The CA-115 is a 15W mobile mixer/amplifier for public address and emergency paging applications. The CA-115 works on a standard 12Vdc battery and cranks out 15W of power into four or 8 Ohms speaker loads. This unit mounts conveniently under a dashboard or into a standard console cutout with the included hardware. The two microphone inputs with individual volume controls give you great flexibility while the additional auxiliary input lets you get a little bit more creative by giving you mixed media capabilities.
