7.5 Aligning RS with main system
The NEXO TD Controllers factory presets are optimised to provide the best possible crossover between the RS15 and RS18
and other NEXO main systems. These crossover algorithms are defined for speaker acoustic reference points being aligned.
The acoustic reference point on all NEXO products is the front of each cabinet, therefore:
• RS reference point in Omni Mode is center of the front grid
• RS reference point in Directional Mode is center of the face opposite to connector panel
REFERENCE POINT IN OMNI MODE REFERENCE POINT IN DIRECTIONAL MODE
7.5.1 Alignment with distance measurement
The fastest way to align RS arrays to a main system is simply to measure distance difference from listening point to RS and
main system reference points.
r1 being the distance from main array to listener position, and r2 being the distance from RS to listener position, the distance
difference is then r1–r2 (specified meters or feet).
r1 > r2, the delay should be set on the RS TDcontroller channel.
r1 < r2, the delay should be set on the main system TDcontroller channel
t = (r1-r2)/C gives conversion from distance to delay r1, r2 in meters, C = 343 m/s.
NEXO recommends that main system and subwoofer systems are adjusted so that arrivals from RS and main system are
coincident at a fairly distant listening position (mixing position or further).
Because of proper acoustic reference point definition in NEXO TDControllers DSP setups, this method is highly reliable.
