CONNECTING THE MPS-5 TO A WINDOWS BASED PC or APPLE MAC
The MPS-5 provides 2 different ways for you to connect to a computer:
1. Via its internal USB connector on the back panel. This connection is limited to 16bits and 44.1 /
48kHz.
2. Via the USB-X interface. This connection supports PCM resolutions of up to 24/384kHz and DSD up
to 5.6448MHz.
1. CONNECTING THE MPS-5 TO A PC VIA ITS INTERNAL USB INTERFACE
Again, the MPS-5 is equipped with an internal USB port that only supports PCM in 16bits and 44.1/48kHz. In
order to guarantee the best sonic performance of the MPS-5 when playing from other sources connected to
other inputs or from its internal transport the USB port is disabled. This makes it necessary that when a PC is
booted the USB (PC) input is selected on the MPS-5 BEFORE connecting the USB cable from the PC. This
allows the operating system on the PC to identify the MPS-5 and configure its audio port. Once the
connection has been established and the PC is not turned off the input selection on the MPS-5 can be
changed freely without the need to disconnect and reconnect the USB cable. However, when the PC is power
cycled the enumeration is lost and the above described procedure is necessary to gain it back.
The following operating systems are supported without any additional driver installation: Microsoft Windows
XP or later (English and Japanese editions), Apple Mac X 10.0 or later (English and Japanese editions).

MPS-5 User Manual

2. CONNECTING THE MPS-5 TO A PC VIA THE USB-X INTERFACE
Supported PCM audio resolutions: all sample rates up to 384kHz and word lengths up to 24 bits.
Supported DSD audio resolutions: 2.8224MHz (as on SA-CD) and 5.6448MHz.
Connection protocol and method: USB 2.0 / Audio class 2.0 compliant, asynchronous mode where MPS-
5 generates high precision clock master and computer is clock slaved.
PC requirements: Windows 7 or later
ASIO compatible player software such as JRiver, Foobar,
MediaMonkey etc.
Internet connection for downloading software from
www.playbackdesigns.com.
Mac requirements: OS X (10.6.6 or later)
iTunes with or without plug-in to automate sample rate switching.
Internet connection for downloading software from
www.playbackdesigns.com.
In order for your computer to communicate with the MPS-5 and to exchange audio data custom driver
software needs to be installed before you can connect it to the MPS-5. If your computer is a Mac running OSX
10.6.6 or later you don’t need any driver software as OSX already supports all PCM formats up to 384kHz
sample rate. DSD file playback is supported via the DoP standard using PCM frames which is also supported
by OSX without any additional driver. A driver has to be installed on all Windows based PCs for any kind of
audio playback via the MPS-5.
IMPORTANT NOTE FOR PC USERS:
The Windows operating system is by design not a real-time system. It is designed to allow certain processes
to take time away from real-time processes such as playing audio. This can result in audible dropouts,
sometimes very short, but sometimes also quite long. Some PCs are pre-configured with drivers and
processes by the manufacturer that cause such dropouts, and others are user-installed with additional
software that do not allow flawless real-time playback of audio. Fortunately, there is a free utility software that
allows you to test your PC for real-time capability:
1. Go to http://www.resplendence.com/latencymon and download the utility program LatencyMon.
There is also a good description of the program and some more technical background on the same
website.
2. Run LatencyMon, leave it running for 10-15 minutes and the software will tell you if you PC is suitable
for playing audio without dropouts.
If you are considering purchasing a new PC, this utility program is small enough and doesn’t require any
installation which allows you to load it onto a flash stick and test it on the PC you are thinking about buying.
Most computer stores will allow this test.
Preparing your MPS-5 for the connection with the USB-X interface
1. Before connecting the USB-X interface to anything check in the Setup Menu (explained elsewhere in
this manual) that the option "PLINK INPUT" is set to USB-X. You should never attempt any changes
in the menu with the USB-X interface connected.
2. Connect the optical cables as outlined in the drawing below. For this you have to remove the
protective caps on all cable ends as well as on the connectors on the rear panel of the MPS-5. If the
optical cables provided with the MPS-5 are not long enough you can easily replace them with much
longer ones. The specifications are ST DUPLEX to ST DUPLEX 62.5/125 multimode fiber optical
cable. They are usually available in computer stores.
3. Turn on power on the MPS-5 and select PLINK input from your remote. Do not connect the USB
cable from the computer yet, until the driver software for your computer is properly installed, if
required.

