Introduction
Safety Guidelines
In the bottom right corner of your screen, you’ll see a speaker icon. RIGHT CLICK this icon and select “Adjust
Audio Properties”. Follow the “Volume” tab.
Beside the speaker icon in the volume tab, use the drop-down tab and select USB Audio DAC.
You are now ready to launch and play your favorite music server program like iTunes or Windows Media although
there are many more to chose from. Be sure you have the USB input selected on your Nova
• USB for Mac: While both your Mac and Nova are in the off position, connect a USB cable from your Mac to
the USB input on the back of the Nova (6). Turn on the Nova and then boot up your Mac. (same thing…both
units can be on….you just can’t have the music server program open before you connect the USB)
In the “Systems Preferences” chose 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.
• Analog Hookup: The analog hook ups are for using conventional components like Tuners, Tape Decks,
SACD players etc.
If you plan to use a turntable, you’ll need an external phono preamp to match your cartridge output. Consult your
dealer for recommendations.

• Speaker Output: The Nova is designed to drive one pair of speakers between 4 and 8 ohms. Is is not advisable
to use more than one pair with the power from the Nova
Technical Specifications
It can first be used as a subwoofer output. Run a stereo pair of RCA from the pre-out (14) to the subwoofer
line-in. If your subwoofer has only one line-in, you can use a Y Adapter at the Nova (Dual Male to Single Female)
which will give you a summed single output. This single line RCA type plug will then be connected to the single
input on your subwoofer.
Trouble Shooting
• External Amplifier and Powered subwoofer: You will need to split the L/R outputs to two L/R outputs. To
do this, you’ll need to purchase
Product Guarantee and Service
• Pre Out: The Pre out can be used for several operations.
• External Amplifier: Connect the Stereo RCA type cable from the pre output of the Nova to the stereo inputs
on your external amplifier. Connect the speaker wires to the speakers. Turn on the Nova and then the external
amplifier. At this point, you’ll be using the Nova as a Digital and Analog Preamp.
2-Y-Adapters (Single Male to Two Female). Plug the Y Adapters into the pre-out of the Nova. You now have
two outputs for each channel. Connect 1 set of L/R RCA type connectors to the external amp and the other
two outputs to your subwoofer.
• Using Nova as an external DAC: With your existing system, connect the “Fixed” line out from the Nova to
an Aux channel of your receiver or preamp. Hook any Digital inputs to the Nova as described above. Select
the connected digital input on the Nova, then select the input on your Preamp/Receiver that is connected the the
Nova’s line output.
WARNING: DO NOT CONNECT THE NOVA “FIXED” LINE TO A PHONO INPUT. THIS WILL OVERDRIVE YOUR
PREAMP AND YOU HAVE A GOOD CHANCE OF DAMAGING YOUR PREAMP/RECEIVER AND OR SPEAKERS.

Introduction
1)
Always set your computer and Music program volume control to
maximum and use the Nova volume as a master 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 a short time span. It usually is not
a problem but increases the chance of a voltage spike to the USB input.
4)
Give the Nova adequate ventilation as it will get fairly warm.
5)
The blue lighted ring around the digital inputs of the Nova have a diagnostic 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.
Thank you for purchasing the Peachtree Audio Nova amplifier.
While Peachtree Audio is a new company, the people behind the design and marketing of this fine product have been in the Consumer Electronics business over 30
years. The design of the Nova 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 Nova a unique product. The fact that it vastly
improves upon the performance of most computer-audio systems is a big plus; and
our original goal.
As we develop more computer-audio products and gain more knowledge
we’ll post helpful tips on our website:
Signalpathint.com
704-391-9337
This manual is your guide to the functions and connections associated with the
Nova. It will process a host of digital audio sources from the Apple Airport to the
Slim Devices Squeezebox, to the Roku Soundbridge, to the Linksys Music Bridge,
to the Sonos ZP80, and to the digital output of your CD player. And of course, you
can plug an iPod in to it, too.
We sincerely hope that the Nova provides you with years of trouble-free music
listening, and that you will use it often. We will try to keep updates on our website, http://signalpathint.com/index.htm , and you may also want to contact your
dealer should you have any questions. While you’re thinking about it, please go to

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 Nova’s USB audio input is used to take music files from your computer’s hard drive and play
them back with superb fidelity.
While some of the wording and steps vary somewhat between MACs and PCs, the basic instructions are very similar.
USB Connections
1)
PC
Connect the USB terminal on the Nova to a USB connection on your computer.
2)
Your computer will “see” the USB Audio DAC inside the Nova. 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
1)
Mac
Later Mac setup may vary but the basic instructions are outlined below
2)

13) Aux 2: for analog line level sources
*The Home Theater Bypass is used when you want to integrate the
Nova in to a Home Theater system that has Preamp outputs on the surround processor.. First you should turn down the volume. Then you
take the Front left and Right preamp outputs from your Home Theater
processor and plug them in to the Aux3/HT Left and Right inputs. Next
you activate the HT button next to the Aux3 input. At this point you are
bypassing the preamp stage of the Nova and using the Nova’s amplifier
to power your left and right front speakers in your home theater. You
will also have 2 Aux inputs for analog sources such as an iPod or a CD
player. This feature allows you to have a large number of digital inputs
integrated in to your Home Theater setup.
14) Preamp output: to connect the Nova to an external amplifier or to a subwoofer. The Nova amplifier is still active
when the preamp output is used.
15) Digital filter slope: user selectable DAC filter slopes allow for a sharp slope which measures better and a soft slope
that is preferred by many audiophiles.
The equipment should be packed in its original packing and returned to the dealer from whom it
was purchased, or if unavailable, directly to the Nova distributor.
You should use a reputable carrier….Do Not Send By Postal Service. . Signal Path cannot accept responsibility for the Nova while in transit to the dealer, distributor, or service facility.

*The lighted rings around the digital input
buttons will blink until the digital signal is
locked on the DAC
Trouble
Shooting
The Nova will not turn on
Make sure the on/off switch on the front panel is engaged. Check to be sure the AC plug is connected. Check
the fuse.
The Nova unit turns on but there is no sound
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.
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
Nova.
You intermittently lose your signal on the USB input
The first thing to try is rebooting the music server
program ( iTunes, Foobar, WMP, etc) and see if that works.
Then try turning the Nova off, then re-boot your computer.
Then turn the Nova 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 Nova, 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
Nova to remain locked on the USB signal at all times, but
sometimes you can still get a signal dropout.
This can require some trial and error diagnostics.
If you have music files stored on a laptop computer, hook it
up to the Nova and a pair of speakers using battery power.
If it works properly with no noise then your computer in your
office is introducing a ground loop in to the system. This
is not uncommon; but the Nova has transformer coupled
digital inputs to minimize this problem. If problems persist,
please feel free to contact Signal Path.
You pick up hum and noise through your Nova in your
office system
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 Signal Path 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 Nova
Your iPod offers custom equalizations for headphone
use that aren’t necessary with the Nova and a good 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 equalization, then
start at “flat” and make your settings from that point.
