Shure ULXD2 là micro trong hệ thống không dây ULX-D Digital. Với vỏ nhôm nhẹ và chắc chắn và ăng ten tích hợp, micro ULXD2 truyền tải âm thanh cực kỳ chất lượng, hiệu suất phổ cao, mã hóa AES 256-bit để truyền an toàn và nhiều tùy chọn sạc tương thích với các hệ thống âm thanh chuyên nghiệp.
ULX-D System Specifications
- RF Carrier Frequency Range: 470–932 MHz, varies by region (See Frequency Range and Output Power table)
- Working Range: 100 m ( 330 ft)
Note: Actual range depends on RF signal absorption, reflection and interference.Note: Actual range depends on RF signal absorption, reflection and interference.
- RF Tuning Step Size: 25 kHz, varies by region
- Image Rejection: >70 dB, typical
- RF Sensitivity: −98 dBm at 10-5 BER
- Latency: <2.9 ms
- Audio Dynamic Range (A-weighted, typical, System Gain @ +10):
XLR Analog Output
|
>120 dB |
Dante Digital Output
|
130 dB |
- Total Harmonic Distortion (−12 dBFS input, System Gain @ +10): <0.1%
- System Audio Polarity: Positive pressure on microphone diaphragm produces positive voltage on pin 2 (with respect to pin 3 of XLR output) and the tip of the 6.35 mm (1/4-inch) output.
- Operating Temperature Range: -18°C (0°F) to 50°C (122°F)
Note: Battery characteristics may limit this range.
- Storage Temperature Range: -29°C (-20°F) to 74°C (165°F)
Note: Battery characteristics may limit this range.
- Receiver Output Level (The following table describes the typical total system gain from the audio input to the receiver outputs):
