Useful Tips
At Peachtree Audio we think products should be easy to use. No custom USB
drivers are needed for Mac OS. Windows PCs do not comply with USB
2.0 standards so single driver is needed to insure 24/192 streaming. The
DAC•iTx’s USB digital input accepts music files from your computer’s hard
drive and streams from internet radio Apps like MOG, Pandora, RDio, and
Spotify.
USB Connections
PC 5HPHPEHUWRGRZQORDGWKHSURYLGHG86%GULYHUÀUVW
1) Connect the USB terminal on the DAC•iTx to a USB connection on your
computer.
2) Your computer will “see” the USB Audio DAC inside the DAC•iTx. You may get a
“Peachtree 24 192 USB X” pop-up box but it’s not a requirement for connection.
3) Right click the speaker icon on the bottom of your screen.
4) Select “Audio” tab.
5) Using the drop-down box choose “Peachtree 24/192 USB X”.
6) Click OK.
7) Reminder: You must download the enclosed driver on your PC in order to play
back high resolution files.
Mac
1) Open System Preferences.
2) Click on Sound.
3) In the Output tab you should see “Peachtree 24 192 USB X” as one of the
choices. Select it.
4) Select it.
Launch iTunes and enjoy your music.
Once you set up your computer following the above instructions it should
recognize the DAC•iTx’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.

2) Avoid plugging and unplugging the USB input multiple times in a short time
span. It usually is not a problem but increases the chance of a voltage spike
to the USB input.
Other Useful Tips
1) For critical listening to music from your computer, avoid keeping multiple
programs open. It can compromise the sound quality and even cause signal
dropouts.
We’ll post articles and other helpful tips on getting the best sound from
your computer’s music files and your other digital music sources. Visit us at
our website: www.peachtreeaudio.com.
Interested in the Green Movement?
1) The DAC•iTx meets the European RoHS standards for non-hazardous metals.
2) The DAC•iTx utilizes a standby transformer that draws less than a watt in the US
and less than 2 watts in countries with 220V electrical service.
3) We will continue to investigate more ways of making our products environmentally
friendly. Feel free to email us with your suggestions: [email protected]

Tr o u b l e s h o o t i n g
The DAC•iTx will not
turn on
The DAC•iTx turns on
but there is no sound
Be sure the DAC•iTx’s external power supply is connected to the rear
panel DC input and that the power supply is plugged into a live AC
outlet.
Be sure your system is not muted and that the DAC•iTx has been
selected. Be sure your digital source is on and playing. Be sure
the DAC•iTx’s standby button is glowing blue and that your desired
input is glowing blue. If the input button is blinking the DAC•iTx is
in “mute” mode. Press the mute button on the remote to un-mute the
DAC•iTx. Check to be sure your digital cable is properly connected.
The remote control
doesn’t work
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 DAC•iTx.
You intermittently lose
your signal on the
USB input
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 DAC•iTx, 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 DAC•iTx to remain locked
on the USB signal at all times, but signal dropouts are still possible.
You pick up hum and noise
through your DAC•iTx in your
office system
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 DAC•iTx. 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 DAC•iTx’s digital inputs are transformercoupled to minimize this problem. If a problem persists, please feel
free to contact Peachtree Audio.
When you switch from one
source to another you get a
loud “click” or “pop”
Sometimes this is from static buildup but it should not occur consistently
over a long period of time. Contact your dealer or Peachtree Audio if this
persists.
Your coaxial digital connections
do not sound quite right
You must use a wide bandwidth 75 ohm digital interconnect in this
application. If you use a standard 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 doesn’t sound quite
right through the DAC•iTx
You get dropouts or no sound
when streaming 24/192
10
Your iPod offers custom equalizations for headphone use that aren’t
necessary with the DAC•iTx and a good pair of speakers. We recommend
using a “flat” response. If you find that you still need equalization, then start
at “flat” and make your settings from that point.
The digital inputs of the DAC•iTx are capable of 24/192 streams
in bench test conditions; however some sources may present
problems from excess jitter, poor grounding or a number of other
potential problems. Please call Peachtree Technical Service if this
occurs. 704-391-9337
