Micro không dây SHURE BLX24R/B58

Micro không dây SHURE BLX24R/B58

Hệ Thống Không Dây Với Micro Vocal Beta58A
Micro vocal dynamic Beta 58A được thiết kế dành cho biểu diễn trực tiếp và thu âm trong phòng thu. Đáp ứng tần số được điều chỉnh giúp làm nổi bật giọng hát và búp hướng supercardioid tách biệt giọng hát khỏi các nguồn âm thanh khác. Hệ thống có thiết lập đơn giản và giao diện trực quan cho hiệu suất cao.

System

• Working Range: 91 m (300 ft) Line of Sight
• Audio Frequency Response: 50 to 15,000 Hz
• Total Harmonic Distortion Ref. ±33 kHz deviation with 1 kHz tone 0.5%, typical
• Dynamic Range: 100 dB, A-weighted, typical
• Operating Temperature: -18°C (0°F) to 57°C (135°F)
• Polarity: Positive pressure on microphone diaphragm (or positive voltage applied to tip of WA302 phone plug) produces positive voltage on pin 2 (with respect to pin 3 of low-impedance output) and the tip of the high impedance 1/4-inch output.
