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.
