The OSD Audio PA90 Commercial Integrated Pre AMP/ 60 Watt Power Amplifier is the ideal control center for restaurants, meeting halls, schools or other small, commercial venues where multiple microphones and line audio sources are needed. This versatile, powerful and affordable commercial amp features 3 XLR microphone inputs and 3 signal-level inputs, plus front-mounted gain control knobs, master bass, and treble. An upgrade typically found on more expensive commercial amps, the PA90 also features chime and alarm buttons. The chime button temporally mutes the system when pressed, while the alarm mutes the system and rings until the button is released. The PA90’s XLR microphone inputs and signal level inputs can be connected to sources like CD players, TV outputs, Smartphones, MP3 players, and the unit even includes a telephone input. The amp’s output options (70 Volt, 100 Volt or 8-ohm mono) can also be set up to power 5 to 10 speaker 70V systems.
