"For high end mastering we found the AX24 to be the only choice! The AX24 is by far the most neutral converter we have tried, and we have tried them all!" Lehnert Kjeldsen, Master Touch ApS
"I just can't believe the musical quality of the sound from your design. It never disappoints!! It seems to me you have an extraordinary challenge if improvement on the AX24 is possible. There is nothing about the sound your design produces that leaves me wanting or imagining that more or better is possible.
The sound through your micpres is of the same calibre as the best of my stand alone boxes. Your preamps are one of my "go to" sounds." Rob Dziedziczak, Electronic Pencil

DAD US Retail Price List
The AX24 Converter System is Musical, Correct, and Flexible. AX24 allows you to config the number of line and Mic channels that you need at the sample rate currently used. Analog in and output channels can be expanded in pairs of two. Especially configurations like 2 or 4 analog input channels and 6 analog output channels are very suitable for mastering or multi track productions where only few analog input channels are used simultaneously but monitoring in 5.1. is essential.
24 bit PCM sample rates up to 384 kHz, DXD and DSD. AX24 is based on the Digital Audio Denmark high quality multi bit converter and modulator design, using a 5 bit delta sigma modulator. AX24 offers A/D and D/A conversion in PCM up-tp 384 kHz, DSD at 64fs or 128fs and DXD at a sample-rate of 352.8 kHz. AX24 covers applications for music recording as well as mastering and monitoring in DSD.
Mic pre with analog gain in 3 dB steps and digital gain with 0.25 dB accuracy is available for AX24 providing a sonically very transparent integrated Mic pre and ADC design. The Dynamic range is between 118 & 121 dB.
The key advantage of the DAD “integrated into the converter” mic pre is the elimination of gain stages and noise. Typically a mic pre (analog) is wired via XLR to the (analog) input stage a converter. The mic pre will need to deliver a signal of somewhere between +18 to +21 dBu to drive the input stage of any A to D converter to full scale 0 dBfs. The mic pre has an output stage to achieve normal output levels and the converter has yet another analog input stage.
With the DAD Integrated Mic Pre system, the mic pre is actually inserted within the converter input circuit itself and requires only 1.45 dBu of analog input gain to generate a full 0 dBfs signal. The 18+dB of gain required in the typical out board system is eliminated, avoiding at least 15db of gain and avoiding a whole lot of circuitry. By avoiding this unneeded gain, DAD lowers noise figures to -122dB, an unheard of number in converters. DAD’s significantly higher audio quality when using microphones offers an audible step up in transparency and clarity over other configurations. In addition, the DAD mic pres can be integrated, via supplied DADman software, to appear within ProTools® computer screens so make this integration seamless and easy for the user.
Full remote controllable via USB or Ethernet. AX24 is ideally suited for stage box applications or machine room environment, due to the powerfull remote control. The remote control interface is RS-422 nad can be adapted to USB, Ethernet or other data formats providing a very flexible control structure.
The DADman control utilities (download), provides various control interfaces for MAC and PC. This enables the Mic pre controls to be represented on the channel strip of major consoles, and various DAW including ProTools HD.

Modular Interface structure. All DAD-I/O modules are available for AX24 providing interfacing for the most used PCM formats up-to 96 kHz. Additionally the 8 channel AES3 module can interface 192 kHz and 384 kHz on a multiple wire interface.

The MADI interface, supports all the sampling formats of the AX24, and is an extremely powerfull and capable interface which input and output all the PCM rates up-to 192 kHz as well as DSD and DXD. The interface can be configured to operate in a daisy chain for connecting more converters to the same MADI link. The MADI interface and the converter can be set to access any of the up-to 64 MADI channels in any confuration in blocks of 8 consequetive channels. All "unused" channels are linked through the interface with very low latency of only a few samples.
External synchronisation to AES 11, Word Clock, Super clock or video (PAL, NTSC, SECAM) . The built-in PLL circuit is able to correct for minor variations in the external sync clock signal, giving a very stable adaptation to the external synchronisation signal.
Sync alarm. If a digital output is chosen with the DA source button, and the digital input for some reason is out of synchronisation, the red Sync alarm LED will blink. This function is available to secure that the whole recording system is synchronised. The function can be turned off in the system menu.
