Recording and Playback with Computer 

• On your Windows PC, the driver automatically 

installs when you connect and power up the device. 

Note: Restart your computer to activate the driver.

• Windows will manage the device through the 

Device Manager utility for setting recording and 

playback levels and functionality. The KM-112 is a 

“USB Multimedia Device,” allowing you to select 

the device and control input and output levels for 

recording and playback.

• There is a front panel switch (see page, “Front Panel 

Operation and Functions,” item number 9) to choose 

whether the KM-112 will function as an Audio 

device (mixer) and work with the audio in signals 

(see rear panel information above), or work as a com-

puter interface, allowing you to record your vocals 

through the USB connection to your Windows 

computer.

• If you have computer files that have had vocal 

tracks removed, or came without vocals, you can 

record your own vocals and overdub the instru-

mental tracks. Commercial and shareware/freeware 

multitrack recording software will allow you to re-

cord and save tracks in various digital file formats.
