Sony MZ-R55

The PCLink’s volume and output controls can be accessed by double 
clicking the standard volume control icon. Depending on what media 
player you are using, for most of the PCLink’s operations the volume 
will be set either by the Wave Balance slider or the Speaker 
Balance slider. To activate the Wave Balance and Speaker 
Balance sliders, go to Options and then Properties. In the bottom 
section of the Properties window, make sure a check appears next to 
Wave Balance and Speaker Balance. Click OK once you are 
done.

Before plugging in the PCLink for the first time, you will need to 
ensure that your computer is running the necessary operating 
system and apple audio extensions.

To verify that your computer is running the correct operating 
system, close all open applications. Click on the apple icon in the 
top right had corner of the screen. Scroll down to the first item in 
the pop up menu called About This Computer and click on it. A 
window with details of the operating system currently running on 
your computer will now open. Verify that in the version line, a 
number 9.04 or higher appears. If this, or a higher number 
appears, you are running an operating system that is compatible 
with the PCLink. If you are running an earlier version of the Mac 
operating system, your PCLink may not operate.
