Before you start
Place your AX64 on a hard and dry surface or mount it into a 19” rack, and leave plenty of room for ventilation.
In order to meet the EMC requirements of directives EN 55032 and FCC 47 CFR part 15, and in order to obtain
the highest performance of the AX64, you must use good quality correctly shielded cables for all external
connections when installing AX64. For the power connection, a normal unshielded power cable with a proper
protective earth conductor can be used.
Make sure that your sound system is at a safe volume level.
Mechanical installation and low fan noise
AX64 is fitted with two very quiet fans to ensure optimum operating temperature. The fans are temperature-
controlled, i.e. the rotation speed, and thereby noise, is dependent on the temperature inside the AX64. The fan
is hardly audible during normal operation, assuming the MTRX II is installed correctly.
The optimal air flow is through the ventilation openings in the front panel to the rear of the unit. When the unit
is installed, considerations have to be made to ensure proper air circulation for the air leaving the rear of the
unit. The speed of the low noise fan will be increased automatically to keep the internal temperature low if there
is insufficient airflow. If the internal temperature exceeds 60ºC / 140ºF a temperature alarm will appear in
DADman and is indicated via the red error LED on the front panel.
Accessing the AX64 cards.
It is not necessary to open the AX64 during installation, unless you need to add DAD expansion cards or module.
The AX64 cards and module options can be installed by removing the lid of the chassis. The chassis provides 8
card slot positions where cands can be installed. The mini I/O module is mounted on the Main board of the
converter. Cards and modules should not be removed or changed without consulting either NTP Technology or
an authorised DAD representative.
Network configuration
AX64 is equipped with two Giga Bit Ethernet connectors and internally an Ethernet switch, a controller part and a
part for the IP Audio option powered by Dante™. The network connectors can operate as two “parallel”
connectors for the internal switch, or as dual connectors for redundant IP audio operation. In this case
controlling the unit is done via Net port 1. AX64 has two to three different IP addresses. One for the unit control
via DADman and one or two for the IP audio in respectively single or redundant mode. The network
configuration is managed separately for the controlling interface and for the IP audio interface, and can have a
different configuration from the controlling interface. The controlling interface is used for controlling AX64 from
DADman and the IP audio interface is used for interfacing Dante IP audio in a network. The factory default setting
of the IP address of the controller port of the AX64 is 10.0.7.20. The IP address can be changed manually via
DADman or it can be set to be automatically assigned by a DHCP server/router in the network. If needed AX64
can be set in recovery mode with a the fixed factory defined IP address 10.0.7.20 and IP discovery via DHCP. This
is described in the Reconfig section of this manual.
Control software installation
Computer recommendation
The DADman control program operates on any Windows or MacOS based computer, and is
frequently maintained for interoperability with the latest OS versions.
Program installation
This section will take you through the installation procedure for the DADman computer control program.
