The SB168-ES is an affordable 3U-size stage box that utilizes EtherSound technology to propagate digital sound signals. Each unit provides 16 channels of sonically-superb remote analog input – each with its own head amp – and 8 channels of analog output. Multiple units may be daisy-chained in sequence for simultaneous use. Compared to a conventional analog console + analog multicore the SB168-ES is noise resistant, and lets you boost quality by keeping the length of microphone cables as short as possible.
