Achieving Greater Low End Impact with Arraycalc

Explore the technical process of time-aligning subs with the main PA for an improved audio experience.

Key Points:
  • Focus on aligning the subs with the main PA. This involves a different approach than aligning the mid-high cabinets, emphasizing the importance of the phase response between the mains and the subs.
  • Emphasis is placed on the crossover region, which is the frequency range where the tops and subs interact. The team from d&b explain the significance of this region, particularly focusing on frequencies between 50 and 110 hertz.
  • The process of adding delay to either the sub array or the entire sound system is demonstrated, including troubleshooting steps when the initial results are not satisfactory.
  • See the technique of adding delay to the entire sound system to align the subs, ensuring that the tops' alignment remains unaffected.
  • Learn how to achieve as close an alignment as possible between the phase traces of the subs and the mains, keeping the phase difference within 90 degrees.
  • A crucial aspect discussed is the selection of the test point for measurement, ideally positioned equidistant from the subs and the mains, approximately two-thirds into the room.
  • See a realistic approach to sound alignment, acknowledging that perfect time alignment is not always possible for every audience member. The goal is to achieve the best alignment for the majority of the audience.

Gain essential guidance for audio engineers to optimize the performance of your sound systems by effectively aligning tops and subs, ensuring a powerful and cohesive audio experience.
