At
Peachtree
Audio
we
think
products
should be
easy
to
use,
but
you
need to
know
a
few
things
before
setup.
The
Grand
Integrated's
USB
digital
input
ac-
cepts
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) Connect the USBterminal on the Grand Integrated to a USB connection on your
computer.
2) Your computer will "see" the
USB
Audio DAC inside the Grand Integrated.
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 24/192 playback on
a
PC.
Launch Music Program and play.
MAC
1) Open System Preferences.
2) Click
on
Sound.
3) In the Output tab 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
Grand
Integrated'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 useful 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 Grand Integrated volume knob
or
remote
control as the mastervolume control.
For critical listening to music from yourcomputer, avoid keeping multiple programs open.
It
can
compromise the sound quality and even cause signal dropouts.
Give the Grand Integrated adequate ventilation as it
may
get warm.
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
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 Grand Integrated
has been selected. Be sure
your
digital source is on and playing.
Be sure the Grand Integrated's standby button
is
glowing blue and that
your desired input is glowing blue. If the input button is blinking
the Grand Integrated is in "mute" mode. Press the mute button on
the remote to un-mute the Grand Integrated. Check to be sure your
digital cable is properly connected.
Please check the batteries by removing the cover on the back ofthe
remote. It is an infrared remote so it needs a clear line of sight to the
sensor on the front panel of the Grand Integrated.
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 Grand Integrated, wait a few sec-
onds, then reconnect. These are computer hookups, and sometimes
you'lllose a signal just as with your printer or other USB device.
You
should not have this problem often. We designed the Grand Integrated
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 Grand Integrated. If it works properly, with no noise, then the
computer
in
your office is introducing a ground loop into the system.
This is not uncommon. However, the Grand Integrated's digital inputs
are transformer-coupled to minimize this problem. If a problem
persists, please feel free to contact Peachtree Audio.
Sometimesthis
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 Grand Integrated 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.
