Stereo signal management
With dual XLR combo connections, the VARI 2318S accepts both balanced and unbalanced XLR inputs, as well as 1/4" jacks. Stereo XLR throughputs let you connect the subwoofer with a set of VARI Series or other powered speakers. Selectable crossover frequency and a phase switch put you in control of output and matching the sub perfectly with external speakers. An output level control lets you dial in the perfect amount of bass without affecting output to the connected mains.
