The DX1.5 has standard routing matrix configurations, such as  
2 x 3-way, as well as flexible routing allowing any output to be  
fed from any input or sum of inputs. Each output consists of a  
high and low filter, 9 bands of parametric equalisation, limiter,  
delay (adjustable in 0.3µs steps), gain and polarity.
