Trantec S2.4BBX Dual 2.4GHz Digital Wireless System with 2 x Beltpack & Lapel Microphones
The Trantec S2.4BBX is a dual channel 2.4GHz ISM Digital Wireless Microphone System supplied with two beltpack transmitters and two lapel microphones.
Delivering licence-free, hands-free dual wireless audio from a single receiver with individual XLR outputs and mixed jack output, ideal for presentations, fitness instruction, theatre and events requiring two simultaneous wireless feeds.
The Trantec S2.4BBX is a complete dual beltpack wireless microphone system that provides two simultaneous hands-free wireless microphone feeds — both operating on the completely free 2.4GHz ISM frequency band with no licence required for use in the UK.
Whether deployed for dual-presenter conferences, fitness instruction with two instructors, theatrical productions, schools or any other application where two simultaneous lapel or headset microphone feeds are required, the S2.4BBX provides a clean, reliable and ready-to-use solution straight out of the box. The dual receiver tunes to two different frequencies simultaneously across up to 16 selectable channels per transmitter, with smart ID code identifying synchronisation technology making setup and channel matching straightforward and fast.
16-Channel Digital Audio Technology
The S2.4BBX is built on Trantec's S2.4 series platform, which adopts the 2.4GHz ISM digital audio frequency with GFSK modulation and automatic radio interference filtering for completely RF-noise-free operation. The 16-bit, 38.4kHz audio format delivers clean, natural and detailed sound reproduction with THD of less than 0.1% and SNR greater than 95dB.
Digital Audio Processing Technology is comprehensively applied throughout the signal chain, ensuring that the audio output from both beltpack channels is consistently clear and natural in any environment. The dual receiver features individual channel XLR outputs at microphone level (-38dBu) alongside a line level A/B mixed ¼" output for flexible connection to mixing desks, PA systems and installed audio equipment.
Two Beltpack Transmitters & Lapel Microphones
Both S2.4-BTX beltpack transmitters deliver 10mW of RF carrier power using GFSK digital modulation for stable, clean wireless transmission up to 30 metres. Each beltpack is powered by 2 x AA batteries for approximately 5 hours of continuous use and is supplied with an S2.4-LMO lapel microphone as standard. The optional S2.4-HMU headworn microphone is also available separately for applications where a headset microphone is preferred over a lapel.
It is important to note that the beltpacks use a 3.5mm threaded mini jack microphone connection — standard Trantec LP2, SJ33 and SJ66 microphone capsules are not compatible without adaptation. Two antennas and rack ears are supplied as standard for flexible freestanding or 19" rack-mounted receiver installation.
