Thank you for purchasing the Peachtree Audio decc02 amplifier.
While Peachtree Audio is anew company, the people behind the
design and marketing of this fine product have been
in the Consumer
Electronics business over 30 years. The decc02 will process ahost
of digital audio sources from the Slim Devices Squeezebox,
to the
Sonos ZP90,and many more including the digital output of your CD
player. The design of the decc02
is an attempt to marry audiophile
level amplification with the unique capabilities of external Digital to
Analog converters. The ability to process and play compressed and
uncompressed music files that have been downloaded to hard drives
makes the decc02 aunique product. The fact that it vastly improves
upon the performance of most computer-audio systems
is abig plus;
and our original goal.

Make sure the on/off switch on the front panel is en-
gaged. Check to
be sure the AC plug is connected. Check
the fuse.
Be sure you have the proper input selected. Make certain
the mute isn't engaged. Determine
if your source is on. If
the input button is blinking then your digital signal is not
locked. Check your cable for connections and your
source
to be sure it is on and playing.
Please check the batteries by removing the cover
on the
back
of the remote. It is an infrared remote so it needs a
clear line
of sight to the sensor on the front panel of the
Decc02.

The first thing to try is rebooting the music server
program (iTunes, Foobar,
WMP, etc) and see if that works.
Then try turning the Decc02
off, then re-boot your com-
puter. Then turn
the Decc02 back on. If the computer still
doesn't recognize the USB DAC repeat the process and
also unplug the USB cable from the computer and the
Decc02, then plug
it back in right before re-booting.
These are computer devices, and sometimes you'll lose a
signal just
like your printer or any other USB device.
You should not have this problem often. We designed the
Decc02 to remain locked
on the USB signal at all times, but
sometimes you
can still get asignal dropout.
This can require some trial and error diagnostics.

If you have music files stored on alaptop computer, hook it
up to the Decc02 and apair of speakers using battery pow-
er. If it works properly with no noise then your computer in
your office is introducing aground loop in to the system.
This
is not uncommon; but the Decc02 has transformer
coupled digital inputs to minimize this problem.
If problems
persist, please feel free to contact Signal Path.
Sometimes this
is from static buildup but it should
not occur consistently over along period
of time.
Contact your dealer or Signal Path
if this persists.
You must use awide bandwidth 75 ohm digital intercon-
nect
in this application. If you use astandard audio RCA
cable the results will not
be nearly as good. This is not an
unusual mistake
as the two interconnects look identical but
sound different.

Your iPod offers custom equalizations for headphone
use that aren't necessary with the Decc02 and agood
pair of speakers. Use a"flat" response and be sure the
iPod volume
is set to match the other components in
your system. If you find that you still need equaliza-
tion, then start
at "flat" and make your settings from that
point.

At Peachtree Audio we think that products should be easy to use. Therefore,
we don't require any custom USB drivers or software programs in order to listen
to your music from your computer. The Decc02's USB audio input is used
to take
music files from your computer's hard drive and play them back with superb fidel-
ity.
While some of the wording and steps vary somewhat between MACs and PCs,
the basic instructions are very similar.
USB Connections
PC
1) Connect the USB terminal on the Decc02 to aUSB connection on your computer.
2) Your computer will "see" the USB Audio DAC inside the Decc02. You may get a
"USB AUDIO DAC" pop-up box but it's not necessary.
3) Right click the speaker icon on the bottom of your screen
4)Select "Audio" tab
5) Using the drop-down box choose USB AUDIO DAC
6)Click OK
7) Launch Music Program and play
Mac
1) Later Mac setup may vary but the basic instructions are outlined below
2) Click on to System preferences
3) Click
on to the speaker icon
4) Under the sounds tab you should see awindow that offers USB Audio DAC (and
your soundcard) Click
on to USB Audio DAC
5) Launch Music program and enjoy your music
Once you do this setup your computer should recognize the USB Audio DAC and
default to it when plugged in.
If you unplug the USB connections and reboot your
music before re-connecting first, you may find that you have to go back through
steps 3-7, This
is not unusual.
••••

1) Always set your computer and Music program volume control to
maximum and use the decc02 volume as amaster control. It sounds
better that way.
2) Avoid keeping multiple programs open while streaming music. It can
compromise the sound quality and even cause signal dropouts.
3) Avoid plugging and unplugging the USB input multiple times in ashort time span. It usually
is not aproblem but increases the chance of avoltage spike to the USB input.
4) Give the decc02 adequate ventilation as it will get fairly warm.
5) The blue lighted ring around the digital inputs of the decco2 have adiagnostic built in. If the
digital signal is not locked on the DAC it will continue
to blink. Check your connections and
be sure your source is turned on and playing. If it still blinks with no sound feel free to call
us at the number below.
As we develop more computer-audio products and gain more knowledge
we'll post helpful tips on our website:

