TR 4080D DIGITAL CONTROLER  
     
The TR 4080D is a 4 input - 8 output digital loudspeaker management system. It has 32-bit (40-bit extended) floating point processors and high performance 24-bit Analog Converters and its high-bit DSP prevents noise and distortion. A complete set of parameters include I/O levels, delay, polarity, 6 bands of parametric EQ per channel, multiple crossover selections and full function limiters. Precise frequency control is achieved with its 1 Hz resolution. Inputs and outputs can be routed in multiple configuration to meet any requirements.
