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.
