The PA-7250 has enhanced features. It has for example a special line for emergency announcements (such as a fire alarm) that will overrule all other inputs. It is also equipped with an adjustable chime function, ducking level control, loop through connection and a line output that can be set as line output, music only or microphone only. Besides, each zone also has its own line outputs for being able to connect extra amplifiers, allowing you to extend the PA system if needed.

This 100 V zone mixer amplifier is designed to support a PA system intended for intercommunication or background music in public and business areas such as convention halls, shopping malls, dining halls, auditoriums and recreational areas. It has an integrated protection circuit to protect against overload and short circuit of the output. This results in very high reliability and easy installations without the need for additional audio processors.
