Lectrosonics LMB, TX, BASIC BELT PACK, FIXED ANT, 50 mW, 75 MHZ BANDWIDTH, 2 AA

The Lectrosonics LMB can be configured to operate as a "one touch" device with a single power on/off switch on the top panel, or with full access to all operational parameters using the side panel membrane switches and LCD interface. The top panel switch of the Lectrosonics LMB can also be configured to provide a mute or talkback function. This versatility makes the transmitter at home in a wide variety of applications from video production to theater, stage and house of worship. Along with providing peerless audio quality with wide frequency response and dynamic range in Nu Hybrid mode, the technology used in the LMb includes compatibility modes for Lectrosonics Mode 3 and IFB receivers. Frequencies are selectable in 100 kHz or 25 kHz steps across a maximum tuning range of 76.7 MHz. This yields a total of 3072 available frequencies across three standard frequency blocks. The tuning range varies in other blocks to meet applicable frequency allocations.

The Lectrosonics LMB has 2 frequency range:

LMB A1: 470.100 to 537.575 MHz
LMB B1: 537 to 614 MHz

Lectrosonics LMB Main Features

Covers four standard frequency blocks (depending on area of operation)
Digital Hybrid Wireless for compandor-free audio
50 mW RF or 100 mW EIRP power (depending on area of operation)
Compatibility modes for use with analog receivers
25 or 100 kHz tuning steps
Integrated multi-function switch for mute or talkback modes
Wide range input gain control in 1 dB steps

Specifications

Channel	A1, B1
Frequency Range	A1 : 470.100 to 537.575 MHz / B1 : 537 to 614 MHz
Frequency Selection	Steps: Selectable 25 or 100 kHz
RF Power Output	50 mW
Pilot Tone	25 to 32 kHz, 5 kHz deviation (Digital Hybrid mode)
Frequency Stability	± 0.002%
Deviation	± 75 kHz max. (Digital Hybrid mode)
Spurious Radiation	60 dB below carrier
Equivalent Input Noise	-120 dBV (A-weighted)
Input Level	Nominal 2 mV to 300 mV, before limiting Greater than 1 V maximum, with limiting
Input Impedance	2 kOhms
Input Limiter	DSP controlled, dual envelope "soft" limiter with greater than 30 dB range
Gain Control Range	44 dB, digital control
Modulation Indicators	Dual bicolor LEDs indicate modulation of -20, -10, 0 and +10 dB referenced to full modulation LCD bar graph

Audio Performance

Frequency Response	90 Hz to 20 kHz (+/-1 dB)
Low Frequency Roll-Off	-12 dB/octave, 70 Hz
THD	0.2% (typical)
SNR at Receiver Output	SmartNR: Off 103.5 (no limiting) 108.0 (with limiting) Normal: 107.0 (no limiting) 111.5 (with limiting) Full: 108.5 (no limiting) 113.0 (with limiting) Note: The dual envelope "soft" limiter provides 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
Switch Controls	Top panel slide switch; programmable as power, mute, talkback or no (off) function Side panel membrane switches with LCD interface for power on/off and all setup and configuration controls
Audio Input Jack	1x Switchcraft 5-pin locking (TA5F)
Antenna	Galvanized steel, flexible wire
Battery	2x AA alkaline, lithium, NiMh rechargeable
Battery Life	Alkaline: 4.5 hours Duracell Quantum: 7 hours Eneloop 2400 mAH NiMH: 8 hours
Dimensions (L x W x H)	3.2 x 2.4 x .8" (81 x 61 x 20 mm)
Weight	5 oz (141 g), including lithium AA batteries and wire belt clip
