Digital Audio Denmark

The philosophy of DAD is to provide extreme audio quality at all sample rates and offer a product that can evolve and grow with the end user. The AX24 line is the result of an innovative development which provides major improvement in AD and DA conversion and signal capture utilizing top industry standards like sample rates to 384 kHz including DXD and DSD.

AX24 Audio Converter

The AX24 Converter System is musical, correct, and flexible. AX24 allows you to configure the number of line and Mic channels that you need. 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 multitrack productions where only few analog input channels are used simultaneously but monitoring in 5.1 is essential.

The AX24 features 24 bit PCM sample rates up to 384 kHz, DXD and DSD and is based on the Digital Audio Denmark high quality multi bit converter and modulator design, using a 5 bit delta sigma modulator.

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 and the Mic pre equivalent noise floor is at -130 dB. AX24 offers an impressive dynamic range, making it one of the quietest and most transparent converters on the market.

Full remote controllable, 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 and can be adapted to USB, Ethernet or other data formats providing a very flexible control structure.

Thanks to MIDI remote controllability, Mic Pres can be controlled directly within Pro Tools or from the ICON D-Control and D-Command. Many different 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.

External synchronisation runs over 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.

DAD I/O HD

The DAD I/O HD allows a connection between Pro Tools HD cards and AX24 interfaces equipped with MADI input/output. DAD HD I/O features two Digi links and two MADI I/O's for a total of 64 channels @ 96kHz or 32 channels @ 192 kHz. Within ProTools the DAD HD I/O interface box shows itself as two Avid digital 192
I/O boxes.

With MADI I/O cards mounted in the AX24’s, multiple AX24’s can be daisy chained into one MADI link. One MADI link can be used for 64 channels @ 48kHz, 32 channels @ 96kHz and 16 channels @ 192kHz audio.

Features:
- 2 Primary port interfaces (32 channel @96 kHz each) to a Avid Pro Tools|HD® card
- 2 Coax MADI I/O ports
- Word or SuperClock input for synchronization
- USB interface for future firmware updates
- Latency generated by the DADI HD IO is limited to 1 sample for MADI Out and 1-2 samples for MADI In
- Each MADI port offers:
56 or 64 MADI digital inputs and outputs at up to 48kHz,
28 or 32 MADI digital inputs and outputs at up to 96kHz,
14 or 16 MADI digital inputs and outputs at up to 192kHz
