Software Application Guide 

 
The CLA-300 is supplied with a CDROM containing software. This software is also available for 

download from 

www.avsl-citronic.com/product/171.227UK

 

 

System Requirements 

 

PC running Microsoft Windows XP or above. 
Display resolution 1024 x 768 or above 

USB or RS-232 port 

 

Connection to PC 

 

 

Connect directly to PC via USB using the supplied cable. The PC will find a “new device”, 

prompting the computer to look for driver software. The driver file is included on the CDROM 
(Browse to the “Driver” directory) 

 

If USB connection is not available, serial port link can be made from the RS-232 input on the 

rear panel using the supplied D-connector lead, again requiring driver installation from CDROM 

 

For PCs with an RS-485 interface using XLR connection, this can be used to connect from the 

PC to the CLA-300 and passed from one CLA-300 to another using the RS-485 output 

connector 

 

Software Operation 

 

Install the software (Active Speaker Controller.exe) from CDROM or download and run from the start 
menu or desktop shortcut. The user interface window will appear as shown below.
