The Riedel NSA-003A is a versatile 2-wire analog intercom adapter that combines a compact design with advanced functionality. With two physical 2-wire connections, this interface allows connections between up to four third-party analog partylines and digital/IP-based intercom systems like Artist and Bolero. The inclusion of a stereo USB-audio interface facilitates easy streaming of audio from a connected device directly into the AoIP network, while three GPIOs enhance the device with call and mic mute capabilities via external buttons. Together with auto echo cancellation support, this feature set makes the NSA-003A an essential tool for production environments where reliability, flexibility, and interoperability are paramount.
The Riedel NSA-003A is designed with IP-centric workflows in mind, supporting open standards such as AES67, SMPTE 2110-30 and 31, and NMOS IS-04, IS-05, IS-07, and IS-08. It features dual PoE and SMPTE 2022-7 redundancy with in-band or out-of-band management, ensuring reliable performance even in the most demanding conditions. Built for silent fan-less operation in environments up to 30 °C, the NSAs also have a temperature-controlled fan for use in temperatures as high as 55 °C. With their compact 1 RU 1/3-rack size, they offer versatile mounting options, including desktop, wall, rack, and VESA mounting configurations.
