DAC-2v2 Series Design Features
The new DAC-2v2 series (DAC-2v2 and DAC-2v2SE) represents our latest step forward in DAC design and
innovation. These new DACs offer some of the latest technology available today and bring new life to digital music.
The new DAC-2v2 features the ESS Sabre 9028PRO DAC chip, while the DAC-2v2SE is equipped with the flagship
ESS Sabre 9038PRO chip. The ESS Sabre Pro DAC is the world’s highest performance 32-bit audio DAC solution. In
our implementation, we utilize the 8ch chip in quad-differential mode meaning that there are actually four differential
D-A conversion circuits for each channel in parallel. This helps achieve a spectacular S/N ratio and output drive
capability. The I²S DSD format offers a jitter-free solution to transmitting digital data from our cutting-edge USB
interface to the Sabre chip. Newly implemented technology and hardware now takes full advantage of this
remarkable feature. The upgraded interface instantly detects the native DSD data and routes the signal to the
appropriate internal processors resulting in unparalleled sonic performance.
Another design feature is the galvanically isolated I²S USB interface which prevents computer noise from interfering
with the quality of the audio signal. Setup with your source via USB is driverless for Linux and Mac, while Windows
users will require a quick driver install to begin playing your favorite tracks.
The DAC-2v2 series can process signals up to 24/200 kHz via the coax digital inputs. Toslink inputs are tested to
function up to 192 kHz sample rate, although due to limitations inherent in toslink transmission, a maximum of 174.6
kHz has proven to be more reliable. Both the USB input and I²S input will process signals up to 32 bits in length and
sample rates of up to 384 kHz PCM and DSD 256.
Each of the coax inputs are transformer coupled to isolate the source while maintaining proper loading. To ensure
that the lowest input signal level will satisfy the digital conversion engine, the signals also pass through TTL buffers to
maintain consistent signal integrity. To simplify input selection, the ESS chip is also used as the receiver chip and
performs all the signal selection and routing. Automatic signal up-sampling is done internally to keep output filtering
to a minimum, and is a crucial part of the jitter elimination. To ensure source immunity, the time domain jitter
elimination is executed as the signal enters the DAC chip by re-clocking to the desired rate selected by the ESS chip.
With an oversized toroidal transformer, more than 115,000uF of capacitance, 3 stages of filtering and 13 regulation
points, the power-supply in the DAC-2v2 series is incredibly robust. The analog output stages are powered by a
separate power-supply to ensure isolation from the digital front-end. House-keeping voltages also use separate
supplies to guarantee minimal supply contamination. The digital board is supplied with 7 out of the 13 dedicated
regulators to ensure tight tolerances and consistent power delivery.

Another key component adding to the incredible sound quality of the DAC-2v2 series DACs is the proprietary
discrete output stages. Instead of choosing the simple path like many others, we took the “dirt road” and it paid off in
a big way in the form of transparency and naturalness of sound. The grain-free soundstage reproduction is the
product of our discrete dual-differential FET input amplifier stage which uses all Dale RN55d resistors for precise
control. Because of the dual differential circuits, the completely balanced signal offers balanced and unbalanced
outputs which both take advantage of common-mode rejection.
The New Reference: DAC-2v2SE
The DAC-2v2SE starts with the already incredible DAC-2v2 and substantially improves upon its design and sonics.
Key components throughout the entire audio circuit are upgraded—including utilizing the reference-level ESS Sabre
9038PRO chip—culminating in a reference-level DAC that rewards the listener with the most engaging and life-like
sonic experience possible.
Upgrades bestowed on the all-important power circuit include low-loss ultra fast Schottky diodes, premium
inductors, upgraded fuse, a series of custom low ESR capacitors and newly designed discrete regulators, which are
more than 100 times quieter and faster than stock.
The analog signal is significantly improved with custom-made naked Vishay Z-Foil resistors in 20 locations.
Compared to the stock Dale resistors which offer 1% tolerance and +/-100ppm/°C temperature coefficient, the new
resistors are 0.1% and +/-0.5ppm/°C respectively.
For the most accurately timed digital signal, we replace the standard clock with a Femto-grade clock—one of the best
available. The new clock optimizes audio quality by lowering phase jitter by over 80% as well as greatly reducing
phase noise in the digital circuit. This is crucial in obtaining the highest fidelity, distortion-free output.
Finally, we complete the 2v2SE package with a quieter, green OLED display, further distinguishing this model. The
result of such extensive labor and attention to detail is that the DAC-2v2SE is simply one of the best DACs on the
market today.

