Lectrosonics DPR-A Digital Plug-On Wireless Transmitter/Recorder with Whip Antenna (470 to 608 MHz)

Wideband UHF tuning range – 470-608 MHz
Accepts microphone or line level signals
Selectable 5, 15, 48 volt phantom power
Selectable 25/50 mW RF output power
Adjustable low frequency roll-off
Powered by two AA batteries
IR (infrared) port for fast setup
Remote controlled “dweedle” tones (audio tone set-up control)
Removeable SMA-mount antenna
Solid machined aluminum housing
On board recording with time code jam sync
Encryption 256 Bit AES, CTR Mode

This unique plug-on transmitter design will ideally match any microphone or line level source via a standard XLR connector. The DPR-A can tune in 100 kHz or 25 kHz steps across the UHF television band from 470.100 to 607.950 MHz, with a selectable output power of 25 or 50 mW. The purely digital architecture utilizes AES 256-CTR encryption for high level security applications. The external antenna provides exceptional operating range.

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 SD 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.

Included

PHTRAN3-A pouch with belt clip
AA Lithium batteries
AMM-19 antenna
AMM-22 antenna
