Thank you
The Yellowtec PUC² is a professional-quality USB soundcard for use
with MAC or Windows PCs. It is capable of recording high-resolution
audio at up to 192 kHz sample rate and 24 bit word-lenghts. The PUC
is designed after Yellowtec‘s standards of simple perfection. The idea
is to provide a high-quality soundcard with a plug n‘ play concept so
you can start using it right away. It provides a USB plug n‘ play option
for fast use plus the optional use of our ASIO* driver for the advanced
operator.
Several versions of the PUC are available, oering dierent audio input
and output formats and connections. The AES-3 interface is common to
all versions. For more information go to www.yellowtec.com and
check out our products.
Yellowtec has a policy of continually improving and updating it‘s
products. For rmware updates or dedicated software you should check
out our website from time to time. All updates will be free of charge.
Thank you

Ready, Set up, Go !
So what‘s in the box? Your PUC comes with a USB Y-Cord to interconnect with
your PC or MAC.
Simply interconnect PUC with your computer ( Mac / Windows/Linux ) using
the USB Y-Cord. Make sure both USB A-Plugs (yellow and black) are connected
to your PC. The yellow connector carries no data but will be needed to secure
sucient power supply.
When connecting the PUC for the rst time to your PC or Mac your system will
perform an automatic USB device installation. Your device will be identied
as YELLOWTEC PUC. (For using PUC with high-res audio (192KHz) you need to
install the ASIO* driver suite for windows from www.yellowtec.com)
The green Rdy LED will indicate a proper connection.
You can now use PUC in native mode.

PUC² Front Panel
AES 3 Input
The AES-3 input is the
default audio input to the
PUC². This input will overri-
de any other inputs when a
digital input carrier is detec-
ted and locked, even if there
is no active audio in the
digital stream. The audio si-
gnal is converted into a USB
format and available to any
audio recording application
on the computer.
AES 3 Output
The AES-3 output is
always active at the
sample rate selected
by the application
running the computer
ZLM LED
Red indicates„Zero
Latency Monitoring“
(See advanced ope-
rations)
ZLM Jack
In order to route the input
signal directly to the
output you can apply an
external contact closure.
This bypasses the OS ker-
nel for true Zero Latency
Monitoring.
AUX Output
The stereo 3.5mm jack
supplies an analogue au-
dio signal for monitoring.
It can be used to drive a
set of headphones, alt-
hough there is no control
of the AUX output level.
*Note that PUC Lite comes
without an AUX out.

LEA
Level Engine Automation (LEA)
The LEA Engine is a unique technology for levelling your interviews while recor-
ding. In comparison to standart AGC`s and Limiters the LEA engine knows to
excel by not creating artefacts or common pumping noises. Even with blanking
levels or loud ambient noise the LEA Engine works perfectly and levels smooth-
ly, just like an engineer inside your mic. The Engine also uses limiters to avoid
sudden lash outs and levels smoothly within (common volumes levels). It also
perfectly avoids raising noise oors during mute seconds of an interview.
The user himself doesn‘t need to bother with setups. All he has to do is start a
recording. The LEA Engine provides the freedom to solemnly concentrate on
the interview while guaranteeing to process your recording in the highest pos-
sible quality. *For the LEA software manual visit yellowtec.com/lea/download
