Lectrosonics - DPR-A/E01-A1B1

This unique plug-on transmitter is developed to match a microphone signal or line signal coming on XLR. The frequency of the DPR-A can be set in 100kHz, or 25kHz steps between 470.100 to 614.375mHz and with a selectable transmit power of 25mW or 50mW.†

The all-digital architecture uses an AES256-CTR encryption for applications where safety is important.

The transmitter is specially designed to be efficient in order to get as long a battery life as possible on two AA batteries. A multi-colored LED shows how much battery is left. An IR port allows it to be configured via a receiver with IR. Firmware updates are done with SD card.

The input amplifier has a low-noise op-amp to make the transmitter really quiet. The AD conversion is in 24 bits and has an antialiasing filter that filters out all information above 21kHz.
