STACKED SUB CORRECTION
The Stacked subs option is designed for stacked multiple-subwoofers configurations.
When multiple subwoofers are used to reproduce a same signal, the perceived level increases. The Altitude 32
automatically decreases the signal sent to each subwoofer to maintain the same perceived level depending on the
number of subwoofers used to reproduce a same signal and the way subwoofers are located across the room.
In such multiple subwoofers configurations, two typical cases are handled by the Altitude 32 :
 If subwoofers are considered as decorrelated (away from each other), their power add up.

If subwoofers are considered as correlated (positioned next to each other or stacked), their amplitude add up.
Therefore, whether the stacked subs option is disabled (default) or enabled, an automatic attenuation of the signals will
be calculated accordingly to maintain a consistent perceived level.
