AUDAC COM104 40W Public Address Amplifier 70V/100V/4 Ohm

The AUDAC COM104 is a versatile and compact public address mixer amplifier engineered for small to medium-sized audio installations in commercial environments. Leveraging efficient Class D technology, it delivers a reliable 40W RMS of output power, compatible with 70V, 100V, and standard 4-ohm low impedance speaker lines. Its integrated switch-mode power supply ensures broad compatibility with global mains voltages from 100 to 240V AC, making it a flexible solution for international installations.

This amplifier is designed for clarity and reliability, featuring a high signal-to-noise ratio (SNR) of 90dB and a low total harmonic distortion (THD) of less than 0.5%. Its wide frequency response from 20Hz to 20kHz ensures faithful audio reproduction for both music and speech. Comprehensive protection circuitry safeguards against DC offset, short circuits, overheating, and overload, while built-in signal limiting prevents distortion.

Connectivity and Control

The COM104 offers versatile input options to accommodate a wide range of audio sources. These include a balanced microphone/line input with 15V phantom power on a 3-pin Euro terminal block for announcement microphones, a stereo RCA input, and a 3.5mm stereo jack input for devices like media players, tuners, or internet audio players. A dedicated priority function allows a microphone or other priority source to automatically override background music, which is essential for making clear announcements. The unit also features a priority mute contact for integration with external systems and is convection cooled for silent, maintenance-free operation.

Ideal Applications

Perfect for background music and public address systems in retail stores, bars, restaurants, offices, and educational facilities, the COM104 provides a professional, all-in-one audio solution. Its compact design and comprehensive feature set make it equally suitable for live events, hobby,
