• Transformer-isolated, balanced line-level input
• 600-ohm or 10k-ohm (jumper selectable) input impedance
• Transformer-isolated, balanced line-level output
• 8-ohm, 0.75W output
• Input and output level controls
• Relay responds to jumper selectable priority level
• N.O. or N.C. jumper-selectable relay contact
• External control of priority muting buses
• Input can be muted from higher priority modules, with signal fade back
• Output (normally gate) can be synched with priority relay operation
• Output gating can be defeated via jumper
• RJ11 connection with line output and dedicated N.O. relay contact (allows easy connection to O/R
port of Bogen telephone paging interfaces)
