Sennheiser Spectera Base Station

At the center of every Spectera system, the Sennheiser Spectera Base Station is a 1RU unit that gives up to 64 channels, 32 in and 32 out, over up to two independent wideband RF carriers.

Each carrier is 6 or 8 MHz wide in UHF or 1G4, as the regional license allows. The unit must be activated with a license for its region before it runs, and the license is sold separately.

Antennas and Audio

Four ruggedized RJ45 antenna ports power up to four DAD antennas over PoE, each on Cat 5e or better cable up to 100 m. Extra antennas add redundancy, coverage, or spectrum. Audio leaves on redundant Dante, and two optional slots take redundant MADI cards in optical or BNC versions.

Sync, Control, and Power

The Base Station runs at 48 or 96 kHz, with a sample rate converter on every audio interface and wordclock in and out on BNC. A secured RJ45 network port gives full remote control in the Spectera WebUI or SoundBase. Two internal power supplies, 100 to 240 V AC, back each other up.

On the Front Panel

You set up the unit with an OLED display and jog wheel, and a headphone output with its own volume control lets you listen to any channel.

License Information

The Base Station must be activated with a free-of-charge License for the zone of the certified country. The license activation of the Base Station takes place through the LinkDesk software. A Spectera system is operational only after the Base Station has been activated with a license. This ensures reliable performance in compliance with regulatory standards. Each Base Station requires its own individual, device-specific license to become operational.

The License technically defines parameters such as frequency range (start and end range), transmission power, and transmission bandwidth (6 MHz or 8 MHz, depending on local regulations). Regulatory certifications determine which of these parameters can be used in any given country.

Please note, you cannot use multiple licenses for international usage or run multiple licenses on a single Base Station. Spectera employs a single node-based license tied to a specific device, which restricts feature activation and use to that device alone. Re-licensing is not offered.

The appropriate system license should be ordered with each Base Station purchase. A license code will be sent via email after the purchase.

It is the responsibility of the user to inform themselves about the current local regulatory and certification requirements and to comply with them when using wireless systems.
