Description
Model PA2 is our premium paging switch. It has a ‘hang up’ detection circuit, so that calls are automatically terminated after hang up.
PA2+ has an internal line isolation unit (LIU), which means that you connect PA2+ direct to the amplifier with the supplied RCA cable.
An anti-pop circuit is integrated within PA2+ to eliminate or greatly reduce the ‘pop’ that can be experienced by a small number of amplifiers when a paging call is connected.
An anti-hum circuit is integrated within PA2+ to which will eliminate or greatly reduce the ‘hum’ that can occasionally be induced into audio systems from earth loop issues or electromagnetic interference from nearby equipment.
