Insertion or Cascade connection
If you use the insertion or cascade mode, you must set the 'Ins/Casc' switch, on the rear, in the correct position. The
insertion mode can be used to connect an external sound-processing device, e.g. an equaliser. To increase the number
of input channels, you must use the cascade mode to link pre-amplifiers. E.g. with 2 pre-amplifiers, the second pre-
amplifier has 8 channels on its master output (4 channels from the first pre-amplifier and 4 channels of its own).
