Wire up the system
The wiring of the system must be done according to the following rules, to guarantee a proper functioning of
the system in all circumstances.
1. Speaker cable for amplified outputs:
Minimum 2 x 1.5 mm²
If distance > 15 m: 2 x 2.5 mm²
2. Music sources and zone outputs:
Must be connected with high-quality audio cable and high-quality
connectors
Three channel configuration (Only SMQ):
In three channel configuration, two outputs are used in normal operation mode and both other outputs are
switched in bridged mode while feeding the amplifier with a stereo input signal. This configuration 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 amplifier channel, further advanced settings such as filtering is usually
configured for this kind of setups. All these settings can be configured by the user interface which is controllable
using the front panel controls.