@Iterested in the Green Movement?
1) The decc02 meets the European RoHS standards for non-hazardous metals
2) The veneers in the decc02 cabinet come from sustainable forests with the FSC certifica-
tion
3) The decc02 utilizes astandby transformer that draws less than awatt
in the US and less
than 2watts
in countries with 220V electrical service
4) We will continue to investigate more ways of making our products environmentally friendly
as
we develop Peachtree Audio into afull line. Feel free to e-mail us with your sugges-
tions.

•Co Axial Digital Inputs: From the Back panel connect the input
with adigital coaxial cable (7 or 1a on the "Back Panel" page)
to the coax output from any coaxial digital source.(CD and DVD
players, Sonos modules, Squeezebox modules, cable box, etc
..
etc .. )Select the corresponding input in the front of the decc02.
•Optical Digital Inputs (sometimes called Toslink): From Back
panel connect the input with an optical cable
(8 or 9on the "Back
Panel" page) to the optical output from any optical digital source (CD
and DVD players, Sonos modules, Squeezebox modules, cable box,
Apple Airport, Apple TV) Select the corresponding input on the front
of the decc02.
•USB Input for Computer: While both the decc02 and your computer are "On", connect aUSB
cable
from your PC t6 the back of the decc02 (# 6on the "Back Panel" page). On the bottom right corner
of your computer screen, you'll see aspeaker icon. RIGHT CLICK this icon and select "Adjust
Audio Properties". Follow the "Volume" tab. Next to the speaker icon
in the volume tab, use the
drop-down tab and select USBAudio DAC.
You are now ready to launch and play yourfavorite mu-
sic server program like iTunes or Windows MediaPlayer, although there are many more to choose
from. Be sure you have the USB input selected on your decc02. Also
be sure you make the USB
connection before launching the music server program.
•USB for Mac: While both your Mac and decc02 are in the "On" position, connect aUSB
cable from your Mac to the USB input on the back of the decc02 (# 6on the "Back Panel"
page)
.. ln the "Systems Preferences" choose the speaker icon. When the next box appears,
switch from "Internal Speaker" to "USB Audio Device". You are now ready to launch and play
your favorite music server program like iTunes although there are many more to chose from.
Be sure you have the USB input selected on your decc02. Also be sure you make the USB
connection before launching the music server program.
•Analog Connections: The analog hook ups are for using conventional components like
Tuners, Tape Decks, SACD players, etc. If you plan to use aturntable, you'lI need an external
phono preamp to match your cartridge output. Consult your dealer for recommendations.
•Speaker Output: The decc02 is designed to drive one pair of speakers between 4and 8ohms.
It is notadvisable to use more than one pair of speakers with the decc02.
•Pre Out: The Pre out can be used for several operations:
Subwoofer output:
Run astereo pair of RCA cables from the pre-out (#14 on the "Back Panel" page) to the sub-
woofer line-in. If your subwoofer has only one line-in, you can use asingle RCA connection
from either channel. Almost all music information below 1aaHZ is mixed in
mono so it will not
make asonic difference. This single line RCA type plug will then be connected to the single
input on your subwoofer.
External Amplifier: Connect the Stereo RCA cable from the pre output of the decc02 to the
stereo RCA inputs on your external amplifier. Connect the speaker wires to the speakers.
Turn on the decc02 and then the external amplifier. At this point, you'll be using the decc02
as aDigital and Analog Preamp.
External Amplifier and Powered subwoofer: You will need to split tl-,e LJR outputs to two
L/R outputs.
To do this, you'll need to purchase 2-Y-Adapters (Single Male to Two Female).
Plug the YAdapters into the pre-out of the decc02. You
now have two outputs for each chan-
nel. Connect 1set of L/R RCA type connectors to the external
amp and the other two outputs
to your subwoofer.
•Using decc02 as an external DAC: Connect the "Fixed" line out from the dec co2 to an
Aux input of your receiver or preamp.
Connect any digital input to the decc02 as described above. Select the connected
digital input
on the decc02, then select the input on your Preamp/Receiver that is con-
nected to the decc02's line output.
WARNING: DO NOT CONNECT THE decco2 "FIXED" LINE
TO APHONO INPUT. THIS
WILL OVERDRIVE YOUR PREAMP AND YOU
MAY DAMAGE YOUR PREAMP/RECEIV-
ER AND OR SPEAKERS.
