Dali Phantom CI AMP-4125 DSP 4-Channel CI Amplifier

The Dali CI AMP-4125 DSP 4-Channel CI Amplifier Cable Upgrade is designed as a dedicated amplification and processing solution for custom installation environments. Developed specifically to partner DALI in wall and in ceiling loudspeakers, it focuses on delivering consistent, predictable sound quality with minimal setup complexity.

Its compact half rack, 1U chassis allows easy integration into equipment racks or discreet placement within cabinets, making it suitable for residential and commercial installations alike.

The amplifier is intended to simplify system design while maintaining high performance standards, offering installers and integrators a reliable platform that supports both stereo and multi-channel configurations. By combining amplification, DSP, and speaker-specific optimisation in a single unit, it provides a streamlined approach to modern custom audio systems.

Integrated DALI Speaker Presets

A key feature of the CI AMP-4125 DSP is its integrated DALI speaker presets, designed to remove uncertainty from system tuning. Each preset is carefully developed to match the acoustic characteristics of compatible DALI CI loudspeakers, ensuring balanced tonal response and controlled dynamics from the outset.

This approach reduces installation time and minimises the need for manual calibration, delivering consistent results across multiple projects. By applying speaker-specific processing within the amplifier, the system achieves predictable and repeatable performance regardless of room size or application.

The result is a more efficient workflow for installers and a reliable listening experience for end users, with sound that reflects DALI’s intended voicing without extensive adjustment.

Compact Power with Class D Efficiency

Despite its modest physical dimensions, the CI AMP-4125 DSP delivers substantial output through an efficient Class D amplifier platform. It provides four channels of 125 watts into 4 ohms, with the option to share power or bridge channels to deliver higher output where required.

This flexibility allows the amplifier to adapt easily to different speaker loads and system layouts. Designed and developed in Denmark, the amplification stage prioritises low distortion, high dynamic range, and thermal efficiency.

This ensures stable operation in continuous use scenarios such as distributed audio or commercial environments, while also supporting the demands of home cinema surround and height channels without excessive heat or power consumption.

Comprehensive DSP Control Interface

The amplifier includes a fully featured DSP suite that offers precise control over system behaviour. Functions include equalisation, routing, delay, limiters, and compressors, allowing fine tuning to suit both the loudspeakers and the installation environment.

Configuration is handled through the DALI AMP CONFIGURATOR, a web-based interface accessible from any Wi Fi enabled device. This allows quick setup, easy adjustment, and reliable recall of settings without the need for additional software.

The interface is designed to be intuitive for installers while offering sufficient depth for advanced configuration. This level of control ensures that each channel can be optimised accurately, supporting consistent performance across complex multi-channel systems.

Connectivity and Installation Flexibility

The CI AMP-4125 DSP is designed to accommodate a wide range of system requirements through its extensive connectivity options. It offers balanced and unbalanced analogue inputs, digital inputs and outputs, and support for both low impedance and high impedance speaker systems.

This makes it suitable for residential cinemas, multi-zone audio systems, outdoor installations, and commercial spaces such as hospitality and fitness environments. Flexible mounting options allow rack installation or free-standing use, depending on project needs.

Network connectivity via Wi Fi or LAN supports control and monitoring, while trigger and GPIO functions allow integration with wider control systems. These features make the amplifier adaptable to diverse installation scenarios.

Role Within the DALI CI Ecosystem

Within the DALI custom installation ecosystem, the CI AMP-4125 DSP serves as a central building block for complete system solutions. It is designed to work alongside DALI CI loudspeakers, providing amplification, processing, and speaker optimisation in a single unit.

Positioned as a versatile and cost-effective solution, it supports everything from simple two-channel installations to immersive multi-channel and distributed audio systems. The amplifier is equally suitable as a dedicated power and DSP solution for use with AV processors or as part of a fully integrated DALI CI setup.

By combining performance, flexibility, and simplified configuration, it addresses the practical needs of modern custom installation projects.
