GENERAL DESCRIPTION
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 outputs.
Expansion slot block
The expansion slot uses unique 80 pins connectors that will allow the user to simply fit a
expansion board into the amplifier. At the moment, the only expansion board available is
the NXES104 Ethersound™ board (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).
NEXO expansion slot form factor is not compatible with the Yamaha mini-YGDAI
form factor. Thus, Yamaha mini-YGDAI card cannot be fitted inside NXAMP4x1 Powered
TDcontroller.