Front Panel Operation
The front panel of the DAC-2v2 series is a model of elegance, simplicity and efficiency. An LED display and three
simple buttons give the user a wealth of control and configuration options.
1. LED display
The two-line LED display will show input and file information on the top line and volume information on the
bottom line (either the volume level or the word “FIXED”). The active line is indicated with a “—” on each
side. When a sample rate is displayed, the DAC is receiving and locked onto that rate. “< ? >” indicates no or
lost signal. When in the Setup Menu, the display will show menu items and settings.
2. Power button
When the rear switch is on, the Power button turns the DAC on or puts it in low-power standby mode.
When the DAC is powered on, tapping the Power button will toggle between top and bottom lines on the
display. When in the Setup Menu, the Power button is used to select and confirm options. We strongly
recommend putting the DAC in standby mode when not in use. This prolongs the life of DAC and display.
3. Down and Up buttons
Depending on which line is active on the display, use the Down and Up buttons to switch inputs or change
volume level (if set to “VARIABLE” in the Setup Menu). While in the Setup Menu, use the Down and Up
buttons to toggle through menu options

Powering Your DAC
When a power cord is connected to the AC input and the rear switch is turned on, the DAC is ready to be turned on.
Use the Power button on the front to turn the DAC on or put it into a low-power “standby” mode (display will be off).
Leaving the rear switch in the on position will keep power supplied to the DAC. Turning the rear switch off
disconnects all power.
Setup Menu
The extensive Setup Menu gives the user many options to configure your DAC. To enter the Setup Menu, ensure the
DAC is in standby mode (the rear switch is on but the DAC is not powered on with the front Power button).
1. Push and hold the Up and Down buttons and simultaneously push the Power button, then release all three.
The Setup Menu is now shown on the display (you will see the first menu item, “IIR BNDWITH”).
2. Once the menu is activated, you can use the Up and Down buttons to scroll through the menu.
3. When an item is displayed that you wish to adjust, press the Power button quickly (do not press and hold or
the unit may turn off) to enter that item and use the Up or Down arrows to scroll through item options.
When the desired option is displayed, press the Power button quickly again to save the selection and return
to the main menu.
4. When finished, press and hold the Power button while in the main menu. The unit will go back in standby
mode and your changes will be ready for use the next time the DAC is powered on.
Default Reset: Should you wish to reset all menu items to factory default settings, first power the unit off front panel
Power button. Next, push and hold the Up and Down buttons while pressing and holding the Power button. This is
similar to the procedure to enter the Setup Menu, except you will continue to hold all three buttons in for a few
seconds. You will then see “----RESET----” on the display, at which point you can release all buttons. Once the
screen goes blank, the reset has been applied and all settings are restored to their factory configuration.
Setup Menu Tables for DAC-2v2 and 2v2SE are on the following two pages.

Setup Menu Option Details
Bandwidth/IIR Settings
The Bandwidth/IIR Setting more for personal taste and fine-tuning. The default setting is typically the best for most
users, however, feel free to adjust it according to your preference. PCM bandwidth selects the range of which the
DAC will filter the signal. Allowing higher bandwidths may introduce more information, but also more noise. IIR
stands for Infinite Impulse Response. Please note that these settings will likely not offer significant sonic differences
and might not be appreciated until the unit is fully “broken-in”.
Filters
Each filter curve subtly affects sonic signature and allows the user to fine-tune the overall rendition to individual
tastes. Default setting is what we prefer, but feel free to experiment with different options.

S Type setting adjusts the signal
timing alignment based on what you connect. It will be obvious if the this is set improperly (very distorted sound).
Please note, I
2
S is NOT a ‘typical’ A/V HDMI connection and is incompatible with DVD players, game consoles, TVs,
etc. The corresponding source must also be specifically I
2
S equipped.
Remote Control/DC Trigger
Your new DAC is equipped with a DC trigger output and input jack on the back panel. The Trigger input is on the top
and is used for the HT Bypass or Trigger-on feature. In the Setup Menu, you can select the trigger input to be
configured as a HT Bypass or Remote turn-on feature.
●HT (Home Theater) Bypass mode:
When the setting under “TRIG” is Off, then the HT Bypass on trigger input is active. To use the HT Bypass
feature, connect the pre-outs of your home theater receiver or surround sound processor to the HT Bypass
inputs on the DAC (be sure both DAC and receiver are off before doing so). When either the HT input is
selected on the remote control or the trigger input is activated, the HT Bypass inputs will activate and the
display will read “HT BYPASS”. Caution: be aware that the HT Bypass inputs is a line-level signal at full
volume. Be sure that your receiver or processor’s volume is turned down before playing any material.
●HT dim level:
When in the HT Bypass mode, different display dim settings can be set in the Setup Menu. When going back
to normal operation the pre-selected dim level will be restored, regardless of the HT dim level setting.
●Remote Trigger On mode:
When the setting under “TRIG” is On, the remote turn-on with trigger input is active. When the DC trigger
input is applied, the DAC will power up as if you pushed the Power button on the front panel. The last used
input will be selected upon power up. The trigger input signal needs to remain active for the unit to stay on.
Once the trigger falls low, the unit will return to the off state.
●Trigger output:
The lower trigger connector is used for a trigger output to remotely power up power amplifiers when the
DAC is on or in HT mode. Connect one 3.5mm DC trigger cable from the trigger output of your source to the
DAC trigger input to remotely activate the HT bypass or remote turn on feature (one or the other based on
the Setup Menu setting). Connect another 3.5mm cable from the trigger output of the DAC to the trigger
input on your power amps if supplied with one. This will remotely activate your power amps anytime the
DAC in operational even when in HT MODE.
●Remote:
When the setting under “REMOTE” is Off it will disable the remote. This can be beneficial when you are
operating the DAC with another Wyred component such as the STI or STP-SE in order to eliminate
interference between them. A setting of On leaves the remote control active.
Input Level (DAC-2v2) or Volume Level (DAC-2v2SE)
Choose Fixed or Variable for input/volume level. Fixed mode bypasses the internal DAC volume control, while
Variable mode engages it. Fixed mode should be used if you are connecting the DAC to a preamplifier, receiver, etc.
to use that component’s volume control. Choose Variable to use the DAC’s internal volume control for connecting
13

