SPX Powered Mixer USB Operation
General USB Operation
With the introduction of the SPX Powered Mixer with USB, Wharfedale Pro enters the realm of digital
audio recording and reproduction. Now, with the connectivity offered by the bi-directional USB port, the
SPX powered mixer can be used as a digital interface to any computer allowing for full digital audio
recording and playback. In order to get the most from this powerful new feature please read the
following instructions carefully.
The USB port on the SPX series is a fully 2.0 compliant interface that is recognized under
RR
OO
Windows
,
Mac OS-X and other operating systems. As a Plug-and-Play device, the interface
requires no drivers or additional software to function. Simply connect the device to the computer using
a standard USB A-to-B cable, power the mixer on and follow any on-screen prompts. Once the
operating system recognizes the USB device it is ready for use.
The computer's operating system will recognize the USB device as a virtual sound card with Stereo
Output and Stereo Input. You can then play sounds out through the SPX mixer just as if it were your
R
O
computer's sound card. Simply open any audio software application (such as Windows Media Player)
and play an audio file. Note that you may have to change the audio properties to send the signal to
the SPX.
The USB port allows for the export of the Stereo mix from the SPX into the computer for recording.
The SPX output signal is derived from the Stereo Main Mix and is Pre-Fader. The signal level sent to
the computer is not affected by the SPX Main Master level control. In order to receive a signal from the
R
O
SPX simply open any audio recording application (such as Windows Sound Recorder) and set the
audio recording properties to the SPX.
Bonus Software included with the SPX
SPX models are shipped with a CD-ROM containing free audio recording and editing software. This
software is included at no charge to illustrate the power and functionality of the USB recording and
playback feature in the SPX series. It is not required for proper operation of the SPX, nor is it
necessary to use the supplied application. It is included as an introduction to digital audio recording
and editing.
