Description

Superb Quality Wireless Transmission & Reception The digital wireless microphone system transmits & receives high-quality 24- bit/48-kHz digital audio in a specific frequency bandwidth that meets the Wireless Communication Regulations of each country. The system delivers a wide dynamic range of more than 106 dB, a wide frequency response of 20 Hz to 20 kHz, and an excellent transient response. Stable and Secure Transmission & Reception Incorporating the newly developed digital modulator, the digital wireless microphone system allows highly stable wireless transmission that is extremely tolerant to unwanted interference. In addition, the system transmits & receives digitally modulated and encrypted data to minimize the risk of interception, providing highly secure transmission & reception. Simultaneous Multi-channel Operation. The digital wireless microphone system allows for large-scale multi-channel operations. Thanks to the newly developed digital modulator, the system realizes an inter modulation-free, equally spaced channel allocation. The digital wireless transmission technology used in this system enables a significant increase in the number of simultaneous operations in comparison with current analogue wireless systems. For example, up to 16 channels of simultaneous operation is possible in an 8-MHz operating band. Input connector SMC9-4S (Sony 4-pin) (x1) Power requirement DC 3.0 V (two LR6 AA-size batteries) Sampling frequency 48 kHz Quantization bit length 24 bit Channel step 125 kHz Reference input level (at 0-dB audio attenuator level) DWT-B01 transmitter: 1 kHz, -60 dBV, 0 dBV=1 Vrms (1 kHz, -58 dBu, 0 dBu=0.775 Vrms) Frequency response 20 Hz to 20 kHz ±1 dB Signal-to-noise ratio 70 dB (typical) (A-Weighted, at reference input level) Total system audio delay Less than 4 msec
