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.
