Overview

The L Series LT from Lectrosonics is a digital hybrid wireless bodypack transmitter with a 75 MHz tuning bandwidth, a multi-function toggle switch, and the ability to respond to remote commands from RM or smartphone apps. It can be used to capture audio in environments for applications such as broadcast TV, theater, houses of worship, live stage, and more.

The LT has several other features to help you obtain good clear audio, such as selectable RF power at 50 or 100 mW, a compatibility mode to ensure analog receivers will work well with the transmitter, and a Servo microphone input allowing you to use a microphone or line level inputs.

In addition, the durable LT transmitter is enclosed in machined-aluminum housing. It has a detachable antenna that can easily be removed for transportation. An LCD and membrane switch interface make the LT transmitter easy to setup and simple to use.

    • Block A1: 470.1 to 537.575
    • Block B1: 537.6 to 614.375
  • Frequency Selection Steps: Selectable, 100 kHz or 25 kHz
  • RF Power output: Selectable, 50 or 100 mW
  • Pilot Tone: 5 to 32 kHz; 5 kHz deviation (Digital Hybrid mode)
  • Frequency Stability: ± 0.002 %
  • Deviation: ± 50 kHz max. (Digital Hybrid mode)
  • Spurious Radiation: 60 dB below carrier
  • Equivalent Input Noise: -120 dBV (A-weighted)
  • Input Level:
    • Mic: Nominal 2 mV to 300 mV, before limiting. Greater than 1V maximum, with limiting.
    • Instrument: 1M Ω high level
  • Input Impedance: 2K Ω
  • 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, Digital Hybrid Wireless Mode Only:
    • Frequency Response: 90 to 20 kHz ± 1 dB
    • Low Frequency Roll-Off: -12 db/octave; 70 Hz
    • THD: 0.2% (typical)
  • Signal to Noise Ratio @ Receiver Output:
    SmartNR No Limiting With Limiting
    OFF 103.5 108
    NORMAL 107 111.5
    FULL 108.5 113
    Note: The dual envelope "soft" limiter provides exceptionally 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.
