OSD Nero MX1250 DSP Matrix 12-Channel Amplifier, 6-Zone Multi-Room Audio System for Whole Home Audio

The OSD MX1250 is a powerful 6-zone, 12-channel distribution amplifier designed to deliver high-quality audio throughout your entire home or commercial space. Built for flexibility and performance, it allows you to play the same source everywhere or different audio in each room—all with independent control over volume, source selection, and sound tuning. Whether you're building a whole-home audio system or upgrading an existing setup, the MX1250 provides the reliability, efficiency, and scalability needed for modern multi-room audio.

Features

• 6-Zone / 12-Channel Amplification for powering up to six independent audio areas
• Matrix-Style Source Routing with Bus 1, Bus 2, and dedicated inputs per zone
• Independent Volume & EQ Control (bass, mid, treble) for each zone
• DSP-Controlled LCD Display with front panel access to zone, source, volume, and EQ settings
• High-Efficiency Class D Design for powerful output with low heat
• Auto Signal Sensing & 12V Trigger for seamless system integration
• Rack-Mountable 1U Design ideal for clean, professional installations

Front Panel DSP Control & EQ Customization

The MX1250 features a DSP-driven front panel control system with an integrated LCD display, giving you precise, real-time control over every zone. Using the intuitive interface, you can easily adjust volume, source selection, and 3-band EQ settings (bass, mid, treble) directly from the unit. The built-in DSP ensures accurate sound tuning and consistent performance, while the clear display allows you to monitor settings at a glance. With independent EQ control from -12 dB to +12 dB per zone, you can tailor audio to match each room's acoustics—enhancing bass in larger spaces, softening highs in reflective rooms, or dialing in a balanced sound for everyday listening.

Matrix Audio Control

The MX1250 features matrix-style audio routing, giving each zone the ability to select from multiple sources, including Bus 1, Bus 2, or a dedicated local input. This means you can send the same music throughout your entire home or assign different sources to each room—all from a single amplifier. This flexible architecture makes it easy to adapt your system to changing needs, whether you're streaming music, connecting TVs, or integrating multiple audio sources.

Power Per Zone

Each zone of the MX1250 is powered by a dedicated stereo amplifier delivering 50W RMS (100W peak) per channel at 4 ohms and 25W RMS (50W peak) at 8 ohms, providing clean, consistent audio performance for in-ceiling, in-wall, or outdoor speakers. This ensures every room receives reliable power without distortion, whether you're playing background music or filling larger spaces with sound. For applications requiring additional output, Zone 6 can be bridged to deliver 100W RMS (200W peak) at 8 ohms, offering increased power for more demanding speaker setups.