directly to an amplifier. On the DAC-2v2, you can adjust this for each input type. On the DAC-2v2SE, the Volume
setting is global, affecting all inputs.
Minimum/Maximum Volume Level Settings
The Min/Max volume level settings can be set differently for each input type and allow you to tailor and optimize the
DAC’s output to your preamplifier (or amplifier if connecting directly). For many users, the default settings will work
best. However, with so many gain variables inherent in different systems, being able to raise the minimum output
level or lower the maximum one can be an invaluable feature.
The volume table for the DAC is 70 steps in size and offers different size steps depending on the location of the step.
When the minimum level for the corresponding input is set to 5, the maximum level will be 65. Essentially, the Min
level is the amount of steps skipped in the first position. When used, the Min amount is subtracted from the 70
possible steps total.If a system doesn’t have enough gain to utilize the bottom several steps, you can remove them
from the table by raising the Min setting to within the playback range of the system. Similarly, if you find the DAC
output level too high, you can adjust the Max level down to within your personal preferences. See the Output Level
Adjustment table on page 17 for volume level settings and the corresponding output voltages.
Example: With a less efficient system requiring a DAC volume level of 12 to hear anything, setting the Min level of 10
removes steps 1-10 which likely will be desirable. In this instance, the Max volume would then equal 60.The volume
table offers from 3db to 1dB steps as follows (refer to the end of this manual for a chart correlating volume level to
output voltage):
●0 = mute
●Steps 1-9 = 3dB
●Steps 10-24 = 2dB
●Steps 25-70 = 1dB
Discrete Input
Input selection with the standard remote is accomplished by scrolling up or down through all available inputs. While
our remote control does not have the option for direct input selection, many universal remotes can support that
feature. The Discrete Input Setting (on/off) enables or disables the direct input commands that can be received by
the DAC. The database for the Logitech universal remotes has these commands pre-loaded for your convenience.
Jitter Eliminator (DAC-2v2SE only)
This option sets the ‘window’ of digital signal tracking employed by the DAC chip. The lower the setting, the tighter
the window. Signals with higher jitter could be harder to track, which would result in brief signal dropouts. However,
at lower settings, the sonics may improve. If you are experiencing dropouts, try setting this option higher.
Dim Delay (DAC-2v2SE only)
Dim Delay is meant to provide optimum sound, reduce internal heat and preserve the OLED display on your new
DAC by turning off the display after a set period of time. Set the number of seconds the display will stay on until it
goes off. Note, every time you use the remote or front panel to change something, the display will come on and stay
on for the number of seconds this option is set to. If the display is off and you wish to check it, push the Power button
on the front of the DAC or the Dim button on the remote. The display will come on for the number of seconds set for
this option.

