With 32 input head amps, the Yamaha LS9-32 can comfortably handle the complex and varied source requirements presented by a wide range of live sound applications, but it's always reassuring to know that you can expand it up to 64 channels by just adding external preamps and Mini-YGDAI interface cards for those extra demanding line-ups. No-compromise Analog Circuit Design Delivers the Best Sound in this Class 
The Yamaha PM1D digital mixing console and PM5000 analog console were acclaimed by leading sound engineers around the world for their stunning sound quality. The LS9 series consoles inherit the same type of superior sonic performance thanks to painstaking parts selection and detailed attention to the design of every circuit detail... right down to the power supply and grounding. Of course special attention has been paid to the critical head amplifiers with outstanding results. Intuitive Interface 
Each input channel features a 100-millimeter fader, ON/OFF key, CUE key, and 6-segment LED level meter that allow analog-style hands-on operation of the primary channel functions. Yamaha's popular Selected Channel interface allows smooth, intuitive access to the more detailed channel functions via a color LCD display and an array of logically arranged encoders. And no matter what display is showing, you can instantly return to the main display by simply pressing the HOME key. This interface has been refined and proven over many generations of Yamaha digital mixing consoles. Extensive Channel Functionality 
The LS9 consoles feature recallable head amplifiers that cover a wide 72-dB input range, phantom power, phase switching, a high-pass filter, 4-band full parametric equalization, panning with LCR capability...all the basics. But there's much more. You can choose from two EQ response types, and each channel features two dynamics processors that can be used for gating, compression, ducking, expansion, and even de-essing. There's even an attenuator (with boost) that makes it possible to take full advantage of the console's extra digital word length for extraordinary sound quality. Virtual Rack with Top-quality Effects 
There's no need for external effect racks with an LS9 console, both models provide a Virtual Rack that's packed with a complete range of effects that will cover just about any processing requirements. Up to 4 multi-effect processors can be used simultaneously, and you can use as many as 8 graphic equalizers. The internal effect library offers 48 preset effects... including the acclaimed REV-X reverb effects. In addition to the standard 31-band single-channel GEQ units, you also have 2-channel Flex15GEQ units that allow up to 16 15-point GEQ units to be used simultaneously. Both GEQ types allow convenient band adjustment via the console faders, and the channel ON keys can be used to instantly reset the corresponding band to zero boost/cut. Recall Safe and Recall Focus...Right Down to Head Amp Gain 
The LS9 scene memory allows instant store and recall of all console parameters, including head amp gain. The Recall Safe function can be used to exclude specified channels from scene recall operations, making it possible to leave sound effect or MC channels unaffected by scene recall, for example. There's also the Recall Focus function that makes it possible to specify which function group will be affected by scene recall: head amp, virtual rack, input patch, output patch, input channel, or output channel. USB Memory Recorder/Player for Convenient Recording and BGM or Effect Playback 
The LS9 consoles feature a built-in 2-track USB memory recorder and player that eliminates the need for external 2-track devices for many applications. It's easy to make live recording direct from the console, and it's also a convenient way to play background music or sound effects. The USB memory player is compatible with MP3, AAC, and WMA file formats at 96, 128, or 196 kbps. Detailed Access Management 
LS9 series consoles allow convenient, detailed access management, which can be especially important in fixed installations. User keys (standard USB memory devices) can be issued with different access levels for different users. Access can be controlled in detail, from full console to just a fader or two, as required. LS9 Editor Software for Enhanced Operability and Programmability 
The LS9 Editor is a free software viewer/editor application for Windows-based computers. It can be used online in real time for convenient, flexible metering as well as Selected Channel parameter display. LS9 Editor is also a great way to pre-program console setups offline for significantly enhanced efficiency. In permanent installations different operators can keep their own setups individually, and load them in the console as required via a USB memory device. The Editor program is also a great way to manage safe data backups. FREE SHIPPING IS ONLY TO CONTINENTAL US.
