Sony DWT-B30/L

Properties:

The DWT-B30 is a digital wireless pocket transmitter of the DWX series with a frequency response from 20 Hz to 22 kHz, which is especially suitable for multi-channel operation with high density for large productions. The pocket transmitter belongs to the 3rd generation of the professional DWX series and has four different codec modes for a variety of applications. MODE1 is compatible with the 1st generation DWX series devices, MODE2 prioritizes short latency times while maintaining transmission stability and high audio quality, MODE3 provides additional signal processing and suppresses noise caused by unexpected pulse noise, and MODE4 prioritizes audio quality while maintaining transmission stability and low latency. It transmits high-quality 24-bit audio within certain frequency bandwidths (depending on the country). The monitoring and control functions of Cross Remote™ allow input attenuation, RF frequency selection, RF output power, cut-off frequency for audio low-pass filters and sleep mode to be remotely controlled via the Sony DWR-S03D plug-in receiver. This eliminates unplanned shooting breaks and walking distances. The DWT-B30 is powered either by two LR6/AA alkaline batteries or USB.
