The LS9-32 has a total of 33 faders and the LS9-16 has 17. The LS9-32 faders control the 32 inputs and stereo output, while the LS9-16 faders control the console's 16 inputs and stereo output. Since the LS9-32 can handle a maximum of 64 channels while the LS9-16 can handle a maximum of 32 channels, both models feature switchable channel layers with the second LS9-32 layer allowing direct control of channels 33 through 64, and the second LS9-16 layer providing access to channels 17 through 32. Input sources can be freely patched to the channels as required, and a single source can be patched to two channels, for example, with one in the first layer being used for front-of-house feed and another in the second layer for monitoring. Direct LAYER keys allow instantaneous switching between layers. Both consoles also feature four stereo inputs. When you consider the compact dimensions of these consoles, this much input capacity and versatility is a remarkable accomplishment.

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 he console's extra digital word length for extraordinary sound quality. No analog console has ever offered this amount of control.

The LS9-32 has 16 analog "omni" XLR outputs on the rear panel, while the LS9-16 has 8. For easy expansion the LS9-32 has two Mini-YGDAI cards slots, and the LS9-16 has a single slot. The expansion slots make it easy to expand the consoles with high-quality analog I/O, or digital I/O in a range of formats. The 16 mix buses can function in either AUX (VARI) or GROUP (FIX) mode. When the AUX (VARI) mode is selected the send point can be set PRE EQ, PRE FADER, or POST FADER. 8 matrix buses are provided in addition to the mix buses, and these can be used for side fill or recorder sends, or anywhere additional sends are required. For easy, efficient monitor mixing a SENDS ON FADER feature instantly assigns to send levels to the consoles faders. The output busses feature many of the same functions as the input channels, including 4-band full parametric EQ and dynamics, for extended output processing capability.

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 �c 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.

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.
