AEQ FORUM
Digital audio mixer for broadcast applications
31
When you connect a USB module to a PC through any of the USB ports, the PC will
automatically recognize it as a new audio device (it will be shown as “USB Audio CODEC”). To
this device you can send audio from any audio playback application in the same way as if it was
an external professional audio board. It is also possible to record any audio from the mixing
console in the computer by using any recording application.
These boards are “plug&play” on Microsoft Windows™ and Apple Computer Mac OS™
operative systems, no specific driver is needed. When you connect several USB ports from one
or several USB modules to the same PC, the operative system will show a new audio device for
each one, that will be identified as “USB Audio CODEC”, “USB Audio CODEC (2)”…
Supported sampling frequencies are 32 KHz, 44.1 KHz and 48 KHz, with sampling rate
converters (SRC) to 48 KHz that corresponds to the internal sampling rate of the system.
IMPORTANT NOTE: It’s necessary to use shielded cable in order to establish connection
between USB module and PC.
