ATG-100T 195MHz Transmitter Only — Single Unit for ATG-100T/EXMAX Wireless Tour Guide Systems (1 Transmitter)

This listing is for one ATG-100T transmitter (transmitter only) compatible with the EXMAX ATG-100T wireless audio system. It sends the microphone audio to all paired receivers within range in a one-way audio configuration — a single transmitter can serve hundreds of receivers as long as they are tuned to the same channel. Coverage and channels: Typical transmission distance is about 50-60 meters (164-197ft). The system operates across 195MHz-230MHz with 99 frequency channels; these 99 select IDs allow at least 40 groups to operate simultaneously without mutual interference. Power and audio quality: Both transmitter and receivers include built-in 900mAh lithium upgraded batteries that provide more than 18 hours of continuous use. The design achieves a high signal-to-noise ratio (≥90dB) for clear voice transmission. Physical and input details: The transmitter weighs 56g while each receiver weighs 46g — compact and lightweight for easy transport. The unit features a 3.5mm input jack that accepts AUX sources (such as MP3 players, smartphones, MP4, CD players, etc.) and a microphone input. Note: the microphone and earphone cables act as antennas — fully extend these wires to improve signal reception. Channel setup: Transmitter and its receivers must share the same Channel ID within each group (for example: Group A — transmitter A set to Channel ID 05, receivers A set to Channel ID 05). Different groups should be assigned different Channel IDs to avoid cross-talk. Applications: Ideal for tour guiding, field trips, museum or exhibit guides, sermon interpretation, church translation, courtroom or courtroom translation, conferences, simultaneous interpreting, teaching, silent conferences, hybrid/blended learning, classroom listening centers, audiovisual labs, travel and tourism audio guides, family or restaurant events, Hajj, beach weddings, and other situations where discreet, group-only listening is needed. Notes: This is a one-way transmission system — it only transmits the speaker’s microphone audio to receiver earphones within the stated range. In open areas expect roughly 50 meters (160ft) effective reception for group listening.
