VA-8150CV / VA-4300CV Setup and Installation 

Setup and Use 

The Vocia software provides an intuitive interface for configuration of the VA-8150CV and VA-4300CV 
Amplifiers. The information supplied by this manual relates to physical connections and assignment. For 
more details on software setup, please consult the Vocia Help File. 

Installation 

The unit requires one 3.5 inch (88.9mm) high and 19 inch (483mm) wide rack space with 17.5 inch 
(444mm) depth. Mounting the unit using four screws with washers will prevent marring of the front panel. 
PVC or nylon washers are appropriate. 

Install the unit away from heat sources, such as vents and radiators, and in rooms with adequate 
ventilation. Ensure that air can circulate freely behind, beside, and above the unit. Do not exceed the 
maximum ambient operating temperature of 18°-108° F (-8° - 42°C). Be aware of conditions in an 
enclosed rack that may cause the temperature to exceed ambient room conditions.
