computer to the decco65's digital USB
input-
we think you're going to love
what you hear from your music library from compressed music files to high

your high end digital music sys-
tem. The decco65 combines a high quality, high resolution DAC, a terrific
65wpc amplifier, and a state-of-the-art hybrid tube preamp and head-
phone amp. Both analog and digital sources will sound exceptional.
This manual
is
a guide to the functions of your decco65.
It
shows you how
to connect both digital and analog sources, and offers tips on getting the
best performance. The ability
to
mate with virtually any digital source, while
providing superior sound makes the decco65 a special product. It's one we're
proud to offer. We sincerely hope the decco65 provides you with years of
enjoyable music listening. Visit our website at www.peachtreeaudio.com for

At
Peachtree Audio
we
think
products should be
easy
to use,
but
you need to
know
a few things before setup.
The
decco65's
USB
digital input accepts music
files from
your
computer's
hard drive and plays them
back
with
superb
fidelity.
See
instructions below.
Some
minor
changes
may
occur
with
Windows
or
Apple
OS
updates,
but
the
basics are
the
usually the same.
USB Connections
PC
1) Connectthe USB terminal on the decco65 to a USB connection on your computer.
2) Your
computer
will "see"
the
USB
Audio DAC inside the decco65. You might
get
a pop-up
box
noting a
new
USB
connection.
3)
Right click the
speaker
icon on
the
bottom
of
your
screen.
4) Select "Audio" tab.
5) Using the drop-down
box
choose
the
USB
DAC.
6) Click OK.
7) You will need to install the included
CD
software
download
for
24/96
playback
on a PC.
Launch Music Program and play.
Mac
1) Open System Preferences.
2) Click on Sound.
3) In the Outputtab you should see USBAudio DAC (or similar) as one ofthe choices.
4) Select it.
Launch iTunes and
enjoy
your
music.
Once
you
set
up
your
computer
following the
above
instructions it should recognize the
decco65's
USB
Audio
DAC
and default
to
it. If you unplug
the
USB
connection you,
may
have to repeat
some
steps; this is not unusual.
Other usefu
I tips...
For the best sound when listening to music from your computer, set your computer and music
program volume controls to maximum and use the decco65 volume knob
or
remote control as
the mastervolume control.
-Forcritical listening to music from your computer, avoid keeping multiple programs open.
It
can
compromise the sound quality and even cause signal dropouts.
Give the decco65 adequate ventilation as it
may
getwarm.
We'll post articles and other helpful tips on getting the best sound from your computer's music
files, your iPod, and your other digital music sources. Visit us at ourwebsite:

Check to
be
sure that both the power switch
on
the back panel and the
standby switch
on
the front panel are
on.
The front panel light should
be
blue.
It
is
green when
in
standby.
Be sure your system is not muted and that the decco65 has
been selected. Be sure your digital source is on and playing.
Be sure the decco65's standby button
is
glowing blue and that your
desired input is glowing blue. If the input button is blinking the
decco65
is
in
"mute" mode. Press the mute button
on
the remote to
un-mute the decco65. Check to be sure your digital cable
is
properly
connected.
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 decco65. Check that no light
sources, like lamps, are interfering with the infrared remote signal.
First, try relaunching your music server program (iTunes,
WMP,
etc.).
If
your computer still doesn't recognize the USB DAC unplug the USB
cable from the computer and the decco65, wait a few seconds, then
reconnect. These are computer hookups, and sometimes you'll lose a
signal just as with your printer or other USB device.
You
should not
have this problem often.
We
designed the decco65 to remain locked
on
the USB signal at all times, but signal dropouts are still possible.
This can require some trial and error diagnostics. If
you
have music
files available
on
a laptop computer connect
it
(while
on
battery power)
to
the decco65. If it works properly, with no noise, then the computer
is
introducing a ground loop into the system. This is not uncom-
mon. However, the decco65's digital inputs are transformer-coupled
to minimize this problem. If a problem persists, please feel free to
contact Peachtree Audio.
Sometimes this
is
from static buildup but
it
should not occurconsistently
over a long period of time. Contact yourdealeror
Peachtree
Audio
if
this
persists.
The amplifier
in
the decco65 will shut down if it experiences an
unusually large power surge or overheats due to a short, or very
loud volumes over a long period of time. This
is
a protection circuit.
Turn down the volume. The amplifier should come back on after a
while.
Over
90°/o
of the time this is due to a software malfunction on your
computer. Shut down all music server programs and check to be
sure that the Peachtree DAC is chosen as the digital output device
by your computer. If you have trouble finding
it,
then unplug the
USB
from
the
decco65
and plug it
back
in 5
seconds
later.
It
almost
always shows up after that. Then re-launch your music
server program(s) and select a song.
