Key Features: This Bogen 35-watt wall-mounted telephone paging amplifier offers multiple inputs, including a 600-ohm balanced telephone line, Lo-Z balanced microphone, and background music input (RCA jack or screw terminals). It has an integral automatic level control (ALC) circuit, allowing for clear paging regardless of voice levels and techniques. You can page from the telephone and/or microphone, and the signal-activated paging channel automatically mutes background music, with an adjustable muting level. After a page, the music gradually returns to normal. The audio enhancement circuit boosts intelligibility, improves perceived loudness without extra power, and reduces listener fatigue. There are separate controls for page volume, music volume, night ringer, music mute, and audio enhancement, along with bass and treble controls. The built-in night ringer can be activated by contact closure or a 90V ring signal. Balanced or unbalanced 16-ohm, 25V, 25V CT, and 70V outputs are available for select models. VOX sensitivity control prevents accidental noise transmission. It has thermal and electronic overload protection, and jacks for bridging additional TPU amplifiers. All models come with brackets for easy wall mounting, and some can be rack-mounted. Peak level indicator lights up when the amplifier is over-driven. It runs on a 120V AC, 60 Hz power source and is UL Standard 60065 listed for the U.S. and Canada.
Using your Bogen 35W amplifier is easy. First, connect your devices to the appropriate inputs - like a phone line, microphone, or music source. Adjust the volume controls for pages and music according to your needs. You can also fine - tune the bass and treble for better sound quality. To use the night ringer, connect it using contact closure or a 90V ring signal. When paging, the amplifier will automatically mute the background music, and you can set the muting level. After paging, the music will gradually come back to normal. Remember to place the amplifier in a well - ventilated area to avoid overheating as it has thermal and electronic overload protection. Check the connections regularly to ensure stable performance. If you want to expand your system, use the jacks to bridge additional TPU amplifiers. When not in use, unplug it from the 120V AC, 60 Hz power source to save energy and prevent potential electrical issues. And since it's UL Standard 60065 listed, you can be confident in its safety and quality.
