Public Address Amplifier 40W @70V/100V

The COM104 is a compact but versatile public address mixing amplifier which offers solutions for small to medium size audio systems in commercial installations. Typical applications are background music systems in retail stores, bars, restaurants, and office buildings.

The compact and simple design allows installation in any location and operation through any possible user.

The amplifier is designed using Class-D amplifier technology and delivers an output power of 40 Watt to constant voltage (100V and 70V) or low impedance (4 Ohm) audio systems. A switch-mode power supply allows compatibility with a wide variation of mains voltages for global compatibility.

A stereo line input allows connection for a wide variation of audio sources such as media players, radio tuners, internet audio players, … and many more. A balanced mic/line input allows connection for an announcement microphone with compatibility for condenser microphones using the integrated phantom power supply (15V). A priority switch overrides the background music when enabled, and compatibility with voice file players is guaranteed by the wide gain adjustment possibility (0 dB – +50 dB).

The COM104 is a table-top standing device, while rack mounting in 10.5″ or 19″ equipment racks is possible using an optionally available mounting set (MBS310).
