NEXUS Digital Audio Card XETR
The XETR AES/EBU boards combine four stereo digital inputs and four stereo digital outputs on one NEXUS board. Versions with only inputs and outputs are available; versions with XLR or BNC connections offer great structural flexibility.
NEXUS – XETR – The concept:
XETR series cards offer four 2-channel AES/EBU inputs and outputs, each with its own sampling rate converter. NEXUS networks support the transparent transmission of AES additional data (CUVZ) over the network, allowing the inputs and outputs of XETR cards to be used to connect AES intercom systems or for other purposes.
Furthermore, the combination of AES/ EBU inputs and outputs on one board allows an input clock that is asynchronous to the NEXUS system to be passed through unchanged to the corresponding output, while the input's sample rate converter only adapts the clock to the system clock on the NEXUS side. Of course, the entire NEXUS network can also synchronize its system clock to each of the inputs.
XETR cards are available with XLR or BNC connectors. Inputs and outputs are arranged on separate front panels and can be placed separately within a base unit. It is also possible to operate only inputs or outputs.
NEXUS – XETR – Features:
Available with XLR or BNC connectors This module can optionally be supplied with different front panels, the electrical conversion remains the same. The XLR versions are available for balanced lines and BNC for unbalanced cabling, as well as a 4HP wide front panel. (When using both the transmit and receive functions, a second front panel is used in both versions, which is connected to the circuit board via a ribbon cable.)
Support of S/P-DIF signals Since the professional AES/EBU signal and the consumer format S/PDIF differ only in the electrical level, the XETR cards offer the possibility to select the type of input or output in the settings. In this way, both formats can be received and transmitted.
Adjustable digital gain in inputs and outputs For input signals with known under steering, the level can be digitally amplified by 20 dB. A reduction is also possible. A switchable limiter protects against overload.
Sampling rate converters in all inputs and outputs The sample rate converters in the inputs can be switched on manually or operated in auto mode; the board automatically detects whether the incoming frequency corresponds to the NEXUS system clock. A sampling rate of 44.1/48 kHz; 88.2/96 kHz or 176.4/192 kHz can be set for each output. In addition, the outputs can also be synchronized to the paired input of the same module.
Transparent transmission of additional data in the AES3 data stream The NEXUS network is able to transparently transmit an AES3 data stream including the additional data. If no data is available in transparent mode, NEXUS internal data is output. If additional data is transmitted on only one channel, it is transmitted to the other channel.
