Multi-Channel Audio
Audio Input/Output Modules
In addition to embedded audio, provided as a standard feature on the MAXX-2400HD, an analog audio and a digital audio I/O module are available as optional accessories. Each provides for a total of eight audio channels on XLR-3 connectors, for each video input or 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 height), which connects to the server chassis with a 1-meter, 68-pin cable included with the DXP-2. The DXP- 2 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. They 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.
When used in combination with DXP-2, the MAXX-2400HD 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 remains 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.
