SoundTube WLL-TR-1P-II Wireless Transmitter/Receiver System

The SoundTube WLL-TR-1P-II Wireless Transmitter/Receiver System puts dependable, high-fidelity assistive listening where you need it most — from auditoriums and houses of worship to secure monitoring rooms and surveillance points. This pro assistive listening device transmits uncompressed 2-channel audio with a full 20 Hz–20 kHz frequency response and under 20 ms latency, preserving speech clarity for listeners and security personnel. With three RF channels and an alternating-channel design to preempt interference, the WLL-TR-1P-II maintains consistent audio for public-address, monitoring, and ADA applications. Integrators will appreciate flexible inputs (USB, stereo mini, 1/4" balanced) and versatile outputs — and the system supports up to six receivers per transmitter for multi-zone coverage. A High/Low power selector controls RF range to avoid bleed into adjacent areas, making it suitable for IT, physical security, and surveillance deployments. Rugged metal construction and CE/FCC/RoHS/UL certifications ensure long-term reliability on professional installs.
