TOA MA-725F-AM 6-Input Matrix Mixer and Power Amplifier, 250W

The TOA MA-725F-AM 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-AM 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.

At its core, the MA-725F-AM 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, capable of driving large speaker compliments with maximum efficiency. A totally digital product sporting 24-Bit / 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 CAT5 cable to each of the four output channels, allowing access to volume and source select.

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.

Features:

• 4 stereo line and 2 priority MIC/LINE inputs with matrix routing to 4 amplifier outputs.
• 2 priority inputs with different priority level for paging or other audio source to override stereo line inputs.
• Each priority input has input gain level, mute sensitivity and mute hold time adjustments.
• 4 channels of 250W Class-D amplifier at 70V / 100V
• Independent DSP preset selection per each channel and 50Hz HPF for speaker protections.
• DSP preset selections include general EQs, TOA speaker EQs and X-over settings to be used with subwoofers.
• Each output channel also has auxiliary line output to deliver audio to other audio systems for scale expansions.
• Up to 4 wall mount remote control, WP-700 can be connected to control the line input selection and output volume.
• 100 - 240V universal power supply.
