เพื่อป้องกันการรั่วไหล
• If using rechargeable batteries, follow the manufacturer's guidelines for charging and storage to maximize battery life.

6.3 พื้นที่จัดเก็บ

Store the transmitter in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity. Use a protective case to prevent physical damage during transport or storage.

7 การแก้ไขปัญหา

If you encounter issues with your Shure ULXD2/B58 Handheld Transmitter, consider the following common troubleshooting steps:

• ไม่มีไฟฟ้า: Ensure batteries are correctly installed and fully charged. Check the power button for proper function.
• No Audio/Signal Loss:
  • Verify that the transmitter is powered on and within range of the receiver.
  • Confirm that the transmitter and receiver are tuned to the same frequency band and channel. Re-sync if necessary.
  • Check for potential sources of RF interference in the operating environment.
  • Ensure the receiver's output is correctly connected to your audio system.
• คุณภาพเสียงไม่ดี:
  • Check microphone placement and distance from the sound source.
  • Inspect the microphone capsule for any physical damage or debris.
  • Verify gain settings on both the transmitter and receiver to avoid clipping or low signal.
  • Ensure the correct microphone capsule is securely attached.
• การรบกวน: The ULX-D system is designed for robust RF performance. If interference occurs, perform a scan on your receiver to find clear frequencies and re-sync the transmitter. Avoid operating near other wireless devices or strong RF sources.
