INPUT(RCAphonojacks X2and 3.5mm
stereo TRS jack) Use to connect the
audio outputs of computer sound
cards,CDplayers,tapedecks,etc.The
RCA phono jacks are color coded – red

in stereo applications. The 3.5mm
(1/8”) jack is a tip/ring/sleeve type.
The tip is common with the + side of
the white RCA phono, the ring is
common with the + side of the red RCA
phono jack and the sleeve is common

impedance, mic level signals suitable
for connection to balanced, low-Z
equipment (mixing console,
workstation, etc.) The output signal is
attenuated approximately 20dB below
the input level. These jacks are color
coded to match their corresponding
inputs.
Whirlwind will, at its
option, repair or replace

modifications or use of the
product in unintended
applications.
PAD(SwitchX2)
Most instruments will operate
properly when set to the “O”
position. Set to the “I” position
(adds 20dB attenuation to the input
signal) for use with very “hot”
signals to reduce the possibility of
distortion.
GND/LIFT(Switch)
This switch is usually left in the
“GND” position (grounds are
connected from input to output). If
hum occurs in either channel when
using the pcDI, setting the switch to
the “LIFT” position may help to
reduce it. (This disconnects the
ground between BOTH inputs and
thecorrespondingXLRoutputs.)
STEREO/MONO(Switch)
Whenplaced inthe STEREOposition,
the pcDI acts as two separate and
independent DIs. In the MONO
position, the left and right input
jacks are summed into a mono signal
