inDESIGN MPA-500 500W 6-Zone Mixer Amplifier (2RU)

The inDESIGN MPA-500 is a 500W multi-zone mixer amplifier built for installations that need independent audio control across multiple areas. Alongside a 100V/70V/4Ω master output, it provides 6 global zone outputs, each with its own 5-step attenuator (up to 200W per zone @ 100V).

Six input channels - three balanced mic/line with 24V phantom power (channel 1 with VOX priority) and three unbalanced line - feed into the mixer, along with a transformer-isolated telephone paging input and onboard tone generator (chime, bell, alert, evac). A built-in media player adds DAB+/FM radio, USB (MP3/WMA) playback and Bluetooth 5.3 streaming with a renameable device ID.
