In 2015, the Konsbud Audio delivered and installed the front linear sound reinforcement system (the d&b audiotechnik V series) for the main auditorium. The installation in Opera Nova is first such installation in Poland where the ArrayProcessing technology was used, which allows the increase the uniformity of sound coverage of the whole auditorium, so that all listeners experience the same hearing impressions.

In 2017 the linear sound reinforcement system in the opera was complemented with frontfill d&b audiotechnik T10 sets and additional V-GSUB low frequency sets. As part of the tender for the Scena Duża (Large Stage), the stationary d&b audiotechnik Yi7P and Yi10P type and the mobile MAX2 monitor sets were also provided, which ensure the performers have a proper listening experience during the performances. Three mixing consoles were delivered to the Opera Nova. On the Large Stage, the Avid S6L acts as a FOH console during concerts, and Allen & Heath dLive S5000 is used during opera spectacles.

As a part of the last investment the d&b audiotechnik front sound reinforcement system (which consists of 24S and V-GSUB sets), was delivered to the Chamber Stage. In addition, the sound engineers working in the Chamber Hall now have at their disposal the Allen & Heath dLive S3000 front console. Additionally, in 2017, the existing sound network was expanded, a wireless microphone system was delivered and the foyer sound reinforcement system was modernized with the Apart Audio devices.
