The high-density output card for stereo line signals up to +15 dBU

"Stereo version" of the outstanding XDA+ converter card

With a dynamic range of 120 dB (A) at a maximum output level of 15 dBU, this NEXUS board is a space-saving replacement for XDA+ when it comes to stereophonic signals.

High-density card with 16 audio channels - large quantities of outputs at a low price

This board offers high channel density, which accommodates a large number of required inputs, especially in situations requiring portability or low weight.

Quality feature: Output transformer for every budget

Despite the compact circuit design, each channel is transformer isolated. The input pairs (1/2, 3/4, etc.) share a common ground potential, since the module is intended for the connection of stereo and multi-channel devices. Stage Tec's transformer-insulated outputs have clear advantages over conventional circuits: They are insensitive to magnetic fields and have a lower distortion factor, especially at high and low levels and at low frequencies. They also offer high symmetry, galvanic isolation and a lower output capacitance.

"Ground Lift" disconnectable ground connection

The connection to the common ground can be cancelled separately for each input pair (1/2, 3/4, etc.). This is done via DIP switches, which prevent the connection of the screen line to the internal analog ground.

Playback of high channel numbers in distributed loudspeaker systems

In live or theatre situations, production or staging may require a large number of speakers to be fed with signals. With 16 output channels, the HXDA card offers many playout paths in a small space and is particularly convincing in such situations. There is a great need for outputs, especially at events with a complex sound concept such as delta stereo and the use of effect loudspeakers, as is usual for musical or film productions. For productions in the studio or on stage with orchestras or other groups of many musicians, additional output paths are increasingly required for headphones to perform in sync with pre-produced content. Often there is not much room for technology to fit into expansive sceneries and between lighting and effects technology. In switching rooms for radio operation, there is also usually no need for large XLR connections, especially in such large numbers, because the connections are made via multicore cables with D-Sub connectors. In combination with a 1U NEXUS base unit, which offers space for four HXDA cards in addition to one CPU and one fiber optic board each, 64 channels can be played out with the size of an ordinary 19" device.
