TOA Electronics Multi-Channel Matrix Amplifier - MA-725F-AM 3CU

Overview

The TOA MA-725F is a 4-zone all-in-one matrix amplifier combining a 6×4 audio matrix, DSP, and four 250 W Class-D amplifier channels in a single chassis. Operating at 70V or 100V, it drives up to four independent speaker zones from up to six audio sources — making it an efficient, compact solution for restaurants, retail stores, offices, and schools.

Description

The MA-725F eliminates the need for separate mixer, DSP, and amplifier components by integrating all three into one unit. Four stereo-summing line inputs and two priority MIC/LINE inputs are routed through a 6×4 matrix with independent DSP preset selection per output channel. Each output channel features a 250 W Class-D amplifier, auxiliary line output, independent 50 Hz HPF for speaker protection, and individual volume control. DSP presets include general EQ curves, loudness curves, TOA speaker EQ, and subwoofer crossover settings. Smart Control enables browser-based wireless remote control without requiring dedicated software, and the optional RM-9012C remote microphone adds 12-zone paging capability.

FAQ

Can the MA-725F replace a separate mixer, DSP processor, and power amplifier?
Yes. The MA-725F integrates all three functions in a single unit, simplifying installation and reducing rack space requirements for 4-zone commercial audio systems.

What is the maximum number of speaker zones supported?
The MA-725F supports 4 independent amplified output zones. With the optional RM-9012C remote paging microphone, announcements can be directed to any combination of the 4 zones.

Does Smart Control require a dedicated app or software?
No. Smart Control uses a standard web browser for wireless remote control — no software installation is needed.

Is the MA-725F compatible with 8Ω speakers?
The MA-725F outputs at constant-voltage 70V or 100V for use with transformer-tapped distributed speakers. For 8Ω direct-drive applications, see the Creation Networks audio amplifier range.
