- Hands-On Review : Lectrosonics L-Series Wireless System
The LT from Lectrosonics is a digital hybrid wireless beltpack transmitter with 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. This transmitter operates in the A1 frequency range between 470.100 to 537.575 MHz.

Lectrosonics LT-A1 specs
| Channel | A1 |
| Frequency Range | 470.100 to 537.575 MHz |
| Frequency Selection | Steps: Selectable 25 or 100 kHz |
| RF Power Output | 50 or 100 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 |
Mic: Nominal 2 to 300 mV, before limiting Greater than 1 V maximum, with limiting Instrument: 1 MOhm high level |
| 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 |
