Neutrik - NX1TX-T

Xirium system transmitter (with mini XLR power supply and antenna) - Touring version. Xirium is a digital wireless system designed to replace analogue audio cables in situations where it may be difficult or inappropriate to run a cable, but where a stable connection and audio quality must be maintained. The system is suitable for conferences, live events and music performance and offers a solution for venues where cables are difficult to hide and trip hazards must be avoided including churches, historic buildings, museums, hotels and colleges.

Operating in the license-exempt 5GHz frequency band, the system can send or receive up to eight channels of uncompressed, studio quality, 24 bit, 48 kHz audio with only 3.4 milliseconds latency per circuit. Neutrik's in-house designed DIWA (Digital Wireless Audio) transmit and receive protocol, together with patented FEC forward error correction, results in robust, noise-free operation, even in the presence of heavy local RF traffic. To maximise RF coverage, the diversity antenna system can be augmented with optional, directional antennas. The system is designed for line of sight operation.

TX and TX-T transmitters accept microphone, instrument and line-level sources via a combination 3-pin XLR and 3-pole, 6.35 mm connector. Gain settings are controlled from the TRX base station and are adjusted in 8 dB steps, or 1 dB steps if a laptop is connected running XIRIUM Configurator software. Audio level monitoring is provided by the three-color LED next to the 'Gain Up/Down' buttons.
