TOA Electronics BG-2240D 240-Watt Class-D 5-Channel Mixer/Amplifier

The BG-2240D (240W) is 5-input mixer amplifiers designed for background music distribution and general announcements in commercial spaces such as bars/restaurants, retail stores and hospitality facilities. They are each equipped with an MOH output that permits two independent zones when used in conjunction with an optional external power amplifier with a line level analog audio input. It uses D-class amplifiers which are lighter, more efficient and cooler running than conventional amplifier and have the same basic feature set as analog BG-2000 models, including: Dual balanced priority mic/line inputs, dual unbalanced line inputs, assignable 2nd zone/MOH output, front panel bass and treble controls, remote volume control port, assignable mute function and a 900 series input module slot (output modules not compatible).
