Yamaha is one of the largest musical instrument and audio companies in the world. They sell pianos, drums, guitars, motorcycles, jet skis, and a whole lot of pro audio gear — including their own line of microphones, plus the brands they own (Steinberg software, NEXO PA speakers, and others).
Yamaha’s pro audio division is enormous, but it’s built around digital mixing consoles (the CL, QL, and Rivage PM series), powered speakers, and recording gear. Microphones are real but smaller — both standalone Yamaha models and the YCM line aimed squarely at the streamer/podcaster market.
