Wireless bodypack Specs

Model: Lectrosonics LMB-B1

Lectrosonics LMB Specs Channel B1 Frequency Range 537.600 to 614.375 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 Packaging Info Package Weight 0.855 lb Box Dimensions (LxWxH) 13.35 x 5.55 x 3.45"
