TOA Electronics Digital mixer - M-9000M2 CU
The TOA M-9000M2 CU is an 8×8 modular digital matrix mixer designed as the central processor for the TOA M-9000 Series commercial audio distribution system. It accepts up to eight input channels via plug-in modules (analog or digital), delivers two balanced stereo output buses, and provides comprehensive DSP signal processing—including 10-band parametric EQ, high-pass/low-pass filters, adjustable delay, and 32 scene memories—all within a 3U rack-mountable chassis.
The M-9000M2 CU is built around an open-slot architecture: each of its eight input module slots accepts either an analog input module (−10 dBV unbalanced) or a 24-bit/48 kHz digital input module, giving integrators the flexibility to match the signal chain to the installation. The unit's two balanced mix outputs and two optional digital output modules (24-bit/48 kHz) ensure compatibility with a wide range of power amplifiers and digital signal processors downstream. RS-232C control with Crestron and AMX compatibility allows seamless integration into third-party control systems. Four logic control inputs and four logic control outputs support contact-closure automation, and two remote volume channels enable distributed volume control without additional hardware.
Suited for corporate boardrooms, hospitality venues, houses of worship, education facilities, and multi-zone retail environments where centralized audio routing and recall of programmed scenes is essential to consistent system performance.
Key Features
| Feature | Benefit |
|---|---|
| 8-Channel Modular Input Architecture | Mix analog and digital inputs in any combination using plug-in modules, adapting to diverse signal sources |
| 2 Balanced Mix Outputs | Drive power amplifiers or zone processors directly with low-impedance, noise-resistant balanced signals |
| 10-Band Parametric EQ per Input Channel | Precisely tune frequency response to compensate for room acoustics or source colorations |
| HPF/LPF at −12 dB/octave | Eliminate unwanted low-end rumble or high-frequency noise without external filtering hardware |
| 0–40 ms Adjustable Delay | Time-align speakers in distributed systems to eliminate slap echo and phase cancellation |
| 32 Scene Memories | Recall entire mix configurations instantly, ideal for multi-use rooms and repeatable events |
| RS-232C Control (Crestron / AMX Compatible) | Integrates directly with industry-standard room control systems for single-button operation |
| 4 Logic Inputs + 4 Logic Outputs | Automate system functions via contact-closure events (e.g., mute on PA, source switching) |
| 2 Remote Volume Channels | Allow zone-level volume adjustment from remote panels without additional hardware |
| 90 dB S/N Ratio | Delivers clean, low-noise audio across all zones and signal levels |
Typical Applications
The TOA M-9000M2 CU is specified for corporate conference centers and boardrooms requiring scene-recall automation, houses of worship with multiple input sources and zone outputs, hospitality venues distributing background music and paging to multiple zones, education facilities needing room-combining and DSP-corrected audio, and multi-zone retail or healthcare installations where centralized RS-232C control is mandatory.
