1.INTRODUCTION

The  DSP

306/408 

USB is  a  complete  digital  loudspeaker  management  system 

designed  for  the  touring  or  fixed  sound  installation  markets.  The  absolute  latest  in 
available  technology  is  utilized  with  40-bit  floating  point  processors  and  high 
performance  24-bit  Analogue  Converters.  The  high-bit  DSP  prevents  noise  and 
distortion  induced  by  truncation  errors  of  the  commonly  used  24-bit  fixed-point 
devices. A complete set of parameters include I/O levels, delay, polarity, 8 bands of 
parametric  EQ  per  channel,  31  bands  of  graphic  EQ  per  input,  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 configurations to meet any 
requirements. 

The DSP

306/408 

USB can be controlled or configured in real time on the front panel 

or with the intuitive PC GUI accessed via the USB interface (or optionally Ethernet). 
Software  upgrade  for  CPU  and  DSP  via  PC  keeps  the  device  current  with  newly 
developed algorithms and functions once available. 

Multiple setup storage and system security complete this professional package.
