Staner is a Brazilian audio equipment manufacturer based in Presidente Prudente, São Paulo. Founded by Renato S. Silva, the company traces its origins to 1967, when Silva built an echo chamber that became the first device to carry the Staner name, and was formally established as Staner Eletrônica in 1973. The firm grew out of Silva's background in electronics repair and gradually shifted into full-scale production of professional audio gear for the Brazilian market.

The catalog spans more than 100 products, covering instrument amplifiers, power amplifiers, mixing consoles, loudspeaker enclosures, active speakers, microphones, and related accessories. Amplifier lines include the ShouT series for guitar and bass, the Ruby series, the Stage Dragon series, and the HD power amplifier line, alongside active PA speakers such as the SR-315A. Staner is also credited with introducing line array systems to the Brazilian pro-audio market and with early work on active loudspeakers with onboard amplification.

Staner sits at the center of a broader corporate group that has included ST-Com Electronic Components, Eros Loudspeakers, and the distributor Sonotec, reflecting its focus on domestic manufacturing and distribution. The brand is widely used in Brazilian rehearsal rooms, churches, schools, and small venues, where it is known more as a workhorse, value-oriented option than a boutique or export-focused name.

Staner has 8 products cataloged on Equipboard, including Bass Combo Amplifiers, Combo Guitar Amplifiers, and Power Amplifiers.
