Installation: The AC voltage supplied to the unit should match the voltage rating
indicated on the rear panel.
Do not place the converter on the amplifier or any other equipment that
generates heat.
As the converter may become warm during operation, always leave
sufficient space around the converter for ventilation. Always allow
adequate air circulation around the player.
When moving the converter, make sure to turn off the power and
disconnect the power cord.
FRONT PANEL FUNCTIONS
The front panel has no user buttons or switches, just an alphanumeric display. All functions of the MPD-5 are
controlled via the IR remote or the serial RS-232 interface.

CONNECTIONS
Analog outputs: XLR: balanced, 4Vrms @ 1kHz full level, pin 2 Hot
RCA: unbalanced, 2Vrms @ 1kHz full level
BNC: unbalanced, 50Ω, 2Vrms @ 1kHz full level
Digital outputs: XLR: AES/EBU formatted for stereo linear PCM data.
DATA / CLOCK: Only the DATA output is used for the proprietary optical link (PlayLink)
to other Playback Designs equipment, such as the MPS-5 integrated
disc player.
Digital inputs: AES: XLR connector for AES/EBU formatted stereo linear PCM data, up to
24bits and up to 192kHz.
S/PDIF: same as AES, but S/PDIF formatted on RCA connector.
TOSLINK: same as S/PDIF, but on optical connector.
PLAYLINK: This optical proprietary link (PlayLink) is used to connect to other
Playback Designs equipment, such as the MPS-5 integrated player or
the USB-X interface. This connection supports multiple audio formats.
PC: Direct USB connection to Windows based computers for sample rates
up to 48kHz. Before connecting to PC, make sure that PC input is
selected on MPS-5 and the PC is turned on, so that the PC can
enumerate the link. Subsequent changes of selected inputs on MPS-5
are then possible without disconnecting the USB cable. However, when
powering down the PC the enumeration is lost and the link has to be set
up again as described above.
AUXILIARY: Used to connect legacy USB-X interface.
System Control: SOFTWARE: This USB connection to a Windows based PC is used to update the
software of the MPD-5 converter.
REMOTE: RS-232 wired remote control (see appendix for further details).
BOOT: Used in connection with software update procedure. When pressed
during normal operation it resets the player.
Power: Before connecting the converter to the AC mains, please make sure that the rated voltage
for the MPD-5 is set correctly as indicated on the rear panel. Operating the converter at
the wrong voltage will damage the unit. The voltage rating of the power supply cannot be
changed by the user.

batteries are inserted with their
polarities as indicated in the picture.
The screws can be opened with a

CONNECTING THE MPD-5 TO A WINDOWS BASED PC or APPLE MAC
The MPD-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 MPD-5 TO A PC VIA ITS INTERNAL USB INTERFACE
Again, the MPD-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 MPD-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 MPD-5 BEFORE connecting the USB cable from the PC. This
allows the operating system on the PC to identify the MPD-5 and configure its audio port. Once the
connection has been established and the PC is not turned off the input selection on the MPD-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).

2. CONNECTING THE MPD-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 MPD-
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 MPD-5 and to exchange audio data custom driver
software needs to be installed before you can connect it to the MPD-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 MPD-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 MPD-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-XII. 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 MPD-5. If the
optical cables provided with the MPD-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 MPD-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.

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 MPD-5, make sure the optical cables are
connected as explained in the previous paragraph and connect the USB cable that was included with
the MPD-5 between USB-X and your computer. Since the USB-X interface is powered by your
computer, but receives the clock signal from the MPD-5 you must always power the MPD-5 first
before connecting the USB cable. As soon as the MPD-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.
