The LS9 series consists of the 32-mic/line input 64-channel LS9-32, and the 16-mic/line input 32 channel LS9-16. Compact and light enough for one person to move and set up easily, it has features that have been field-proven in previous Yamaha digital consoles as well as outstanding sonic quality. In addition to an extensive range of gating, compression, and equalization capabilities, there's also a built-in USB memory recorder/player for recording or BGM playback, and other functionality that give you everything you need for small to medium scale live sound in remarkably compact, all-in-one consoles.