MPS-5 User Manual

Driver software installation and first time connection:
1. Turn on your computer.
2. Windows PC users only: Launch your favorite internet browser and navigate to
www.playbackdesigns.com. Use “USBAudio” for password to enter the software download section.
Download the latest driver:
akdesigndrv.zip for PC. Unzip it to the desktop.
No driver software is required for the Mac platform.
3. Windows PC users only: Double click on:
akdesigndrv.exe (PC)
and follow the instructions on your screen. This will install the driver necessary to communicate with
the Playback Designs products via USB.
4. Once your computer is properly configured, power on the MPS-5 and connect the USB cable that was
included with the MPS-5 between USB-X and your computer. Since the USB-X interface is powered
by your computer, but receives the clock signal from the MPS-5 you must always power the MPS-5
first before connecting the USB cable. As soon as the MPS-5 is powered off the USB connection
looses its clock and you will have to unplug and re-plug the USB cable from your computer.
5. Select PLINK input from the remote control if not already done before.

MPS-5 User Manual

6. The computer will take a moment to enumerate the MPS-5 on its USB bus and notify you when it is
installed successfully. Do not attempt to play anything before the computer tells you that the device is
ready to use. You can check successful driver installation and connection:
On the PC in the device manager, where the driver will
show up as AKDesign USB Audio under the Sound,
Video and Game Controllers tab. It will not be listed in
the Sound Control panel.
on the Mac in the Sound Control panel,
where the USB-X should be listed as an
audio output device.
7. For PC users only: Configure your player software to send audio data to the ASIO interface.
Depending on your player software this may be identified as “AKDesign USB ASIO” or simply as
“ASIO”. Some players may need a plug-in for ASIO compatible playback.
8. For Mac users only: launch iTunes.
9. For best performance and bit perfect reproduction make sure to set all volume controls in the
computer playback software, Windows / OSX control panel to exactly 0db (wide open), turn off all
operating systems sounds, effects or equalizer that might be running in your playback software or
Windows / OSX. Control the volume only with your analog pre-amp.
10. Your system is now ready for high resolution playback.
Re-connection after system has been previously configured:
1. Before powering on the MPS-5 connect the USB-X interface as outlined with the drawing on the
previous page.
2. Power on both computer and MPS-5. Select PLINK input on MPS-5.
3. Connect USB cable.
4. Enumeration should be quick on Windows and about 10 seconds with Mac and may not indicate
anything except with failure. You may hear the relays clicking inside the MPS-5 as the computer sets
the sample rate.

