User manual

GENERAL DESCRIPTION
• 4 x 5 Volts outputs
• 8 x GND (ground) signals.
The pin out of these signals is given bellow:
It is mandatory to have a galvanic isolation between these signals and any
another equipment. Thus, either the target equipment should present isolated GPIO
system, or the signal should goes through small signal relays to guarantee that the NXAMP
GPIO will be isolated from the other equipment.
The maximum current available on the GPIO port is the following:
• Maximum 200 mA drawn from the totality of the +5 V outputs.
• Maximum 200 mA drawn from the totality of the GP Outputs, with a maximum of
32 mA for each output.
Expansion slot block
The expansion slot uses unique 80 pins connectors that will allow the user to simply fit an
expansion board into the amplifier. At the moment, there is two expansion boards
available, the NXES104 Ethersound™ board and the NXDT104 Dante™ board.
The NXES104 is compatible with the ES-100 standard, offering full remote control from a
computer running ES monitor by Auvitran application, and 4 channels of 24 bits 48 KHz
audio, from an ES network or from a PC computer through a LAN network using the
Auvitran ASIO streamer technology.
The NXDT104 is compatible with the Dante™ standard, offering full remote control from a
computer running ES monitor by Auvitran application, and 4 channels of 24 bits 48 KHz
audio from another Dante™ device including a PC or Mac computer through a LAN network
using the Dante™ Virtual Soundcard technology.
