Monacor PA-312 PA Mixing Amplifier 100V Sound System Speaker PA



PA mixing amplifier with connections for 4 to 16-ohm speakers, suitable for use with 70 or 100-volt systems.



The versatile PA-312 mono amplifier by Monacor is suitable for use in any public area. It has connections for 4 to 16-ohm speakers and is suitable for 70 or 100-volt systems as well. This enables you to use all three outputs; for example, in small spaces or when you need to bridge greater distances. You can connect three microphones in total, and the one on the front overrides the others. If your mic requires phantom power, connect it to input 2, which is equipped with +48 volts. The PA-312 comes with rack ears so you can easily mount it in a 19-inch rack.