MPS-5 User Manual

5. For best performance and bit perfect reproduction make sure to set all volume controls in the
computer playback software, Windows / OSX control panel to exactly 0db (wide open), turn off all
operating systems sounds, effects or equalizer that might be running in your playback software or
Windows / OSX. Control the volume only with your analog pre-amp.
6. Your system is now ready for high resolution playback.
During playback with PC
When changing songs from within your computer player software the USB protocol automatically
communicates all necessary sample rate changes to the MPS-5. The front panel of the MPS-5 always
indicates the true sample rate during file playback. This system will never perform any sample rate conversion
or any signal processing that could adversely affect the sonic performance, but rather use the exact bits from
your file and convert them directly to analog.
During playback with Mac
The native OSX operating system and iTunes do not
understand the needs of audiophile consumers and insist on
sample rate conversion. When connecting the MPS-5 OSX will
automatically select the highest possible sample rate (384kHz)
and convert all your songs to this rate before playing them out
through USB. This will result in degraded performance. You can
manually select the sample rate in the Audio/MIDI Setup utility
to correspond with the native sample rate of the song (as shown
in picture), but this can be a tedious process if your library
contains songs with more than 1 sample rate. Alternatively, 3rd
party plug-ins for iTunes exist that automate this process and
always select the correct sample rate for bit perfect playback.
Check our website www.playbackdesigns.com for an updated list of supported plug-ins.
Playback of DSD files
The driver software and MPS-5 hardware are designed to support playback of DSD files at 2 sample rates:
the standard 2.8224MHz as used on all SA-CDs and the double rate 5.6448MHz as supported by some
professional recording equipment. You will need a playback software running on your computer that can read
DSD files and play them to the USB driver. On the Mac platform you will have to use a playback software or
iTunes plug-in that supports the DoP standard for playing DSD files. Check our website
www.playbackdesigns.com for an updated list of playback software available.
Testing your system for bit perfect reproduction
Windows / OSX and your player software offer multiple places for volume control, effects processing,
dithering, equalization or sample rate conversion. Generally, these algorithms affect the sonic performance in
a negative way, especially in low volume listening levels. It is therefore recommended that all volume controls
on your computer are set to exactly 0db (wide open) and all operating system souns, effects, equalizers and
other algorithms are turned off. You should only control volume with your analog pre-amp. In order to test
your system to make sure that no hidden control or algorithm on your computer may impact your sonic
performance you can play a special test file:
1. Launch your favorite internet browser and navigate to www.playbackdesigns.com. Use
“USBAudio” as password to enter the software download section. Download the test file
“TestPat352.wav”.
2. The test file contains non audible audio, but it is still a good idea to mute your pre-amp.
3. Launch your playback software and play the test file while the MPS-5 is connected via USB and its
PLINK input is selected.
4. If all the controls on your computer are set correctly then the front panel on the MPS-5 will indicate
this by displaying ”BIT PERF” for 5 seconds at the end of the playback. If it doesn’t show this then at
least 1 control on your computer is impacting the performance of your system.

MPS-5 User Manual

General notes
1. For best performance and bit perfect reproduction make sure to set all volume controls in the
playback software, control panel to exactly 0db (wide open), turn off all operating system sounds,
effects or equalizer that might be running in your playback software or Windows / OSX. Control the
volume only with your analog pre-amp.
2. While the MPS-5 has no problem supporting playback via USB while it is switched to a different input
(i.e. disc playback, AES or Coax input) it is a good idea to stop playback on your computer before
selecting another input. The clock management in the MPS-5 may not provide the correct frequency
to the USB port if it is not selected. The computer software may have a problem with that and may
malfunction. So when not listening to the USB input, stop playback on your computer.
When things do not seem to work
The MPS-5 is a hardware device with very little software inside and if it doesn’t show any signs of
malfunctioning in other playback modes, it is relatively safe to assume that the problem is either with the USB
link or the computer. Generally, you should look for any signs of trouble on your computer first, and don’t
assume that because your computer may work with someone else’s USB DAC, but not with the MPS-5, that
the problem is with the MPS-5. The MPS-5 uses different software inside your computer.
Here are a few suggestions for what to do:
1. The USB-X interface is powered by the computer via the USB cable, but the clock signal is coming
from the MPS-5. So every time you turn off the MPS-5 you will have to unplug the USB cable from the
computer and plug it back in once the MPS-5 is powered up again.
2. Make sure that the driver is properly installed (PC only). See step 6 under driver installation above for
instructions for how to check successful installation and connection.
3. Make sure the USB-X is properly connected to the MPS-5 with the included optical cable. Only use
the cable that was shipped with the USB-X. If the front panel indicates “NO LOCK” when the PLINK
input is selected then that points to a broken connection with the USB-X.
4. Make sure you use the USB cable that was shipped with the MPS-5. Other USB cables can be used,
but they need to be USB2.0 compatible.
5. Disconnect the USB cable and restart your computer.
6. Connect the USB cable while the PLINK input is
selected on the MPS-5. On Mac computers it can
take up to 10 seconds to enumerate.
7. On Mac computers it can happen that after successful
enumeration OSX selects the internal audio output
instead of the MPS-5. This can easily be corrected
manually in the sound control panel in System
Preferences as shown in this screen shot.
8. If at this point your PC computer still does not play through the MPS-5 and the driver or USB-X
cannot be identified in the Device Manager (PC) then disconnect the USB cable and try re-installing
the driver following exactly above instructions.
9. If you are a PC user and are able to play audio, but you hear occasional dropouts, please see
IMPORTANT NOTE FOR PC USERS above. You should definitely run LatencyMon.

