INPUTS INPUTS
The pcDIQ is a four-channel version of Whirlwind's popular pcDI
stereo line interface, in a 1RU rack mount enclosure. Multiple
computer audio outputs, MP3 players, CD players or other
consumer audio devices can be converted to mic level for mixing in
a traditional audio console.
Each of the four channels has unbalanced stereo line level inputs
that are converted to left and right balanced, mic level XLR outputs.
Input connections include gold plated left and right RCA jacks on
the rear panel, with left and right ¼” tip-sleeve jacks and a 3.5mm
stereo jack on the front. Plugging a source device into the front
panel jacks disconnects the rear panel RCA inputs. Additionally, the
eight ¼” inputs allow the pcDIQ to be used as an eight channel
direct box to convert line level audio for recording or live
performance purposes.
The pcDIQ also features a separate stereo mix buss that combines
the four channels into a single stereo mic level, balanced output.
Each of the channels of the pcDIQ can be selectively assigned to
the mix buss through a switch. The individual channel can be output
in mono while the mix buss signal remains in stereo. An additional
switch converts the mix buss output from stereo to mono.

Front Controls and Connections
Each channel has four switches to modify the signal inserted into any of the
input jacks.
MIX switch applies the left and right input signals to the mix buss.
GROUND / LIFT switch breaks the audio ground between the input
connectors and the XLR output.
MONO /STEREO switch combines the left and right input signals to mono
and sends the sum to both outputs. Signals applied to the mix buss are
unaffected.
PAD switch applies 20dB of attenuation to the input signal to control source
devices with high output levels, if necessary.
TIP-SLEEVE ¼” input jacks allow individual access to the eight channels of
high to low conversion and disconnect both the rear panel RCA and the
3.5mm stereo inputs when used.
3.5MM STEREO jacks provide convenient connection of MP3 players and
other audio devices that use the 3.5mm format. The tip is wired to the left
channel and the ring to the right. Using these jacks disconnects the rear
RCA inputs.
MIX OUTPUT MONO/STEREO switch determines whether the mix output
is separate left and right signals or a combined mono signal from both jacks.

Rear Connections
CHANNEL OUTPUT XLR connectors deliver mic level outputs from
the individual channel inputs. The channel MONO/STEREO switches
determine if the output is separate left and right signals or a combined
mono signal from each jack.
RCA INPUT jacks allow convenient connection of rack mounted
source devices with unbalanced outputs. Using the front panel inputs
disconnects the rear panel RCA inputs.
MIX OUT XLR connectors deliver the mic level sum of any of the inputs
assigned to the mix buss. The mono/stereo switch determines
whether the mix output is separate left and right signals or a combined
mono signal from both jacks. The balanced output signal is across
pins 2 and 3 of the XLRs. The pin 1 ground is permanently lifted from
the MIX OUT connectors to reduce the possibility of multiple ground
loops in the signal paths.
