Wall-mounted telephone paging amplifier rated at 35 watts. This amplifier permits paging from telephone and/or microphone. Music input through an RCA jack or screw terminals. Voice-activated, variable level, music mute with fade back after page. Includes a night ringer which sends an electronic ringing tone signal through all speakers, alerting personnel of incoming calls during non-business hours. Jacks are also provided to bridge two TPU amplifiers to double the number of inputs and outputs. FEATURES
• Inputs for 600-ohm balanced telephone line, LO-Z balanced
microphone, and background music
• Music input (RCA jack or screw terminals)
• Integral automatic level control (ALC) circuit for controlling
pages made by persons with varying voice levels and paging
techniques
• Page from telephone and/or microphone
• Signal-activated paging channel automatically mutes background
music
• Adjustable background music muting level during a page
• Music gradually returns to its normal level after a page
• Aphex® Aural Exciter increases intelligibility, improves
perceived loudness (with no increase in power), and reduces
listener fatigue
• Separate controls for page volume, music volume, night ringer,
music mute, and Aphex® Aural Excite TECHNICAL SPECIFICATIONS
