Description

Condition: Used, fully tested, and in working condition Bogen C-100.

Product Overview:

The Bogen C100 100-Watt Public Address Mixer Amplifier is a versatile PA amplifier designed for use in both commercial and institutional environments. It provides reliable mixing and amplification for microphone, telephone, and auxiliary audio sources, making it suitable for public address, paging, and background music systems. The amplifier features four independent inputs, each with its own volume control, and includes treble and bass tone controls to adjust the sound profile for the environment.

With transformer-coupled outputs that support 4-ohm direct, 16-ohm, 25V, and 70V speaker systems, this amplifier is highly adaptable to different audio setups. The telephone input is specifically designed for paging systems, and includes voice-activated muting (VOX), allowing telephone paging to automatically mute auxiliary input. The amplifier also offers thermal protection and electronic shutdown for overload protection, ensuring reliable performance even in demanding situations.
