7 SYSTEM CHECK ALIGNMENT GUIDELINES
The NEXO TD Controllers factory delay presets are optimised to provide the best possible crossover between the PS and
LS systems. The reference point for this adjustment is the front of each cabinet. (This means that the internal delays needed
to achieve a correct time alignment are set for cabinets standing next to each other with both fronts aligned). We recommend
that the system is adjusted so that arrivals from PS and LS are coincident at a fairly distant listening position.
7.1 Stacked LS and Flown PS
In the example below, r
1
being the distance from PS to listener position, and r
2
being the distance from LS to listener
position, the distance difference is then r
1
–r
2
(specified meters or feet).
r
1
> r
2
, the delay should be set on the LS NEXO TDcontroller channel.
r
1
< r
2
, the delay should be set on the PS NEXO TDcontroller channel
To convert the result in time delay (specified in seconds), apply:
t = (r
1
-r
2
)/C r
1
and r
2
in meters, C (sound speed) 343 m/S.
Set the units to meters, feet or seconds according to your preference). Delay will have to be adjusted according to the
distance difference r
1
–r
2
(see figure below).
