Trantec S2.4BX 2.4GHz Digital Wireless Beltpack & Lapel Microphone System
The Trantec S2.4BX is a single channel 2.4GHz ISM Digital Wireless Beltpack and Lapel Microphone System with up to 16 selectable channels and an LCD display receiver — delivering licence-free, hands-free wireless audio for presentations, fitness instruction, theatre and events without the need for a handheld microphone.
The Trantec S2.4BX is a straightforward and reliable single-channel wireless beltpack microphone system operating on the completely free 2.4GHz ISM frequency band — meaning no licence is required for use in the UK.
Designed for any application where hands-free wireless audio is required, the S2.4BX is well suited to presentations, conferences, fitness instruction, theatrical productions, schools, houses of worship and a wide range of event and installation applications. With up to 16 selectable channels available, the system can be tuned to avoid interference in busy wireless environments for clean, reliable operation.
LCD Display Receiver
The S2.4BX receiver features a bright LCD display for clear and straightforward channel programming and signal status monitoring. The compact receiver connects to PA systems, mixers and amplifiers via the included output connections, and is powered via the included DC power supply. A single antenna provides reliable wireless reception, with a receiving sensitivity of -80dBm ensuring consistent signal pickup from the beltpack transmitter. The digital GFSK modulation system delivers a dynamic range of 85dB, THD of less than 0.1% and SNR of greater than 95dB for clean, accurate audio reproduction throughout.
Compact Beltpack Transmitter
The S2.4BX beltpack transmitter delivers 10mW of RF carrier power using GFSK digital modulation for stable, clean wireless transmission. Powered by 2 x AA batteries, the beltpack provides approximately 5 hours of continuous use on a single set of batteries. Please note that the beltpack requires a 3.5mm threaded mini jack microphone connection — the standard Trantec LP2, SJ33 and SJ66 microphone capsules are not compatible with this beltpack without adaptation, so please ensure any lapel or headset microphone used has the correct 3.5mm threaded mini jack connector.
