d:24

sonible’s d:24 multi-channel amplifier delivers brilliant sound for high-end audio installations in science, research, industry and other applications: reliable, true to the signal, compact and unique in its class.


  • 24 x 250 Watts of power

  • Completely noise-free with SNR > 112dB per channel

  • Multi-channel amplification at only 3 RU

Features

Precision meets design


Analog & digital

Flexible Interfaces

As a true team player, the d:24 effortlessly cooperates with pre-installed systems. The analog inputs of the base model are expandable with three different digital input options: MADI (coaxial and optical), DANTE and AES/EBU. All digital modules are equipped with high-end D/A converters and allow free routing of every single channel. The good news: the modules can easily be retrofitted.




 

All-in-One

DSP power inside

For maximum comfort with every installation, the d:24 comes with a set of convenient signal processing tools. The optional DSP module offers an equalizer, a compressor, a limiter, and a delay. Even with complex installations, the multi-channel amplifier can thus function as a compact all-in-one solution.


The DSP option turns the d:24 into a flexible partner for implementing compact systems with a large number of speakers – for example, when working with modern 3D audio formats such as Higher Order Ambisonics (HOA) or Wave Field Synthesis (WFS).



Web based interface

Simple remote control

All settings of the d:series amplifiers can be remote-controlled via Ethernet connection and a web interface. The web-based control allows for making instant adjustments to the system. Additionally, the d:series amplifiers can be integrated in automation systems via a RESTful API.


For critical development work or sensitive installations, the d:24 additionally features an emergency stop. All channels can be deactivated via an optional hardware switch connected to the amplifier without having to deal with software.
