proper function can´t be ensured.

Setup note: The first time the GZDSP 4.80A-PRO is turned on and the software is started there is no audio signal on the
output channels (RCA) available unless the channels are activated in the software.
USB connection and COM port / Windows device manager
In order to use the software, the GZDSP 4.80A-PRO must establish a communication to the PC. Therefore, an unused
USB port is required. During the connection of the USB cable the system will assign automatically a USB port. To avoid
misbehavior during the communication, it´s recommended to select a COM port number between 1 and 9. The
assigned COM port number can be checked at the system´s device manager. The GZDSP unit will appear as “USB-
SERIAL CH 340” device (at the COM&LPT list). The COM port can be changed at the properties manually if necessary.
Demo Mode (offline mode): The software
can be used in offline mode without
having the GZDSP 4.80A-PRO connected
to the PC to become familiar with most of
the features and to create sample setups.
Select >Yes< when the start window
appears.
