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 80 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 COM108 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).
