If no sound comes out of the system with the NWD connected, there are several areas to check.
Either you are not getting an audio signal into the preamplifi er, or you don’t have a good digital source
feeding the NWD.
First, check to make sure your preamp, integrated, receiver or Control Amplifi er is switched to the
same input the NWD is connected to. Test the connection and the cables to make sure. Keeping the
input selected and using the same cable, connect this input to a known good source like a tuner or
the direct analog output of a CD player. If that works, then it is most likely not a connection problem
between the NWD and the preamp, integrated, receiver or Control Amplifi er.
Next step is to check and see if the digital input is properly connected. Look on the front panel of
the NWD to see if the locked light is illuminated. If it is not, this is most likely the problem. You can
troubleshoot this by making sure the NWD is on the proper input and that you have connected the
input correctly. If this fails, try replacing the digital interconnect or try using another type. For instance,
if you are using a coax connection, try using the CD player’s optical output instead or try replacing the
cable.
If you are using a USB connection, it is necessary for the computer to recognize the NWD as a
connected device through a driver. if you are using a Mac the driver is already installed and if you’re
using a Windows computer you will need to install the driver (see below). If you have the driver
installed and cannot play using USB, check in the computer’s control panel under USB devices and
see if the NWD is recognized (it will be called PerfectWave). If not, with both the NWD and your
computer powered up, remove the USB cable from the computer and then re-insert it. Watch the
computer monitor for an indication it has found the hardware.
The new 192kHz asynchronous USB input on the NWD will require a driver to work.
If you are running on a Mac, this driver is already built in. Just plug the USB from the Mac into the
NWD and you should be fi ne although you will have to go to System Preferences->Sound and select
the PerfectWave device to play to it. The NWD uses the PerfectWave driver and thus the computer
recognizes it as a PerfectWave device.
For Windows users, download this fi le to your desktop, then follow the instructions:

A couple things to consider here regarding this driver:
- This driver is specifi cally designed to work with your NWD.
- This driver is designed to work on all Windows XP, Vista and Windows 7 computers.
- If you have a Mac running OS X Snow Leopard 10.6.3 or later, your computer already has this driver
built in, and you’re good to go. 10.6.3 was released in March of 2010.
Please note that this walk-through is only for computers running Windows 7.
