About: TOA Canada MA-725F 6x4 Matrix Mixer Amplifier

TOA’s MA-725F matrix amplifier is an all-in-one solution for multi-zone applIcations combining a 6x4 audio matrix, DSP, and four channels of Class-D amplification in one chassis (250Wx4 @70V/100V). It is equipped with four independent line inputs, and 2 MIC/LINE priority inputs. Each output has independent DSP preset adjustments and individual source selection. The system is controlled via front panel, WP-700 remote source and volume controller, browser with computer or smart device, or any combination thereof. The MA-725F is the perfect choice for quick and easy installations requiring quality sound, intuitive operation, and flexible source to zone control.

A totally digital product sporting 24Bit/48kHz digital sound quality, its simple user-interface belies its advanced inner 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 via a single shielded CAT5 cable to each of the four output channels, allowing access to volume and source select.

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.
