The JTS SIEM-2 In Ear Monitoring System is a complete, affordable mono in-ear monitoring system designed for reliable stage performance and professional audio monitoring. This kit includes the SIEM-2T transmitter, SIEM-2R bodypack receiver, and the IE-1 in-ear earphones, providing everything needed for clean, consistent monitoring in rehearsals, live shows, houses of worship, and touring setups. Operating on either licence-free Channel 70 (863–865MHz) or CH38–CH40 (region dependent), the SIEM-2 offers a straightforward and dependable alternative to traditional wedge monitoring, helping to reduce stage volume while improving clarity and giving performers more control.
Built for practical stage use, the SIEM-2 system combines a robust transmitter with balanced dual XLR inputs and loop-through connectivity, allowing easy integration into mixing desks and monitor sends. The compact SIEM-2R bodypack receiver is designed for comfortable belt-worn operation and includes simple on/off, channel selection, and volume control for quick adjustment during a performance. The included IE-1 in-ear earphones feature a lightweight, dynamic design with a clear full-range response, making them suitable for vocals, instruments, and general stage monitoring. With reliable PLL synthesised control and clear LED channel displays, the SIEM-2 is engineered for straightforward setup and consistent performance.
