Description
Excellent performance in a small package for ENG and DSLR video production is the purpose and intent of the LR receiver design. Tracking front-end filters block interference from high powered RF signals on nearby channels to preserve the extended operating range. RF spectrum scanning displays accurate results on the LCD to make finding clear spectrum quick and easy.
Features:
- Tunes over a 75 MHz range*
- Tracking front-end filters
- Digital Hybrid Wireless¨ with compatibility modes for use with earlier transmitters
- Compact size powered by two AA batteries or an optional battery eliminator
- LCD with RF spectrum scanning
- SmartSquelchTM noiseless muting adapts automatically for near/far operation
- DSP-based pilot tone for squelch control
- USB port for firmware updates
- IR sync port for transmitter setup
The receiver is powered by internal AA batteries or with an optional battery eliminator. The top panel includes an IR port for transmitter setup. Firmware updates are enabled via a USB port on the side panel. The housing is made from a solid machined aluminum billet.
Included Accessories:
- 2 - AA Batteries
- 2 - AMJXX (Specify Block)
- 1 - 26895 Wire Belt Clip (Installed on Transmitter)
| Operating Frequencies | Band A1: 470.100 - 537.575 MHz Band B1: 537.600 - 614.375 MHz* Band C1: 614.400 - 691.175 MHz *North American transmitter models exclude the radio astronomy frequency allocation from 608 to 614 MHz. | ||||||||||||

| Note: The dual envelope "soft" limiter provides exceptionally good handling of transients using variable attack and release time constants. Once activated, the limiter compresses 30+ dB of transmitter input range into 4.5 dB of receiver output range, thus reducing the measured figure for SNR without limiting by 4.5 dB. | |||||||||||||
