DAD AX24

Second-hand. In excellent conditions. No visible signs of wear. Includes original packaging and connection cables.

Equipped only with the D/A conversion module, making it usable exclusively as a DAC.

The Digital Audio Denmark AX24 converter is a state-of-the-art solution for A/D and D/A conversion, designed to provide precision and flexibility for professional recording and mastering applications. Thanks to its modular architecture, it offers up to 224 different configurations, allowing the user to tailor the input/output structure and sample rates precisely to their workflow. The number of analog channels, both input and output, can range from 2 to 8 depending on requirements, and the modular structure allows for expansion in pairs, making it easy to customize for any operational context—from multitrack recording to 5.1 monitoring.

The audio quality is impeccable, with 24-bit PCM conversion up to 384 kHz, support for DXD at 352.8 kHz, and DSD at 64fs and 128fs, meeting the highest standards of high-resolution audio production. At the heart of the conversion process is a multibit design with a 5-bit delta-sigma modulator, ensuring a musical and accurate sonic result. The integrated microphone preamp, featuring 3 dB stepped analog gain and digital control with 0.25 dB precision, stands out for its transparent sound and exceptional dynamic range, between 118 and 121 dB, with an equivalent input noise floor reaching –130 dB, making it one of the quietest and most transparent converters available.

The AX24's versatility extends to remote control, enabled via RS-422, USB, and Ethernet interfaces. Leading consoles and DAWs can display the preamp controls directly on their channel strips, ensuring seamless integration into existing systems. The unit is also ideal for stage box applications or installation in machine rooms, thanks to its full remote operability and DADman software available for both Mac and PC.

In terms of digital interfacing, the AX24 supports a wide range of professional formats including MADI, AES3, S/PDIF, TDIF, and Pro Tools. The MADI interface, in particular, enables the transfer of all PCM formats up to 192 kHz, as well as DSD and DXD, and can be configured in daisy chain mode to connect multiple converters on the same MADI line, managing up to 64 channels in blocks of eight with ultra-low latency. The unit also supports external synchronization via AES11, Word Clock, Super Clock, or video signals in PAL, NTSC, and SECAM formats. A visual alarm system alerts the user in case of digital sync loss, enhancing the reliability of the entire recording setup.

The AX24 stands out for its musicality, technical precision, and outstanding flexibility. Every element of the system is designed to offer maximum control and flawless audio quality, making it an essential tool for anyone seeking excellence in audio conversion, whether in recording or professional mastering environments.