SETUP MENU
The MPS-5 has several options that can be displayed and set via remote control. By pressing and holding the
CLR button the setup menu is displayed on the front panel. After no further button has been pressed for 5
seconds the display goes automatically back to normal operation. After entering the setup menu the CLR
button can be pressed shortly to advance to the next menu item. Each programmable menu item may be
toggled between 2 settings by pressing the play button.
IMPORTANT: Do not attempt to change any settings while the MPS-5 is connected to any PLINK or USB-X
devices. Always disconnect any optical cables.
The following options are available in sequence:
1. Serial number. This option is not user programmable.
2. Firmware version. This option is not user programmable.
3. Center Mix: Used for multi channel playback and only programmable for the MPS-5.
4. Optical Output Format: the optical data output supports PLINK or SONOMA formats. PLINK is a
proprietary format used to link to other Playback Designs products for multi channel or multi room
setups. SONOMA is used to connect to professional recording equipment. This function is only
programmable for the MPS-5.
5. Optical All Channels: when using PLINK output format set this off for multi channel configuration or on
for multi room configuration. In multi channel configuration only those channels are sent out via
PLINK that are necessary for the next following DAC in the chain. In multi room configuration all
channels are sent out via PLINK output, so that the same audio program can be heard in multiple
rooms. This function is only programmable for the MPS-5.
6. PLINK Input format: The MPS-5 needs to know if the device you are connecting to its PLINK input is
the optical USB-X interface (USB-XII) or any other device that supports the PLINK format.
7. IR Locked / Unlocked: this option is only programmable for the MPD-5 and allows disabling all remote
control commands when the MPD-5 is part of a multi channel setup.

MULTI CHANNEL CONFIGURATIONS
The MPS-5 can be configured for various different applications in multi channel setups and SACD MCH
playback. As the MPS-5 is equipped with 2 internal analog outputs it can be combined with the Playback
Designs companion stereo D/A converter (MPD-5) for external analog processing of the additional channel
data from SACD MCH discs. The possible configurations are:
1. Stereo only playback from SACD MCH: the player will only read the LF and RF channels from SACD
MCH discs. This is the factory default configuration. The user can switch between stereo and multi
channel layers on SACD’s, but the player will only read 2 channels from the selected layer and only
send out 2 channels via the PLink output.
2. 4-channel playback from SACD: the player reads all available channels from SACD MCH discs,
mixes the center channel into left and right front channels for output directly from its internal analog
outputs. The left and right surround channels are sent out digitally via the optical PLink (DATA) for
analog conversion by the Playback Designs companion product MPD-5. All stereo discs are played
normally with analog outputs from the player and muted outputs via the PLink output.
3. 6-channel playback: the player reads all available channels from SACD MCH discs. While only 2
channels are available from its analog outputs (LF and RF), it sends out digital audio data for the
other 4 channels via the PLink output.
The various configurations and corresponding parameters can be set via a setup menu on the front panel:
1. In order to enable multi channel output the player needs to be set into multi channel mode (factory
default setting is stereo) by first pressing and holding the STOP key and then pressing the NEXT key
on the front panel. Each time this key combination is pressed the modes are toggled between stereo
and multi channel. In stereo mode the player will automatically select the stereo program each time a
SACD is put in. Likewise in multi channel mode the player will automatically select the multi channel
program each time a SACD is put in, provided it contains a multi channel layer.
2. By pressing and holding the CLR button on the remote a setup menu is entered that allows the user
to program several features. There are 3 menu items that pertain to the multi channel configuration.
The programming can be toggled by pressing the PLAY button on the remote. After 5 seconds of the
last button press from the user the setup menu is exited automatically and the player can be used
normally again.

