Amplificador mezclador PA AUDAC COM12MK2 120W con salidas 100V/70V/4Ω, 2 entradas mic/3 line, alimentación prioritaria y phantom, montaje en rack 2U, Negro

For commercial audio installations that demand reliable background music and paging, the AUDAC COM12MK2 stands apart as a compact 120-watt mixer amplifier with integrated 100V, 70V, and low-impedance outputs. Unlike basic stereo amplifiers, this 2U rack-mountable unit combines a two-channel microphone mixer, three stereo line inputs, and a dedicated emergency input with priority override—making it a complete single-zone PA solution without external mixers or complicated wiring. Its convection-cooled design ensures silent operation, ideal for offices, retail spaces, restaurants, and educational facilities.

Highlights

• 120 W RMS output power with selectable 4 Ohm, 70V, and 100V speaker outputs for flexible speaker configurations.
• Two balanced microphone inputs (XLR/TRS combo) with individually switchable phantom power for condenser microphones.
• Three unbalanced stereo RCA line inputs for connecting media players, TV, or background music sources.
• Dedicated Euroblock emergency input with automatic priority over all other sources for paging or alarm messages.
• Mic 1 priority function with adjustable level, ensuring announcements always cut through background music.
• Built-in bass and treble tone controls for tailoring sound to the room acoustics.
• Comprehensive protection circuits against overload, short circuit, and overheating for long-term reliability.
• Convection cooling (no fan) for silent operation in noise-sensitive environments.
• 2U rack-mount form factor with black metal housing, blending into professional AV racks.

In daily use

Installation is straightforward: connect your speakers to the appropriate output terminal (low impedance for a few local speakers, or 70V/100V for distributed ceiling speakers), plug in microphones and line sources, and set levels with the front-panel controls. The priority function on Mic 1 and the emergency input ensures that announcements or alerts automatically duck or mute other audio, a critical feature for safety and communication. The front panel provides individual volume controls for each input, master volume, and tone adjustments, while LED indicators show signal presence and protection status. Because it uses convection cooling, there is no fan noise to disturb quiet spaces, and the amplifier can be mounted in a standard 19-inch rack using 2U of space.
