One man’s quest for music
Sprout is my vision of a simple, elegant means of playing music at
home. I created it for those of us who want quality sound without the
hassles that sometimes come with it.
I’ve admired the design principles of Dieter Rams, who taught us to
design as little as possible. I fashioned Sprout to honor that ideal. I
wanted Sprout to be a device you and I connect with. Rather than
a display screen and endless menus, Sprout’s user interface is a
direct hand-to-Sprout connection through just two knobs. These
allow intuitive, direct control of Sprout, and provide feedback to the user
through a positive click and immediate response to changes in volume.
Sprout’s ease of use should make it appealing and accessible to those
who would nd most audio gear intimidating; it should also appeal to
those who have “been there, done that” and seek a better, simpler way
to play music in their home.
Sprout is for those of us who care about their home, their music, and
their enjoyment of music in the home.
Sprout is personal and I am honored you connected with it.
Thank you.

Connect the inputs rst
Sprout has four rear panel inputs you can connect your sources to:
two digital, one analog and one phono for your vinyl. It can connect
wirelessly via Bluetooth
Digital sources
Digital technology is the force behind our land-lines, smart phones,
computers, and the internet itself. It’s also a great way to hang on to
your music. We use digital formats, (like FLAC, ALAC ,WAV, and MP3s)
to store our favorite tunes. Sprout can play these formats using your
computer or smart phone.
Sprout can connect to three digital devices, two from the rear panel
connections and one wirelessly via Bluetooth from your phone,
computer or tablet.
The two digital inputs available on the rear panel are USB and COAX.
USB Connection. USB connects Sprout to your computer. Once
connected, Sprout will become the audio output of your computer,
playing from programs like iTunes or Windows Media Player. Using a

® Owner’s Reference Sprout

standard USB cable, connect Sprout to your computer’s USB port.
If you are running a Mac computer, the driver for Sprout is built in. If
you are instead on a Windows computer, you will need to download
and install the USB driver onto your computer. To download the USB
driver go to PS Audio’s website: www.psaudio.com. Go to Support-
>Downloads and download the USB driver.
It will be necessary to unzip the le and install it on your computer. This
will connect your Windows computer to Sprout. You must then select
“PS Audio USB 2.0 Audio Out” (on a Mac) as your output device or, “PS
Audio Sprout” on Windows.
COAX Connection. If you have a CD player, transport, Apple TV 1,
Sonos or any digital audio device with a coaxial digital output, use a
standard RCA interconnect cable to connect the digital output of your
device to Sprout’s COAXIAL input as shown in the back panel diagram.
Wireless Bluetooth Connection. Sprout’s wireless Bluetooth antenna
is built into the back panel as shown on the rear panel diagram. It is
unnecessary to connect anything for this to operate. See operating
instructions to understand its use.
Vinyl Turntable Connection. Do you listen to records? We do too. To
use Sprout for vinyl, the phono inputs must be connected only to a
turntable. Connecting a standard analog source that is not a turntable
into these inputs is going to sound pretty strange. Some turntables are
already amplied, do not plug this into Sprout. Sprout will connect to a
standard Moving Magnet cartridge turntable without any problems.
Plug the left and right cables from your turntable into Sprout’s input
labeled Vinyl. The red vinyl input is right, the white is left.
Sprout plays both grounded and ungrounded turntables. Most
turntables have a ground wire, in addition to the RCA output cables.
This ground wire lowers the chance for hum. Connect the turntable

ground wire to the rear panel ground binding post located directly
above the analog in and out connections.
Analog inputs and outputs. Sweet! Facing Sprout’s rear panel there
are two small connectors labeled Analog, Out, In.
Analog Output. The connector labeled “Out” located above “Analog”
on the rear panel is a buered stereo line output. This is the full audio
output directly from Sprout’s volume control. Whatever you are listening
to on Sprout will be available on this output. Connect this output to a
separate power amplier or subwoofer.
Connecting a subwoofer. Many small speaker pairs benet from the
addition of a subwoofer to augment the low bass of the little speakers,
giving a much richer, full range musical sound. Use the Analog Output
of Sprout to feed a subwoofer. Most subwoofers have RCA input
connections. Sprout’s output is a smaller 3.5mm connector. Use a
3.5mm to RCA adapter to connect the two devices.
Analog Input. The connector labeled “In” located above “Analog” on
the rear panel is a stereo line input. Use this input to connect the output
of a mobile device, television, tape deck or any source with an analog
output. The connector is a 3.5mm stereo jack. It may be necessary to
use a 3.5mm to RCA adapter to connect some devices to Sprout.
Connecting a television or cable box. Sprout can easily be connected
to a television or cable TV box through its analog inputs. Most modern
TVs and cable set top boxes have an analog (line) audio output
available. Many use Sprout’s 3.5mm connector, while others use the
larger RCA connections. It may be necessary to use a 3.5mm to RCA
adapter if the outputs and input connectors don’t line up.
It is also possible to connect a television or cable box digital output to
Sprout. Using the analog inputs is preferred because this arrangement
uses the television volume control with the device’s remote control.

