Lectrosonics DPR-A Xmitter Digital Plug-On

The DPR-A is a plug-on transmitter, it features a unique design compatible with any microphone or line level source via a standard XLR connector. The DPR-A operates within the UHF television band from 470.100 to 607.950 MHz, with tuning options of 100 kHz or 25 kHz steps, and offers selectable output power of 25 or 50 mW. Its digital architecture ensures security with AES 256-CTR encryption. Equipped with an external antenna, it delivers exceptional operating range.

Designed for efficiency, the transmitter incorporates high-efficiency digital circuitry for prolonged battery life on two AA batteries, indicated by a multi-color LED status display. Simplified setup is facilitated through an included IR port for IR-enabled receivers, while updates can be performed via SD card.

Featuring an ultra-low noise op-amp, the input amplifier ensures quiet operation, while its wide-range, dual-envelope limiter provides over 30 dB of headroom above full modulation. Audio is digitized through a 24-bit A-D converter, with supersonic noise filtered out above 21 kHz.
