Connecting the DSP to the PC
USB connection: We don´t recommend using any passive extension cable together with the included USB wire, as the
proper function can´t be ensured.
DSP setting: The GZDSP 6-8X PRO must be connected to a PC with the DSP software installed using the included USB
wire. To adjust any setting the amplifier must be in operation mode. Double click on the software icon or select from the
software list to start. The program starting window appears.
Windows
®
user account control (UAC): In case the PC operating system is set to restricted security clearance regarding
software with unknown source or without digital signature a window will appear each time at the program is starting.
Please confirm with >Yes< (language depends on your local setting) to run the program.
Setup note: The first time the GZDSP 6-8X PRO is turned on and the software is started there is no audio signal on the
output channels (RCA) available unless each channel has been adjusted.
USB connection and COM port / Windows device manager
In order to use the software, the GZDSP 6-8X 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 6-8X PRO connected to
the PC to become familiar with most of the
features and to create sample setups.