Speaker Connections
Sprout’s power amplier provides enough wattage to power just
about any loudspeaker pair. However, we recommend only one pair of
loudspeakers be connected at a time.
Loudspeaker Connections. It is important to make sure you match
colors and channels from Sprout to your loudspeakers correctly. Red
should go to red, black to black. Failure to do so will produce some
funky sounds, lack of bass and won’t give you what Sprout’s capable of.
Facing Sprout’s rear panel, the right loudspeaker pair is on the left, the
left loudspeaker pair is on the right. This might seem backwards but
viewed from the front panel, it is correct.
Connect red (+) of the right speaker to Sprout’s red (+) right speaker
output. Connect the black (-) of the right speaker to Sprout’s (-) right
speaker output directly below it. Follow the same convention for the left.
Make sure none of the wires touch each other or Sprout will not play.

Connect the AC power
Using the supplied AC power cable or an aftermarket cable you might
have, connect Sprout to your home’s AC wall socket for power.
Sprout may only be connected to your country’s voltage. Sprout
will not operate in a country it was not purchased in. Serious damage
to Sprout will occur if you attempt to do otherwise. If you are in the
United States, Canada, Mexico, Japan or any country with 120 volts AC
as standard, Sprout will only work in your country. Do not attempt to use
a 120 volt Sprout in a 230 volt country like those in Europe, UK, Asia,
Australia or Africa. Serious damage will occur.
Plug Sprout into the proper AC receptacle. If you are outside North
America and your home’s receptacles do not match Sprout’s AC cord,
use the supplied adapters to connect Sprout to your home’s AC power.
Turn Sprout On. Using the main AC power switch, located on the rear
panel of Sprout just above the incoming AC receptacle, turn Sprout on
and start enjoying some music!

Using Sprout
Now that your sources are connected, the AC plug is feeding power and
the rear panel AC power switch is on, let’s play some music.
Playing music on Sprout couldn’t be simpler. Choose what you wish to
listen to using the Input Selector and turn the volume knob up or down
to adjust the loudness of the music. If you have a pair of loudspeakers
connected to Sprouts output connectors, music should play through
your speakers. If you are listening through headphones plugged into the
front panel, music should play through the headphones.
Input Selector. There are four input choices on the Input Selector: Vinyl,
Analog, Digital, Bluetooth. Select which of these you wish to listen to.
Vinyl. If you have a turntable (record player) connected to Sprout’s rear
panel inputs labeled “Vinyl” you should get music playing when the
Input Selector is in this position with the record on. Sprout accepts a
moving magnet (normal) cartridge. The sound should be great. If the
sound is boomy or distorted check to make sure you do not have a
turntable with a built in amplier. Sprout is designed to

® Owner’s Reference Sprout

accept the direct output of your turntable’s phono cartridge.
Analog. Select this input if you have a phone, television, Sonos or
other device with an analog output connected to Sprout’s rear panel
connector labeled “Analog In”.
Digital. Select this input if you have either of the two digital inputs
connected: USB or COAX. We recommend you plug only one of these
two digital inputs in at a time. Should you have both USB and COAX
plugged in at the same time, USB will take precedence over COAX when
the computer it is connected to is on.
The digital inputs can accept sample rates and bit depths up to
192kHz/24 bits.
If you are using USB connected to a computer, it may be necessary for
that computer to have a PS Audio driver installed to connect Sprout. If
you have a Mac it is already installed. If you
are connecting to a Windows computer, you
must install the PS Audio Driver rst. See the
previous input connection instructions in this
manual for details.
Bluetooth. Select this input if you have
connected a mobile device or computer
enabled with Bluetooth to Sprout. Bluetooth
is a wireless method of connecting devices
together. To connect to Sprout from a
Bluetooth enabled device, such as an iPhone
or an Android, go to the mobile devices
settings menu and nd Bluetooth. Make sure
the mobile device’s Bluetooth is active and on.

