paging input and a 600W line level balanced input with both inputs controlled by a tamper-resistant volume control

located on the rear panel. A Hi-Z unbalanced Aux input with parallel RCA input connectors is provided for a music

program source input. A unique music ducking circuit mutes the aux music input when a page signal is present at

either the telephone paging input or the 600W line level balanced input. The mute circuit may be defeated by

removing the chassis cover and changing a circuit board jumper. A paging horn protection (  
