True 1U Multi-Zone Amplifier

Matrix Switching & 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 compact form factor with advanced control features like matrix switching, DSP processing, and per-zone EQ, the MX1250 gives installers the flexibility to build smarter, cleaner, 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 solves this by fitting six independent zones into a true 1U chassis—allowing more equipment in less space, improved airflow, and cleaner rack layouts. Ideal for both residential and 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 requires the same audio across all zones or different content in each room, the MX1250 adapts instantly.

This flexibility is critical for:

• Whole-home audio systems
• Multi-room entertainment setups
• Commercial environments like restaurants, offices, and retail

No external matrix required—everything is integrated.

Built-In DSP – Smarter System Control

The MX1250 features integrated DSP processing, giving installers the ability to fine-tune system performance at a deeper level.

Adjustments can be made per zone to optimize sound quality based on:

• Room acoustics
• Speaker placement
• Application type

This ensures consistent, high-quality audio across every zone—no matter the environment.

Per-Zone EQ – Dial in Every Room

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

From open living rooms to smaller enclosed spaces, installers can shape the sound to deliver balanced, accurate audio everywhere—eliminating common issues like harsh highs or muddy bass.

6 Independent Zones – Flexible Audio Distribution

Power up to six zones with independent control, making the MX1250 ideal for:

• Whole-home audio distribution
• Multi-room streaming systems
• Light commercial audio setups

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

This reduces install time and minimizes errors—especially in complex multi-zone systems.

Efficient Digital Amplification

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

This makes the MX1250 especially well-suited for:

• Rack-mounted environments
• Continuous-use systems
• Energy-conscious installations

Built for Modern Audio Systems

With its combination of compact design, flexible routing, and advanced audio control, the MX1250 is built to meet the demands of today’s distributed audio systems.

Whether used in residential or commercial applications, it provides the performance, control, and efficiency needed for professional-grade installations.
