A fully bidirectional wireless system

Sennheiser Spectera is the world's first bidirectional wideband solution for digital broadcasting, enabling the simultaneous wireless transmission of musicians' microphone and in-ear signals. First presented at the IBC in 2024, this innovative wireless system's revolutionary WMAS technology significantly reduces the overall complexity of the unit. It's also remarkably resistant to RF fading, allowing the wideband HF channel to be used with a great degree of flexibility. Musicians will also love the fact that the Spectera can achieve a latency of only 0.7ms when transmitting in-ear signals; furthermore, reliable handling is guaranteed thanks to its time-saving workflows, frequency spectrum monitoring, and full remote control. This extraordinary range of features makes the Sennheiser Spectera a great choice for any number of professional applications.

Transmitter and receiver in one

The Sennheiser Spectera SEK UHF is a bodypack designed for use with the Spectera wireless system, enabling the simultaneous transmission of in-ear and mic/line signals; it's both transmitter and receiver, i.e. bidirectional. Users connect their microphone (or any other line signal) using the three-pin socket, while plugging their in-ears into the 3.5mm headphone output, which is linked to an integrated headphone amplifier with adjustable impedance and a continuous rotary volume control. The Sennheiser BA 70 rechargeable battery (sold separately) provides a runtime of seven hours when fully charged, depending on the mode being used. Once an SEK bodypack transmitter is connected to the Spectera's base station, it can be remotely controlled and monitored with Sennheiser's LinkDesk software.

Professional standards

The Sennheiser Spectera system is aimed at professional users looking for a high-performance wireless device for multi-channel transmission. It gives musicians, sound techs, and venue operators complete control over all aspects of the transmission and monitoring process, with uninterrupted interference management via an audio network, as well as boasting other great features like its extremely low latency and high immunity to RF fading. This all adds up to make the Sennheiser Spectera a uniquely reliable solution for cable-free performances. Secure transmission is guaranteed by AES-256 encryption, with the SEK UHF bodypack transmitting in the 470–608MHz and 630–698MHz frequency ranges. The Sennheiser Spectera SEK 1G4 is a variant that operates in the frequency ranges of 1350–1400MHz and 1435–1525MHz.

About Sennheiser

In June 1945, Prof. Fritz Sennheiser founded the Wennebostel Laboratory, which initially produced measuring equipment. Commissioned by Siemens in 1945, the young company developed the MD-1 microphone, which was launched in 1946. After the development of further microphones, the company was renamed Sennheiser Electronic in 1958. Two years later, Sennheiser introduced the MD 421 dynamic microphone, which is still in production today and still held in high esteem by many sound engineers. Further groundbreaking developments, such as the HD 414 headphones and the classic MD 441 microphone, hugely enhanced the company's international reputation, eventually making Sennheiser one of the leading manufacturers of microphone and headphone systems in the world.

Flexible charging and connectivity

The Sennheiser Spectera SEK UHF is a wireless bodypack, so of course it needs charging prior to use. Sennheiser has come up with a number of options here, all available separately: There's the Sennheiser L 70 USB charger, the Sennheiser LM 6070 charging module for use with the 19" Sennheiser L 6000 charging unit, and the charging contacts on the Sennheiser CHG 70N-C. For even greater functionality, the bodypacks have a variety of audio connection modes, enabling users to adapt their Spectera devices for different applications. For instance, there's an extra-low latency mode, which does, however, require more capacity on the HF channel being used. The various modes can be managed using Sennheiser's LinkDesk software. The bodypack itself has a display providing information on the device's name and battery levels.
