Bose 802c System Controller

  
Good working condition but has scratches as shown in photos. The 802 C System Controller is a sophisticated signal processing device that combines the functions of three equalizers, an automatic switching circuit, and an electronic crossover. The 802C system controller automatically selects the proper crossover function and equalization curve for a given system application through use of a switching network operating in conjunction with the unit's output jacks. In addition to signal routing based on equalization requirements, the switching network indicates mode of operation on its front panel.

The front panel also includes high-cut and low-cut switches which decrease line output by 4dB at 55Hz and by 10dB at 16kHz. Sharp subsonic and ultrasonic band-limiting filters reduce power waste, stage noise, high-frequency instability, and interference. Without the 802c controller your 802's Mk2 / 302 speakers will not perform optimally as designed. The Bose 802c system controller was designed for 802 Mk2 / 302 loudspeakers speakers.
