Matrix Mixer/Amplifier

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 large speaker compliments with maximum efficiency. It has capability to control by API.



The new TOA MA-725F Matrix Amplifier is developed from years of experience providing mixer-amplifiers for the retail industry (with a client list that’s a virtual “who’s who” of retail) and with the cooperation of some of its top players, the MA-725F is designed to address the demand for a simpler and more cost-effective, mid-level background music and paging systems needing higher power with multiple zones.  Just as advanced as some of its high-priced kin, but without the complicated setup or programming required by many other solutions.

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 PA and 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 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 mixer amplifier. It can also be mounted in a 1-gang electrical box (American type).

The browser Control feature allows password protected control of source, volume control and options from a browser on your PC (Internet Explorer, Google Chrome, Firefox, etc.).  Smartphones (iOS or Android devices) using a browser function are also supported.
