JTS JSS-4B Description

The JTS JSS-4B is designed for high-performance wireless applications with maximum channel flexibility and ease of use. Its PLL synthesized control provides rock-solid frequency stability within the 470–960 MHz UHF range, while its extended audio response from 50Hz to 18kHz ensures natural, high-fidelity vocal reproduction. With up to 3000 user-selectable frequencies and 15 preset groups of 63 compatible channels, this mic is ideal for dense RF environments such as live concerts, worship spaces, and multi-mic setups. Adjustable RF power (Low/High) allows users to optimize performance based on venue size and interference conditions. The JSS-4B supports JTS’s modular capsule system, giving users the flexibility to choose their preferred microphone element, including the optional TC-22 true condenser capsule. A durable aluminum alloy chassis and panel lock function prevent accidental changes and enhance stage durability. One of its most practical features is the integrated slot-in charging design, allowing performers to recharge NiMH AA batteries directly within the unit — minimizing downtime and streamlining power management.
