General Description
The AX32 Converter System is a modular unit with a basic digital I/O and processing card. The chassis has
eight card slots where up to six 8 channel analogue input or output cards can be installed.
The chassis can be fitted with one or two power supplies. One power supply is sufficient when using a
maximum of 5 cards. In that situation, it is possible to have a second power supply installed as a redundant
power supply. When 6 cards are installed, two power supplies must be installed in order to keep the
temperature in the power supply at a reasonable level. An AX32 with 6 cards can operate on one power
supply only, so the AX32 will not go down if one of the power supplies fail. However it is not recommended
to leave the AX32 operating like this for several days as the lifetime of the remaining power supply may be
reduced considerably.
AX32 has a slot for an optional I/O mini module. The module can be a dual optical MADI I/O interface using
“Small form-factor pluggable” (SFP) transceiver modules, providing 2 x 64 optical MADI channels.
The IP audio option for AX32 is established by installing a Dante™ Brooklyn II module internally in the unit.
The IP audio will interface to the Ethernet connector via an internal Ethernet switch on the basic digital I/O
and processing card. The switch operates as a bridge between the two RJ 45 Ethernet connectors on the
rear panel and the internal controller and the Dante™ Brooklyn II module. In normal operation both
connectors can be used for connecting to Ethernet, and as switch to expand the connection to other units.
When the IP audio option is operating in redundant mode the two connectors have redundant IP audio
streams. In this case the control of the unit is made via network connector 1.
AX32 is a remote controlled unit. The control interface is the Ethernet connector and the DADman software
controls the units via Ethernet. Some front panel control of the units is also possible.
In addition to the AD/DA conversion and digital I/O functionality, AX32 provides a very powerful router
matrix functionality as well. All input signals can be patched to one or more output interfaces on a mono
channel basis. So in fact the AX32 is also a digital patch bay.
