Multi-Channel Audio Module
Audio Input/Output Modules
In addition to embedded audio and 2 channel analog audio I/O provided as a standard feature
on the MAXX-1200, a digital audio I/O module is available as an optional accessory. It
provides for a total of eight audio channels on XLR-3 connectors, for each video input and
output.
DXP-2 Digital Audio Module
The DXP-2 Digital Audio Module provides 8 audio channels in AES/EBU format, for each video
input or output. It is housed in a 2-RU rack-mount enclosure (3½” – 88mm high), and connects
to the main server chassis with a 1-meter, 68-pin cable, included with the DXP-2. The module
is self-powered from AC mains, and contains all audio circuitry. (It is not a connector ‘break-out
box’.)
DXP-2 Digital Audio I/O Module
Audio outputs from the DXP-2 duplicate the embedded digital audio contained in the video.
Audio outputs are at a fixed 48 KHz sample rate, and are normally referenced to video genlock.
Digital audio input signals should also be at 48 kHz, and be derived from video genlock.
The MAXX-1200 server, used in combination with DXP-2, can record, store, and play
compressed or specially-encoded digital audio such as Dolby®-E, AC-3, or DTS®, using 360
Systems’ Bit-for-Bit® technology. The output data stream will be identical to the input data.
The DXP-2 contains dual redundant power supplies, operated from two separate AC mains
connections. Either power input can be lost, with no effect on audio throughput. Two blue
LEDs indicate operation of the power supplies. There are no other controls or adjustments on
the DXP-2.
