The PM series of analog mixing consoles
The first PM mixer manufactured by Yamaha was the PM200. Introduced in 1972, it was a monaural mixer with unbalanced inputs and outputs
The PM400 was an upgraded mixer with a stereo bus and balanced inputs and outputs.
The Yamaha PM1000 mixing console was a significant product in the professional audio industry because of its many advanced features and reasonable price. Introduced in 1974 it incorporated many innovative features such as a modular design using channel strips and output strips, a 4 bus design, and an output matrix mixer. Because it was manufactured by an established company it was readily accepted in many audio industries including sound reinforcement, recording, and audio for video. It also established a reputation for being rugged in the often abusive environment of touring sound reinforcement.
The PM2000 featured a hard chassis construction for rigidity and durability on the road.
"One of the tests we are still using is our 'flight case test'. During prototyping we order a custom flight case - not even a very sturdy one - and place the console in it. The flight case is stood on end, and then tipped over in both directions and allowed to fall to the floor. If the console powers up immediately and works flawless after that ordeal, then it passes the test."
The PM3000 was the first mixer to use voltage-controlled amplifiers (VCAs) in a mixer designed specifically for sound reinforcement. It used a custom VCA design using discrete hybrid ICs
The PM4000 introduced stereo auxiliary buses and fully parametric Equalization on the input channels.
The PM5000 was a hybrid analog mixer with a digital control system which provided scene recall.
