产品介绍
| 升级为 ULX 专业版无线系统的超高频系统，适用于职业音乐人和专业音频安装人员。多种系统配置提供了无限制的选择，每种配置均可选择使用出色的舒尔话筒或是乐器电缆。 适用于职业音乐人和专业音频安装人员的 UHF 系统。 |
| 主要功能 |
| 可以从超过 1400 个预先编入的频率中进行选择，同时通过“自动选择频率”功能可以立刻获得清晰的频道。 |
| 技术规格 | |
| RF Carrier Frequency Range | 470.000 to 865.000 MHz (Available frequencies depend on the applicable regulations in the country where the system is used). Refer to the frequency supplement supplied with the system. |
| Effective Range | 100 m (300 ft.) under optimal conditions |
| NOTE: Actual working range depends on RF signal absorption, reflection, and interference | |
| Audio Frequency Response | 25 to 15,000 Hz, ±2 dB |
| NOTE: Overall system frequency response depends on the microphone element. | |
| Transmitter Audio 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 |
| Transmitter Gain Adjustment Range | ULX1: 25 dB |
| ULX2: 25 dB | |
| Receiver Audio Output Level (±38 kHz deviation, 1 kHz tone) | XLR connector (into 600 ohm load): +3.9 dBV (line), –17 dBV (mic) |
| 1/4 inch connector (into 3000 ohm load): –2 dBV | |
| Impedance | ULX1 (input): 1 Megohm ULXS4, ULXP4 (output): 50 ohms at line level; 2000 ohms at mic level |
| Modulation | ±38 kHz deviation compressor-expander system with pre- and de-emphasis. |
| RF Power Output | ULX1, ULX2: 30 mW maximum |
| Dynamic Range | >100 dB, A-weighted |
| RF Sensitivity | 1.26 μV for 12 dB SINAD (typical) |
| Image Rejection | 80 dB typical |
| Spurious Rejection | 75 dB typical |
| Ultimate Quieting (reference ±38 kHz deviation) | >105 dB, A-weighted |
| System Distortion (reference ±38 kHz deviation,1 kHz modulation) | 0.3% total harmonic distortion, typical |
| Power Requirements | ULX1, ULX2: 9V alkaline battery; 8.4 V Nicad optional |
| ULXS4, ULXP4: 14 - 18 Vdc (negative ground), 550 mA | |
| Battery Life | 8 to 9 hours (with 9V alkaline battery) |
| Operating Temperature Range | - 20° to 49° C (- 4° to 120° F) |
| NOTE: Battery characteristics may limit this range. | |
| Overall Dimensions | ULX1: 96.5 mm H x 67 mm W x 26.7 mm D (3.86 x 2.68 x 1.10 in.) |
