NEXO NXAMP 4X1 Owner's Manual - Yamaha Commercial Audio

GENERAL DESCRIPTIONIt is mandatory to have a galvanic isolation between these signals and anyanother equipment. Thus, either the target equipment should present isolated GPIOsystem, or the signal should goes through small signal relays to guarantee that the NXAMPGPIO 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 of32 mA for each outputs.Expansion slot blockThe expansion slot uses unique 80 pins connectors that will allow the user to simply fit aexpansion board into the amplifier. At the moment, the only expansion board available isthe NXES104 Ethersound board (compatible with the ES-100 standard, offering fullremote control from a computer running ES monitor by Auvitran application, and 4channels of 24 bits 48 KHz audio).NEXO expansion slot form factor is not compatible with the Yamaha mini-YGDAIform factor. Thus, Yamaha mini-YGDAI card cannot be fitted inside NXAMP4x1 PoweredTDcontroller.PAGE 29 OF 80
