The L Series units all share a wide tuning range of three standard Lectrosonics blocks, or 67.5 to 76.8 MHz, 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 theater, house of worship, TV, ENG, video and film production. The LMb features an all-metal housing, wire belt clip, 50 mW of RF power, 25 or 100 kHz 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 100 kHz 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 100 mW. 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 1 MOhm 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 super-hard EbNi ‘Ebony’ conductive finish. Power is provided via two AA batteries. Applications for the LT transmitter include TV and film production, ENG, stage, musical instruments, camera hops, corporate AV, and many others.
The ultra-compact LR receiver takes the Lectrosonics Digital Hybrid Wireless compact receiver concept to an entirely new level. 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 100 kHz, 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 LT is housed in the latest machined aluminum shell with super-hard EbNi ‘Ebony’ conductive finish. 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 – 537.575 MHz), B1 (537.600 – 614.375 MHz), C1 (614.400 – 691.175 MHz) and D1 (691.200 – 767.975 MHz). Overall system audio specifications are as follows: digital conversion: 24 bit/88.2 kHz sampling rate. Frequency response: 40 to 20 kHz +/- 1 dB, THD+N = 0.3 % in Digital Hybrid mode, > 95 dB s/n ratio. Audio output levels are adjustable from – 50 to +5 dBu 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.ʺ
