Up to 64 Channels in a Single Rack Unit

Spectera’s space-saving 1 RU base station features flexible digital I/O with redundant Dante and optional redundant Madi, assuring seamless integration into your audio network. Spectera’s transceiving antennas manage IEM signals, mic/line signals, and data simultaneously and up to four antennas can be added for redundancy, extended zone coverage, or additional spectrum capacity. Spectera’s simultaneous 32 I/O enables advanced flexibility for wireless mic, instruments, and in-ear monitoring applications in a single system. Configurations are completely flexible and can include up to 32 mic/line channels and 16 stereo IEMs serving your talent on stage or 32 interruptible foldback (IFB) across your crew.

Advanced Bidirectional Bodypacks

With Spectera’s bidirectional bodypacks, you have far more control and far fewer blind spots. Each Spectera SEK bodypack manages both an in-ear monitor and a mic/line input signal simultaneously. And with LinkDesk software, you have a full remote control and monitoring of everything: IEM volume, audio level and settings, RF health, battery status, and more. So, you can spend more time in control and less time managing components and chasing surprises. For in-ear monitors, Spectera delivers unprecedented RF performance and stability — equivalent to digital wireless microphones. With Spectera, you get stunning IEM clarity and accuracy with ultra-low latency down to 0.7 milliseconds.

Revolutionary Reliability

At the heart of Spectera is Sennheiser’s remarkable wireless multichannel audio technology (WMAS) and its unique modulation and multiplexing capabilities, which make Spectera vastly more resistant to dropouts and RF fading than narrowband systems. Spectera also features built-in redundancy where it matters most: redundant power supplies, redundant Dante and optional redundant MADI audio I/O, and the ability to connect multiple antennas for redundancy, additional zone coverage, or additional spectrum capacity.
