d:24

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


  • 24 x 250 Watts of power

  • Completely noise-free with SNR > 110dB per channel

  • Extremely compact 3D audio and multi-zone amplification at 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

Thanks to Ethernet-interface and web-applications, all of the amplifier’s features can be remote-controlled. The web-based control makes it possible to make instant adjustments to the system from any location. The DSP option can be remote-controlled in the same way.


For critical development work or sensitive installations, the d:24 additionally features an emergency stop. All channels can be deactivated via the 6.3 mm connector/jack without having to deal with software.
