USB Audio Interface
The ZED is equipped with a stereo bi-directional USB 1.1 compliant audio CODEC. It is fully compliant with USB 2 ports
and uses standard Windows and MAC Core Audio Drivers. In other words, plug it in and your computer will find it and
be able to transfer audio to and from the ZED USB device.
You will need some form of audio software running on your computer to be able to record and play back what you re-
cord, but on a basic level, you can use your computers media player to play straight to the ZED device.
Just a couple of points to look out for:
Windows XP/Vista:
When you plug in your ZED USB interface to your computer, if the volume level is low or
inaudible, check the device volume in control panel/Sounds and Audio Devices/Volume. Set the volume to High.
Windows 7:
At present, Windows 7 treats the USB audio device as a microphone source instead if a line input, so
set the device volume level much lower, we found setting to 3 is ideal.
If you want to reduce latency (delay) there are some different drivers available for your operating system. Please check the
Allen & Heath website www.allen-heath.com for details and links to third party companies able to supply appropriate driv-
ers for your operating system.
