6. The DSP bass management system splits the signal from each input into low and high frequency components Signal content below the cross over frequency is reproduced by the subwoofer and signal con tent above the crossover frequency is reproduced by the loud speakers connected to the outputs of the subwoofer Frequencies above the cross over frequency from input 1 are directed to out put 1 frequencies above the cross over frequency from input 2 are directed to output 2 and so on In a practical example a cable carrying Left and Right signals is connected first to INPUT num ber 1 on the subwoofer and then the OUTPUT number 1 is con nected to Left and Right loudspeakers For bass management to work the subwoofer must be first in the audio chain but after that the loudspeakers can be connected in any order Depending on the digital source transmission of a 192 kHz sam ple rate signal is achieved using single wire mode at quad rate or dual wire mode at double rate In the later case one audio channel uses one AES EBU cable Each of the DSP subwoofer inputs switch automatically to dual wire mode when a dual wire signal is connected to the input If the digital source can control the digital level it may still be advantageous to lower the sensitivity either with the GLM or the SYSTEM LEVEL control of the DSP subwoofer This will enable the use of the upper end of the digital level controller All digital audio inputs and outputs are
