Lectrosonics Introduces L Series Wireless Microphone Products

Lectrosonics, the leading manufacturer of wireless microphone systems and audio processing products, has announced three new products in the company's L Series "Large Bandwidth" line of wireless microphones. The new L Series units all share a wide tuning range of three standard Lectrosonics blocks, or 67.5 - 76.8MHz, depending on the specific frequency band, and employ Lectrosonics' patented Digital Hybrid Wireless technology for compandor-free audio along with compatibility modes for interoperability with older analog systems. The new L Series product group consists of the LMb and LT beltpack transmitters and the LR miniature receiver.

The LMb is the latest successor in Lectrosonics' line of economical beltpack transmitters designed for applications including theatre, house of worship, TV, video, and film production. The LMb features an all-metal housing, wire belt clip, 50mW of RF power, 25 or 100kHz tuning steps (yielding up to 3,072 selectable frequencies), and an integrated multi-function switch with menu-selectable modes for power, mute, or talkback. A graphic LCD and membrane switch panel plus IR synch port make setup and operation a snap. Power is provided via two AA batteries.

Like the LMb, the LT transmitter features 25 or 100kHz tuning steps (yielding up to 3,072 selectable frequencies), an integrated multi-function switch with menu-selectable modes for power, mute, or talkback, and a graphic LCD and membrane switch panel plus IR synch port for ease of setup and operation. The LT additionally facilitates user-selectable RF transmission power of 50 or 100mW. A detachable antenna adds to the LT's versatility by allowing for remote mount antennas. Also, the LT responds to remote commands from either the dedicated Lectrosonics RM remote unit or smartphone apps with this capability. Along with the standard Lectrosonics microphone input, a user-selectable 1MOhm input is ideal for use with musical instruments, including guitars with passive pickups. The LT is housed in a newly designed machined aluminum housing featuring a hard EbNi 'Ebony' conductive finish. Power is provided via two AA batteries. Applications for the LT transmitter include TV and film production, stage, musical instruments, camera hops, corporate AV, and many others.

The ultra-compact LR receiver is designed to be ultra-portable for use with DSLR, 4/3, small 4K, and other compact HD cameras, the LR's diminutive size belies the technology inside. The wide tuning bandwidth with tracking front-end filters provides plenty of flexibility while avoiding the vulnerabilities of wider pass bands. Tuning steps are user selectable at 25 or 100kHz, yielding up to 3,072 operating frequencies. Compatibility modes enable the LR to operate with older analog transmitters. Dual antenna diversity improves range and resistance to dropouts. The RF spectrum analyzer and Lectrosonics' SmartTune capability make quick work of finding clean frequencies on site. A large, backlit LCD provides instant, clear information for setup and status monitoring while operational. Detachable antennas allow for remote antenna mounting. The unit is powered with two AA batteries.

All three L Series units are available in four different frequency ranges for worldwide use: A1 (470.100 - 537.575MHz), B1 (537.600 - 614.375MHz), C1 (614.400 - 691.175MHz) and D1 (691.200 - 767.975MHz). Overall system audio specifications are as follows: digital conversion: 24 bit/88.2kHz sampling rate. Frequency response: 40 - 20kHz +/- 1 dB, THD+N = 0.3 % in Digital Hybrid mode, > 95dB s/n ratio. Audio output levels are adjustable from - 50 to +5dBu in 1dB steps.

Karl Winkler, Lectrosonics' director of business development, commented on the company's new L Series products. "These new wireless mic products fill a growing need for frequency flexibility in the face of ever more crowded and shrinking RF spectrum. We've taken our hard-won experience in making robust, reliable, and user-friendly wireless microphones along with plenty of user input and distilled this knowledge into these three products. The super-small LR in particular should be of interest to the growing population of digital filmmakers using smaller and smaller cameras."
