The CPA-5120 C is a compact and versatile public address amplifier from the CPA-5000 series, designed for professional voice evacuation and paging systems. With a powerful 120 W RMS output and five independently adjustable speaker zones, it offers full flexibility for complex ELA installations.

The unit supports both 100V and 70V speaker lines as well as a low-impedance 8-ohm output. Multiple input options include balanced microphone inputs with switchable phantom power, switchable line inputs, and dedicated AUX inputs for media sources. A regulated electronic mic priority on Input 1 and contact- or voice-activated priority on other channels ensure intelligent input management.

Additional features include remote-triggered chime and siren functions, tone control (bass/treble), and cascading options via AMP-IN and PRE-OUT. Up to three MS-050P paging consoles can be connected. A front-panel slot allows optional installation of a media module such as a tuner or MP3 player, further expanding the system's capabilities.
