Note: The TM400 is not CE certified for use in the European Union. If you plan to travel internationally with your wireless system, the Lectrosonics ZS-LRHMa kit is CE compliant..


The TM400 system is an all-in-one turnkey wireless measurement kit. Just add a microphone, an interface, and a computer running Smaart.

Like the ZS-LRHMa kit, the TM400 is based around Lectrosonics Digital Hybrid Wireless technology, using a proprietary algorithm to encode the digital audio into an analog format to be transmitted over an analog FM wireless link. This combination offers the superb audio quality of a pure digital system and the outstanding operating range of one of the finest FM wireless systems. The digital audio chain eliminates compander artifacts, and provides an audio frequency response that is flat from 30Hz -20 kHz.

All Lectrosonics systems are manufactured in the USA to exacting standards. The TM400 is ruggedly build and engineered to deliver years of reliable service, even in the most demanding environments. This complete kit includes an HMa transmitter, R400a receiver, XLR pin swap adapter (required for use with Earthworks microphones), and a foam fitted water resistant hard case.

Note: Rational Acoustics only stocks B1 band systems. Other blocks are available as special order via email. Check out the Lectrosonics Wireless Measurement Buyers Guide for more information on frequency band selection.
