Pentacústica is a Brazilian manufacturer based in Varginha, Minas Gerais, that builds technical infrastructure products for the pro audio, video, lighting, and IT markets. The company organizes its catalog around three product divisions: energy (power distribution units, power managers, AC cables and connectors, and rack-mount power strips such as the PSG series and the PM1.1 and PM1.2 power managers), connectivity (data and signal cables, patch panels, and network hardware built for demanding environments), and hard cases (19" rack cases, trunk-style road cases, and briefcase-style enclosures for transport and storage).

The brand's focus is on the unglamorous backbone of a working signal chain — clean power, reliable connections, and protective housings — rather than on instruments or signal processors. Its products are common in Brazilian recording studios, broadcast facilities, live-event rigs, and data-center installations, where the emphasis is on durability and continuous operation.

Pentacustica has 3 products cataloged on Equipboard, including Power Conditioners and Bags, Cases & Covers.
