Three channel conguration (Only SMQ):
In three channel conguration, two outputs are used in normal operation mode and both other outputs are
switched in bridged mode while feeding the amplier with a stereo input signal. This conguration is commonly
used when two mid/high frequency loudspeakers are supplemented with an additional (mono) bass cabinet for
the low frequencies. The mid/high frequency loudspeakers are connected as described in normal operation
mode, while the bass cabinet is connected as described in bridged mono mode.
Besides the selection for the bridged amplier channel, further advanced settings such as ltering is usually
congured for this kind of setups. All these settings can be congured by the user interface which is controllable
using the front panel controls.
