The Lectrosonics L Series line of wireless microphones also comes packaged as a system: LR / LMb or LR / LT. Please select frequencies when ordering.


The Lectrosonics LR Receiver is the latest successor to the line of economical beltpack transmitters designed for applications including theater, house of worship, TV, ENG, video and film production.

The ultra-compact LR Receiver is part of the L Series or "Large Bandwidth" line of wireless microphones. The other two components of the series are the LMb and LT Beltpack Transmitters. All three units share a wide tuning range of three standard Lectrosonics blocks, or 67.5 to 76.7 MHz, depending on the specific frequency band, and employ Lectrosonics' patented Digital Hybrid Wireless technology for compandor-free audio along with compatibility modes for inter-operability with older analog systems.

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.

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.

Lectrosonics LR Receiver - 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
  • Smart Squelch™ 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

CONSUMER ALERT: This particular wireless microphone device operates in portions of the 617-652 MHz or 663-698 MHz frequencies. Beginning in 2017, these frequencies are being transitioned by the Federal Communications Commission (FCC) to the 600 MHz service to meet increasing demand for wireless broadband services. Users of this device must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC's wireless microphone website or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).
