- Note that this driver will download as a zipped (compressed) folder that contains 15 individual fi les.
2) Once downloaded, unzip the folder. This is done by right-clicking the folder and selecting ‘extract
all’ from the list of options.
- This will create a new folder containing the uncompressed fi les you will need.
3) Open the new folder you just created and double-click the fi le called ‘Setup’. This will begin the
installation process.
- There are two fi les named ‘Setup’. The one that needs to be clicked has an icon that looks like a
computer with a black screen. It is the only fi le with this appearance.
4) After a couple of minutes, you will be prompted to connect the device you want to install. At this
time, connect your NuWave DSD to your computer. Shortly after, your USB driver installation will fi nish.
5) To complete the entire process and begin listening to music, click Start > Control Panel > Sound.
Select the speaker icon that says ‘PS Audio USB 2.0’ as its description. Now click ‘Set Default’ and
check ‘Default Device’. Click OK. This driver was developed for PS Audio DACs and the USB input
on the NuWave DSD is identical to the DirectStream DAC.
6) Next and while still in the Control Panel click on-> Speaker Properties so the window appears, click
the Advanced tab and select the highest resolution you will be playing over the USB connection and
click OK.
If you experience a hum through the speakers this can be caused by several things. The fi rst is the
source. If there is an excessive amount of buzz or noise from the loudspeaker, it may be caused by a
ground loop, a light dimmer in the home, poor AC power, or any number of causes. The quickest way
to determine where to start your search is to simply turn the preamplifi er, integrated, or receiver off,
disconnect the audio cables between it and the NuWave DSD, and see if the hum goes away when
you turn the preamplifi er, integrated, or receiver back on. If it does, it’s most likely a ground loop or
buzz from a dimmer.
If this doesn’t solve the problem, reconnect the NuWave DSD and follow these easy humbusting tips.
The easiest way to fi gure out where ground loop problems lie is by the process of elimination. You
need to determine where the hum or buzz is coming from within your system.
If the hum/buzz goes away when you remove the inputs to the power amp, your next step will be
to reconnect the amp and move further down the chain. If you were working with a receiver or an
integrated amplifi er, you will need to jump to step 4. If you have a preamp, or processor that is feeding
the power amp, your next step would be to disconnect all inputs to the preamplifi er or processor. Once
these are disconnected, and the preamp or processor is connected only to the power amplifi er, turn
the system on and again, listen for hum. Should the hum now appear, it is a problem with your preamp
or processor or their interaction with the power amp. Before returning the preamp or processor to
