The BG-1120, part of the BG-M series of mixer/amplifiers from TOA Electronics, is a high-quality, compact unit ideal for paging, background music, and on-hold applications in schools, hospitals, restaurants, offices, and other similar venues. It has microphone, telephone, program, and aux inputs, as well as an input module slot, which accepts TOA 900 Series connector modules so that you can customize the BG-1120 to meet your needs. Outputs include balanced screw terminals for 4 ohm, 25V and 70V, as well as a line-level music-on-hold output and a 1W output for an 8 ohm speaker zone.
The BG-1120 has an auto-mute function which allows voice-activated paging without interrupting the MOH output. Bass and treble controls are provided, and each input has an individual volume control. Internal protection circuitry helps prevent damage from overheating, overloads, and short circuits.
