To address an increasing demand for more wireless channels in location production, the Octopack combines up to four SRa Series compact receivers into a lightweight, rugged assembly with self-contained power supply and antenna signal distribution. This powerful production tool provides up to eight audio channels in a tiny package ready to work in applications from production cart to a portable mixing bag.
High quality antenna distribution requires the use of ultra quiet RF amps plus isolated and optimally matched signal paths through the circuitry to ensure equal performance from all connected receivers. In addition, the amplifiers used must be high overload types to avoid generating IM (intermodulation) within the multicoupler itself. Octopack meets these requirements for RF performance.
Lectrosonics Quadpack
Lectrosonics heeft naast de 8 kanaals Octopack ook een 4 kanaals uitvoering uitgebracht, de Quadpack. Twee SR/SRA type ontvangers (welke beiden al twee complete ontvangers in zich hebben) kunnen in de unit worden geschoven, zodat een compacte 4 kanaals ontvanger-unit ontstaat met vier gebalanceerde XLR uitgangen en een Hirose voedings connector.
De Quadpack is afgestemd op de maten van de industrie-standaard Sound Devices mixers en vormt daarmee een compact en robuust geheel.

The TM400 system was designed to provide the ideal link between calibrated test microphones and measurement equipment such as SIM®, SIA SMAART Live®, TEF® or other systems. By using a radio link, long cables can be eliminated thus saving time and providing opportunities for additional measurements to increase accuracy. The microphone can even be moved around in the venue while the audience is present – something that is impossible with a cabled measurement microphone.
Lectrosonics Digital Hybrid Wireless™ (U.S. Patent Pending) uses a proprietary algorithm to encode the digital audio information into an analog format which can be transmitted in a robust manner over an analog FM wireless link. This combination offers the superb audio quality of a pure digital system and the outstanding operating range of the finest FM wireless systems. The digital audio chain eliminates compandor artifacts, and provides audio frequency response flat to 20 kHz. The RF link takes advantage of the spectral efficiency characteristics of an aggressively optimized FM radio system.
This digital/analog hybrid technique has some very beneficial properties. Because the information being transmitted is digitally encoded, useable dynamic range is much higher than a compandor can offer and there is no compandor in the audio signal to interfere with your measurements.
The TM400 system comes standard with the HM transmitter, R400A receiver, and CCTM400 water-resistant case. However, the components can be ordered separately. Also, the R400A receiver can be ordered with a rack-mount front panel, at an additional cost.
