Product Overview
TOA's BG-2480D (480W) is a high power, D-class amplifier which is lighter, more efficient and cooler running than conventional amplifiers. The BG-2480D has 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).
This 5-input mixer amplifier is designed for background music distribution and general announcements in commercial spaces such as bars / restaurants, retail stores and hospitality facilities. It is also 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.
