Hardware Connections

Audio Inputs
A dynamic microphone can be connected to the XLR input located on the rear panel, and an instrument such as a guitar or bass can 
be connected to the 1/4” input jack, also located on the rear panel  Each of these two inputs has an independent preamp featuring a 
dedicated gain control knob, and level and clip LEDs  Two analog RCA inputs are also located on the back panel  Signal from these 
inputs is mixed with the Microphone and Instrument inputs before being routed through the USB connection to a connected Mac  
or PC  
Audio Outputs
Connect the two analog 1/4” outputs (located on the rear panel of the KeyStudio) to powered monitors, an amplifier, or a mixer  You 
may also monitor through headphones by connecting one or two sets of headphones to the 1/4” stereo headphone outputs, located 
on the front panel 
MIDI Connections
In addition to the USB MIDI connection between KeyStudio 49i and your computer, you can connect the MIDI output of the 
KeyStudio 49i to an external MIDI device’s MIDI input  This enables you to control an external synthesizer or sound module via your 
computer, using the KeyStudio as a USB to MIDI interface, or as a standalone MIDI controller keyboard 
Other Connections
A sustain pedal can be connected to the 1/4” Sustain pedal jack on the back of KeyStudio 
Connecting KeyStudio 49i to a Computer
8
KeyStudio 49i functions as a class-compliant device, and your computer will recognize the keyboard without additional drivers  This 
gives immediate access to all audio inputs and outputs as well as to the built-in MIDI interface  As you become more familiar with the 
KeyStudio keyboard, you may wish to take advantage of this product’s additional professional features by installing the KeyStudio 49i 
drivers  
In Windows, these additional features include: using your new keyboard with more than one application at the same time (multi-
client), sending large SysEx messages, or using your KeyStudio 49i with Pro Tools M-Powered recording software or the included 
GM Module software   Installing the KeyStudio ASIO drivers in Windows also improves audio performance by reducing the time it 
takes for MIDI input (when using software synthesizers) or audio input signal to appear as audio at your computer’s outputs   
On a Macintosh computer, installing the M-Audio drivers enables you to use your KeyStudio 49i with Pro Tools M-Powered recording 
software 
The Windows and Mac OS X drivers are found on the KeyStudio 49i CD-ROM included with this package
