For a Windows computer, there are two distinct aspects to cover. One is to set up the
version of Windows you are using for the maximum audio performance, and the other is to
choose and configure your music player. We will cover the setup instructions for each of
the Windows operating systems separately.
Computer Requirements for Class 1
- Windows XP Service Pack 2 or newer.
- A dedicated, USB port for playback up to 96 kHz in Class 1 mode.
For system requirements for Class 2 audio, refer to the Going Beyond 96 kHz section under
your specific operating system instructions.
Connecting the D/A Converter
Your Ayre USB D/A converter can be configured in one of two ways. There are DIP switches on
the rear panel, with one marked "Rsrv A" and "Rsrv B". "Rsrv A" is the default and selects
Class 1 Audio, which is simple to use and will handle all music files up (and including) 96
kHz. Some users may have music files with sample rates beyond 96 kHz. Class 2 Audio ("Rsrv
B") is required for these and the more complex setup for this mode may be found on the
Operating System page specific to your setup under the section Going Beyond 96 kHz.
For typical use, Class 1 audio is recommended ("Rsrv A") and connecting to your computer is
the same regardless of which version of Windows you use. First, verify that your unit is
plugged in to AC power, that the switch on the rear panel is in the "Rsrv A" position, and
then connect the USB cable from one of your computer's USB ports to the USB port in the
back of the unit. If the you need to switch the switch from "Rsrv B" to "Rsrv A", be
certain to unplug the USB cable from either your unit or the computer, wait five seconds,
and then plug the cable back in so that it will function properly.
When connecting your Ayre D/A converter to the computer while in Class 1 Audio mode, you
may see a failed driver installation notification.
If you click on that window, you will see that it is for the Ayre DFU.
It is important to note that this is not
the USB Audio Device and this failed
installation notification may safely be ignored. Instead this notification refers to the
Device Firmware Upgrade (DFU). The DFU functions only in Class 2 Audio mode and is used to
update firmware for the Ayre USB D/A converter if required. Instructions on how to do this
will be made available should firmware updates become necessary.
For further instructions on how to connect and set up the Ayre D/A converter, refer to the
page specific to your operating system.