EXTERNAL CLOCK
A unique feature of the MPS-5 is its elaborate and sophisticated clock generator which does not require to be
locked to an external source. It completely shields any incoming digital audio stream from its sensitive internal
clock circuitry through various stages of buffering with unique control algorithms. This removes any incoming
jitter from external sources so well that no complicated setup with master – slave clocking configurations are
needed, as is often the case with other equipment. In fact, the MPS-5 performs equally well with jittery
sources as with higher quality ones. For this reason the MPS-5 does not require an external clock nor does it
require to be set up as a clock master.
BREAKING IN THE MPS-5
Breaking in the Playback Designs MPS-5 is time consuming but well worth the effort. It would be a mistake to
pre-judge the player based on what you might hear at first listen. This is what you can expect to hear at
different intervals during break-in:
1. Out of the box: The player will have good clarity, but the highs can be recessed. Bass might appear to
be a bit muddy and lacking punch. Soundstage might sound closed in.
2. 50 - 150 Hours: The sound will open up a little bit, but can still sound a bit brittle.
3. 150 - 350 Hours: Midrange will start smoothing out and clarity will increase, but highs might continue
to remain recessed. At this point, there probably will not be much change in the bass. You will
probably wonder how the Playback Designs converter will ever sound like others have described, but
we assure you that you will start to hear substantial changes within another week of play.
4. 350 - 500 Hours: The magic will be starting. Highs will be open and airy. Midrange will appear much
more full bodied and natural. Soundstage will be huge and the image presentation will start appearing
very holographic. Bass will be incredibly deep and tight with texture and detail galore.
5. Over 500 Hours: The player will continue to change subtly over the upcoming month of usage, but
you should be recognizing a very life-like and natural sound.
During break-in when you do not listen to music it is best to feed an external digital audio signal into any of
the digital inputs of the MPS-5, rather than loading a disc and setting the drive into REPEAT mode.

CHANGING THE FUSE ON THE MPS-5
Inside the power connector on the rear panel of the MPS-5 is a fuse that protects the player from dangerous
power surges. If the player fails to power up or no light on the front panel is lit then proceed as follows to
change the fuse:
1. Locate fuse compartment on power connector on
rear panel.
2. Use a small screw driver to pry open the fuse
holder.

3. The fuse holder contains 2 fuses. The top one is a
spare and can replace the blown one at the bottom.
4. Replace fuse holder into power connector by
making sure that good fuse is at bottom.
Replacement fuses should be rated: 1.6A / 250V

Appendix A: Serial Remote Control (RS-232)
The MPS-5 can be remote controlled via a 9-pin RS-232 link. When connecting to a PC the required cable
should be non-crossed and the link parameters should be set to:
19,200 baud
8 bits
1 stop bit
no flow control
no parity bit
Commands to the MPS-5:
All commands sent to the MPS-5 consist of 3 ASCII characters followed by a <CR>. Repeating a <CR> will
repeat the last command sent. Received commands are not stored in a stack and, therefore, need to be sent
in intervals of at least 100ms to allow enough time for the MPS-5 to execute a command before receiving the
next one.
