The DX1.5 is a 2 input 6 output digital loudspeaker
management system for use in both live applications and fixed
installations. Based on a processing platform running at 96kHz
the DX1.5 offers unrivalled performance and flexibility.
management system for use in both live applications and fixed
installations. Based on a processing platform running at 96kHz
the DX1.5 offers unrivalled performance and flexibility.
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.
