Oneal Áudio is a Brazilian manufacturer of professional audio equipment, founded in the 1990s and headquartered in Apucarana, in the state of Paraná. The company produces a broad catalog that spans passive and powered loudspeakers, subwoofers, line array systems, stage monitors, instrument combos (cubos) for guitar, bass, and keyboards, mixing consoles, Class D power amplifiers, signal processors, and installation speakers for commercial and environmental sound.

The brand is one of the larger domestic producers in Brazil's pro-audio sector, with a lineup that reaches well into the hundreds of SKUs and covers applications from live sound reinforcement and houses of worship to corporate AV and musical instrument amplification. Oneal is known in the Brazilian market for offering relatively long warranty terms on its gear and for designing products aimed at the mid-priced working-musician and small-venue segment rather than the high-end touring market.

Oneal Audio has 3 products cataloged on Equipboard, including Combo Guitar Amplifiers and Bass Combo Amplifiers.
