The TOA CA130 30W Mobile Mixer Amplifier with Microphone is ideal for public address and emergency paging applications. This public address system is powered by a regular 12V battery and delivers 30W through four or eight-Ohm speaker loads. With the accompanying hardware, this CA130 unit can be mounted under a dashboard or into a conventional console cutout. The two microphone inputs each have their own volume settings, while the additional auxiliary input allows you to be a little more creative by allowing you to use mixed media.
