AX24 | 192 PHD is a dedicated model of the AX24 Converter system family. AX24 | 192 PHD comes complete with an interface card connecting directly to the Avid Pro Tools digital audio workstation connected via standard DigiLink. Cables to HD Core or Accel Core cards. Pro Tools recognizes the AX24 | 192 PHD converter and controls all input and output functions, clocking, routing and other settings. One AX24 | 192 PHD can provide up to 8 channels of analog to digital and digital to analog conversion. Up to four AX24 | 192 PHD converters can be connected via the DigiLink expansion port for a total of 32 channels of analog to digital and digital to analog conversion. Additional control of the AX24 | 192 PHD e.g. gain setting of the optional build in mic preamps is provided via the DADman control applications which runs on all MAC OSX and Windows platforms.
AX24 | 192 PHD is a truly plug and play system which provides you with the legendary natural DAD converter sound for your Pro Tools rig. AX24 | 192 PHD automatically provides signal latency identical to that of the AVID 192 I/O™ for accurate delay compensation within ProTools - no manual delay adjustments are required.
The AX24 | 192 PHD contains one Primary and one Expansion DigiLink port. AX24 | 192 PHD supports full channel count at sample rates up to 192 kHz. You do not lose half of your channels at higher sample rates. Pro Tools users can now benefit from the precise internal master clock of the AX24 converter for very low jitter and low distortion of digital signals

AX24 | 192 PHD models.The following 5 dedicated models are avaliable.

  • 8 Line AD and 8 DA analog I/O
  • 8 Mic/Line AD and 8 DA analog I/O
  • 8 Line AD analog inputs
  • 8 Mic/Line AD analog inputs
  • 8 DA analog outputs .

The models are limited to the 192 kHz sample rate, and to have only one digital interface - the DADI/O-PHD module. If more digital I/O modules are needed like MADI or AES3 or if the sample rate need to be 384 Khz, the unit can be license upgraded to a standard AX24.

converter system unit. Additionally the two internal Firmware EPROM's of the AX24 basis unit have to be changed to version 2.20 in order to recognise the card.

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 the quietest and most transparent converter on the market. The DADman control utilities, provides various control interfaces for MAC and PC. This enables the Mic pre controls can be represented on the channel strip of major consoles, and various DAW including ProTools HD
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.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.


The ultimate choice for High Reliability and High Performance Audio Routing and Audio Processing.

Designed for flexibility, reliability, easy operation and maximum redundancy.

Comprehensive range of facilities for signal control, signal monitoring and signal handling, inclusive a varity of DSP functions and protocol interface to third-party routers.

Reliability, innovation and years of expirience.
