Nero MX1250 DSP Matrix 12-Channel Amplifier

True 1U Multi-Zone Amplifier

Matrix Switching and DSP Control

6 Zones. Half the Rack Space. Built for Modern Installs.

The OSD Nero MX1250 is engineered for high-performance distributed audio systems, delivering six zones of powerful, efficient amplification in a true 1U rack-mount design. By combining a compact form factor with matrix switching, DSP processing, and per-zone EQ, the MX1250 gives installers the flexibility to build cleaner, smarter, and more scalable audio systems.

True 1U Design, Maximize Every Rack

Rack space is one of the most valuable resources in any installation. Traditional multi-zone amplifiers often require 2U or more, limiting system density and increasing heat buildup.

The MX1250 fits six independent zones into a true 1U chassis, allowing more equipment in less space while supporting cleaner rack layouts and improved airflow. It is ideal for residential and light commercial installations where space and efficiency matter.

Matrix Switching, Route Any Source Anywhere

Built-in matrix switching allows any input source to be routed to any zone. Whether the system needs the same audio throughout the property or different sources in different rooms, the MX1250 adapts with ease.

Whole-home audio systems

Multi-room entertainment setups

Restaurants, offices, retail spaces, and light commercial environments

No external matrix switcher is required, helping simplify system design and reduce extra equipment.

Built-In DSP, Smarter System Control

The MX1250 features integrated DSP processing, giving installers the ability to fine-tune system performance for each zone.

Optimize sound for room acoustics

Adjust performance based on speaker placement

Tune audio for residential or commercial applications

This helps deliver consistent, high-quality audio across every zone.

Per-Zone EQ, Dial in Every Room

Every space sounds different. With independent EQ control per zone, the MX1250 allows precise tuning for each listening area.

From open living rooms to smaller enclosed spaces, installers can shape the sound to help reduce harsh highs, improve clarity, or add bass where needed.

6 Independent Zones, Flexible Audio Distribution

Power up to six independent zones with dedicated control, making the MX1250 a strong choice for multi-room audio systems.

Whole-home audio distribution

Multi-room streaming systems

Light commercial audio setups

Each zone can operate independently or as part of a larger synchronized audio system.

Clean, Installer-Focused Design

The MX1250 is designed with real-world installation in mind.

Logical rear panel layout

Clearly labeled inputs and outputs

Streamlined wiring paths

Phoenix speaker connectors for secure installation

This helps reduce installation time and minimize wiring errors in complex multi-zone systems.

Efficient Digital Amplification

High-efficiency Class D amplification delivers reliable, consistent power while minimizing heat and energy consumption.

Rack-mounted environments

Continuous-use systems

Energy-conscious installations
