The SB210A is an active bass unit, which has two extra channels for powering a pair of satellite speakers. Answering the demand for Funktion-One sonic quality in home, studio and small entertainment spaces, the SB210A - together with a pair of Funktion-One F55s, F81s or F101s - delivers a complete and easy to set up system.


The SB210A package enables users to experience Funktion-One sound in smaller environments without having to invest in all of the separate elements - speakers, a bass unit, an amplifier or crossover unit. Now those who have experienced the sonic qualities of large format Funktion-One systems can equip their studio, use the system as a home hi-fi, or for small events - such as a gallery exhibition or a small party for up to around 100 people. The extremely low fan noise, which is a fundamental part of the amplifier’s design, minimises any environmental disturbance for noise-sensitive applications, like studios.   


Taking a stereo line input from an XLR or quarter-inch-jack connection, the SB210A offers three set crossover points at 100Hz, 125Hz or 150Hz. It features separate level control for bass and for the satellite speakers, and a polarity reverse switch for the bass output. The unit has been designed for the specific requirements of Funktion-One’s drivers and has been optimised accordingly. It comes with limiting and protection configured for both the bass unit and the satellite speakers.