Remote Control
The remote control supplied with the DAC-2v2 series offers you full functionality. Also, if you find the need to, you
can always program a universal remote to control the DAC as well (set the Discrete Input in the menu to “On”). For
your convenience we have uploaded the remote commands to the Logitech universal remote database.
Balance and display dim controls are exclusive to the remote control. Distances of up to 20 ft. or so shouldn’t be a
problem for the remote, but further distances might not behave properly. Note: The phase button is disabled and
non-functional.
USB Conguration
The USB interface of the DAC-2v2 is driverless for Mac and Linux, thus the DAC-2v2 series is ‘plug-n-play’ for those
operating systems. For Windows, the included driver disk has standard drivers as well as ASIO® drivers. All users
(Mac, Linux, PC) will need to configure the DAC as the output device for their computer. Please see step 6 below.
Windows Setup
When using the DAC with a Windows machine via USB you MUST install the drivers before connecting the DAC. Do
not connect the DAC with a USB cable until the drivers are completely installed. The included ASIO® drivers are not
required for audio playback but can be beneficial in some configurations. If you do choose to install the ASIO®
drivers, be sure to install them after the standard driver installation is complete. ( ASIO ® is a registered trademark of
Steinberg Media Technologies GmbH.)
1. Insert the included CD into the disk drive of your computer
2. Locate and open folder that shows the contents of the CD
3. Double click the correct Setup32 or Setup64 file to initiate the install.
4. Once the install process has begun, follow the on-screen instructions. The install wizard will prompt you
when the process is complete.
5. Connect the DAC to your computer with a USB cable, power the DAC on, and select the USB input. You may
be prompted by an install wizard that additional installation steps are required. Follow the on-screen
instructions. The install wizard will prompt you when the process is complete.
Selecting the DAC as the Audio Output Device
6. It is now necessary to select the Wyred 4 Sound USB interface as the default output device for your system.
The device name will vary depending on the operating system you are using.
a. MAC OS: 32bit 384kHz DSD Interface
Locate and open the Audio MIDI Setup: Go to Finder > Applications > Utilities > Audio MIDI Setup.
Select the W4S DAC as the default output device and apply the setting.
b. Windows: Digital Output / Wyred 4 Sound USB Driver 1.0.56
Locate the Audio output device (Manage Audio Devices) selection which is found in the control
panel located in the startup menu. You will need to set the default output device to the Wyred 4
Sound interface. This setting will be part of the OS and not the media player.
Please note: Additional output configuration and device selection may be required in your media player.
7. The last step is easy—enjoy your music!

“Break-in” Period
Your new DAC will deliver outstanding performance brand new. However, over the course of playing it for the first
200 hours or so, the DAC will go through a “break-in” period as it reaches its ultimate sonic potential. This is a normal
phenomenon of high-end audio equipment and the before/after differences are readily audible. If you are hearing
bright, tight, light or dimensionally flat characteristics, those are symptoms of a product that is not quite broken in
yet. Patience will reward you! After the break-in period, your unit will be ready to perform as soon as it’s powered
on. If you have any questions on your DAC’s performance, contact your dealer or Wyred 4 Sound directly.

No sound? If you have your input source and speakers connected, and you can’t get music to play, check the
following:
1. Verify that the power cord is plugged in and that the outlet is powered up.
2. Check the front panel and make sure that the display lights up.
3. If the display is on and the DAC is locked onto a signal, increase the volume to a significant level to ensure
the level is high enough for music playback.
4. If you can hear the slight turn on and off noise when the DAC is activated, but there still isn’t any sound,
make sure you are getting a signal to it.
5. Verify that the input is selecting the proper input for what you have connected, and is displaying a sample
rate.
6. If the input is in the proper position and still no sound, then try replacing the interconnects to verify the
connection between the DAC and source.
7. Verify that the interconnects are conducting by replacing them on a different set from a connection that you
know works.
8. Now that you have interconnects that you know work, try connecting the DAC to another source that you
know has worked in the past.
Note: Because the DAC-2v2 is really an 8ch DAC inside, make sure that all sources (where applicable, ie: DVD
players, cable/satellite boxes) are programmed in their Setup Menu to output 2ch PCM or stereo digital signals. In
some cases, the DAC will actually try to decode multichannel formats, but will be unsuccessful because the DAC’s
outputs are tied together internally. If you hear loud switching noises, or no sound at all, this may be why.
Got Hum?
Is there hum or hiss coming out of your speakers? If you put your ear right next to the tweeter of your speaker, you
should barely be able to hear any hiss in normal conditions, depending on amps. If the noise is easily heard at a
distance, try putting your source on mute, or pause. If this eliminates the noise, it’s inherent in the source. If the
noise is still there when the preamplifier is muted, try disconnecting the inputs to the amplifier. If the noise is still
there when the amp inputs are disconnected, and the inputs are shorted with shorting plugs, then your amplifier may
need some servicing. If the noise is not there when the inputs are disconnected, try putting a cheater plug (ground
isolator) on one or all components in order to eliminate a ground loop issue. NOTE: We only recommend using a
ground isolator for troubleshooting purposes, and should be removed after the problem has been found. Having the
ground of any unit disconnected can potentially create a dangerous situation.
If you are still experiencing problems after checking all possibilities and using the resources provided please contact
your dealer or Wyred 4 Sound directly for further assistance.
