Sony DWT-B01-E1424 Digital Bodypack Transmitter (470 - 542 MHz)

Share

The Sony DWT-B01 digital bodypack transmitter is compact, lightweight and built with a sturdy die-cast magnesium body. The /1424 model operates within a 72 MHz range, from 470 to 542 MHz. Audio input is selectable from either mic or line level. The DWT-B01 provides a choice of 1, 10 or 50 mW RF output. The transmitter operates for approximately 5 hours using two AA size alkaline batteries at 10 mW output power. The DWT-B01 supports use of alkaline, lithium, or nickel-metal hydride batteries. Transmitter functions; including input attenuator, RF frequency selection, RF power output, Audio LCF frequency and a power sleep mode (in the transmitter) can be remotely controlled from the digital wireless receiver.
