    This unique digital plug-on transmitter design will ideally match any microphone or line level source via a standard XLR connector. The Lectrosonics DPR can tune in coarse or fine steps across the UHF television band from 470.100 to 607.950 MHz, with a selectable output power of 25 or 50mW. The purely digital architecture utilizes AES 256-CTR encryption for high level security applications.

    The transmitter is specially designed with high efficiency digital circuitry for extended operating time on two AA batteries, with status indicated by a multi-color LED. An IR (infrared) port is included to simplify setup with IR enabled receivers. Updates can be made via microSD card.

    The input amplifier uses an ultra-low noise op-amp for quiet operation. It is gain controlled with a wide range, dual envelope limiter, providing over 30 dB of headroom above full modulation. A 24-bit A-D converter digitizes the audio, then filters out supersonic noise above 21 kHz.

    The antenna is formed between the machined aluminum housing of the transmitter and the attached microphone or cable. It functions as a dipole radiator when attached to a hand-held microphone and somewhat like a ground plane antenna when connected with a cable or plugged directly into a mixer. The conical shaped collar on the
    input coupler is made of DuPont Delrin to improve the ERP of the antenna in the uppermost frequency bands.

    Setup and adjustments are achieved through a backlit LCD, membrane switches and an intuitive menu structure. The DPR also offer hands free setup and adjustment using audible tones via the LectroRM mobile app. Remotely, the DPR can be powered on and off, and the frequencies and audio levels can be adjusted. Other features include input gain adjustment in 1 dB increments over a 55 dB range and adjustable low frequency audio roll-off for 3 dB down points at 25, 35, 50, 70, 100, 120 or 150 Hz to control subsonic and very low frequency audio content. Dual color LEDs indicate audio input level and the power LED changes color under low battery conditions.

    Alternate Recording Function
    The DPR transmitter may also be used as a stand-alone recorder. The industry standard .wav (BWF) file format employed is compatible with essentially any audio or video editing software. The DPR can be jammed with timecode sync for each audio file alignment during post production. The Storage media for the recorder is microSDHC memory card (HC Type)

    NOTE: The transmitting and recording functions cannot be used simultaneously. Users must choose to transmit or record.
