▪
Balanced (XLR) connection from preamplifier/processor to first subwoofer inputs.
▪
The first subwoofer’s input sensitivity should be set to match the preamplifier/processor outputs.
▪
In order to time-align the subwoofers the latency of the second subwoofer needs to be accounted for. This is done by
adding 0.86 m to the left and right distance setting in the first subwoofer. The distance used in the setting should be the
distance from the listening position to the second subwoofer plus 0.86 m. The subwoofer distance should be set as the
distance to the first subwoofer. See
▪
Balanced connection from first subwoofer outputs to second subwoofer inputs.
▪
The second subwoofer’s input sensitivity should be set to 0 dB.
▪
Balanced connection from second subwoofer’s outputs to the active main speaker’s inputs.
▪
The second subwoofer should be distance-aligned as described
.
▪
The subwoofers should be level-aligned using their volume setting.
