6.5 Crossover network

The mixer is equipped with a crossover network that is used to send
a low-bass signal for operating subwoofer speakers� For this purpose,
a low-pass filter can be activated for Bus 8� Regardless of this, the
signal of the sum channel L / R MIX OUTPUT can be cut off in the
low-frequency range so that the signal will be split to the two ways�
Requirements:
– All input channels whose input signals are also to be sent to the
subwoofer must not only be assigned to the sum channel but also
☞
to Bus 8 ( chapter 5�2�2)�
– Bus 8 must be assigned to the outputs which are connected to the
amplifier inputs of the subwoofers (
– If only a mono subwoofer is to be used, the mono sum of the signal
can be created via the function "Sum" of Bus 8 (
