The Sony DWTP01/E4250 Digital Plug-on Transmitter
adapts to XLR terminated microphones and enables them to be used with
Sony UHF wireless microphone receivers operating on UHF channels 42/51:
638 to 698MHz. The transmitter features 48V phantom power for condenser
microphones and digital audio processing for lower noise and longer,
efficient range.
Up to three selectable output power settings
are provided for maximum results and improved battery efficiency. Two AA
alkaline batteries power the DWT-P01 for up to 5 hours at the 10mW
power setting. Additional features include an input attenuator, RF
frequency selection, RF power output, Audio LCF frequency and a power
sleep mode (in the transmitter) that can be remotely controlled from the
DWR-S01D digital wireless receiver.
