DESCRIPTION
The MA-725F matrix amplifier performs matrix controls from 4 LINE plus 2 MIC/LINE level
inputs to 4 output channels. Each output channel features 250W at 70V/100V class-D digital
amplifier with 64 DSP preset selections for general equalizations, crossover for sub-woofer, or
variety of TOA speakers' EQ settings. 2 MIC/LINE inputs have 1st and 2nd priority levels which
can override at assigned output channels automatically or manually.
If connected with optional WP-700-AM wall remotes via CAT-5 cable, audio source selection
and volume controls can be done remotely. All assignments and setups can be done by
dip switches on its rear panel without a PC.
This unit fits a wide range of applications that require multi-zone paging and/or background music
distribution at restaurants, pubs, retail stores, factories, etc.