4826 Sterling Drive, Boulder, CO 80301 . PH: 720.406.8946 . www.psaudio.com

With Bluetooth active on your
mobile device, go to the discovery
screen for Buletooth devices in the
Setting menu (see your phone’s
instructions). Look for “Sprout” and
connect to it. Sprout will remember
your phone and automatically
connect with up to two devices
once it has learned your mobile
device’s identity.
Once your mobile device is
connected to Sprout, anything you
play on your mobile device will now play on Sprout.
To control the volume when connected via Bluetooth there are two
methods: Sprout’s main volume control and the mobile device’s
volume control. Typically you would turn Sprout’s volume control to
a comfortable listening level rst, perhaps the 12 o’clock position on
the volume knob. Then use the mobile device’s volume control for ne
adjustments.
Headphones. Plugging a pair of headphones into Sprout’s front
panel headphone connector automatically disconnects both the
loudspeaker outputs as well as the Analog outputs. In this way, Sprout
provides a truly personal listening experience for the headphone user.
Disconnecting the headphones restores the loudspeaker and Analog
Outputs.

Headphone jacks come in two dierent sizes
• 3.5mm (called three-and-a-half mil) which you nd on most
SmartPhones and MP3 players. They look like this:
• ¼” (called quarter-inch) which you’ll nd in a lot of specialty
headphones. They are quite a bit bigger, and look like this:
You might notice that Sprout has an input for a quarter-inch jack
You may also notice that Sprout comes with an adaptor.
So you can plug your headphones in like this:

Sprout’s near-zero output impedance headphone amplier has been

Troubleshooting
Sprout is easy to setup and use. From time to time a few problems
might be encountered and we trust this quick troubleshooting guide
may assist you. Should you have any problems we don’t resolve in this
section, we’re always here to help. Feel free to contact PS Audio or your
dealer for assistance, should it be needed.
Can’t get anything to work. Sprout has a rear panel power switch just
above where the AC power cable plugs in. Make sure this switch is in
the “ON” position.
Speakers keep cutting out. Sprout is well protected against accidental
misuse. If Sprout plays then cuts out there’s likely one of two problems:
you have a speaker wire touching or you’re playing it too loud. The rst
thing to check is your speaker cables. Look closely on both the speaker
and Sprout ends of the cable. Make sure the bare wire of the speaker
cable is not touching Sprout’s chassis or another speaker cable.
If the connections are okay and Sprout cuts out when you’re playing it
loudly, it may be your speakers are too power hungry or you’re asking
too much of Sprout. Turn it down to see if the problem goes away.
Sprout plays loud and nice with just about any loudspeaker, but it isn’t
going to go beyond its capabilities.
Can’t get the COAX input to play. Sprout really wants only one or
the other digital inputs connected at the same time. You can connect
both the COAX and USB inputs up simultaneously, but USB will always
override COAX. Either turn the computer o or disconnect the USB
cable to allow the COAX output from a CD player to work when in the
Digital mode.
Can’t get my TV to play nice with Sprout. You’ll want to make sure
the “Line Out” on the back of your television is connected to Sprout’s
Analog Inputs. Then, go to the TV’s settings menu and select Audio

® Owner’s Reference Sprout
4826 Sterling Drive, Boulder, CO 80301 . PH: 720.406.8946 . www.psaudio.com

Settings or Speaker Settings. Change it to the Audio System setting
which disables the television’s internal speakers and sends the sound to
Sprout.
The goal here is to disable the TV Speakers and use the Audio System.
We don’t want music or programming to come out of the television’s
speakers. We only want it going into Sprout.
Some TV’s have xed analog outputs. It’s usually written right on the
back of the TV next to the connectors. When you are connected, if the
remote control doesn’t change the volume through Sprout automatically,
bummer, you will need to change the volume on Sprout’s front panel by
hand. Cool?
However, your TV may have variable analog outputs. This means when
you use the TV’s remote to control the volume, it changes the amplitude
of the line-level signal. If your TV has variable line-level outputs, rock
and roll. You can use the TV’s remote to control the volume AND you
can use Sprout to control the volume. That’s called secondary volume
and master volume, respectively.
