This multi-channel matrix system features high power (250W x 4 at 70 V/100 V) and various inputs capabilities.

Its wide range of applications include general or emergency announcement and background music for restaurants,pubs, retail stores, schools, offices etc.

At its core, the MA-725F is a 6-input matrix mixer: 4 of its inputs are configured for BGM or other line-level sources, while two balanced inputs are designated for priority sources, such as paging mics or message players.

This is coupled in a single chassis with a 4 x 250W (@70 or 100V) Class D amplifier section, capable of driving largespeaker compliments with maximum efficiency.

A totally digital product sporting 24Bit/48kHz digital sound quality, its simple user-interface belies its advancedinner workings.

The only controls any user needs to access are the front panel source select buttons and four output level (zone) controls.

All other controls are placed on the rear panel to prevent unauthorized tampering.

An optional wall control (WP-700-AM) can be connected viaa single shielded CAT5 cable to each of the four output channels, allowing access to volume and source select.

The digital mixer section also features a menu of 26 TOA speaker EQ presets (selectable by dip-switch), factory-loaded, to optimize the sound of our most popular PAand audio speakers.

It also provides settings to allow bi-amping with subwoofers and offers many popular audio playback EQ curves.

TOA will also offer a non-powered Matrix Mixer version (MM-700F) for use with external amplifiers to allow for customized power selection.

The MA-725F matrix amplifier performs matrix controls from 4LINE plus 2 MIC/LINE level inputs to 4 output channels.

Each output channel features 64 DSP preset selections forgeneral equalizations, crossover for sub-woofers, or a variety of TOA speakers’ EQ settings.

2 MIC/LINE inputs have 1st and 2nd priority levels which can override assigned output channels automatically or manually.

If connected with optional WP-700-AM wall remotes via shielded CAT-5 cable, audio source selection and volume controls can be done remotely.

All assignments and setups can be done by dip switches onits rear panel without a laptop or a PC.

This unit fits a wide range of applications that require multi-zone paging and/or background music distribution at restaurants, retail stores, factories, and many other venus.

The WP-700-AM is a remote control switch/volume panel that is designed for the MA-725F mixer amplifier, which can remote select input source and adjust volume levels when connected via a shielded Ethernet cable to the MA-725F mixeramplifier. .
