Gain alignment
Gain Alignment
The objective of gain alignment is to ensure consistent sound pressure levels across the entire audience, regardless of whether coverage comes from main or fill function groups. The algorithm works by:
Making each beam in each function group equally loud across its respective target area.
Summing the levels of each beam within function groups.
Matching the summed levels of fill and LFE function groups with the main groups.
The alignment uses the following SPL frequency ranges:
Main and Fill groups: average SPL between 350 Hz and 3000 Hz
LFE groups: average SPL between 45 Hz and 90 Hz
EQ and Gain Alignment
EQ settings are taken into account during gain alignment. If you change your EQ settings after running alignment, you should re-run gain alignment to ensure the results remain accurate.
You can also run gain alignment without EQ active. Note that gain alignment is independent from the coverage beam target curve — the target curve does not influence the gain values calculated by the algorithm.
Headroom
The power headroom indicator shows the available headroom across the entire system. Exceeding available power headroom increases the risk of system clipping. If your headroom is exceeded after alignment, press the Normalize button to reduce levels and restore 0 dB power headroom.
