Page 4: Safety Precautions
Please check the NEXO Web site nexo-sa.com to get the most up-to-date version of this manual. Ensure you are aware of the safety rules applying to rigging, stacking, or installing on tripod or speaker stand.
Page 5: Precautions
If the power cord or plug becomes frayed or damaged, or if there is a sudden loss of sound during use of the device, or any unusual smells or smoke should appear to be caused by it, immediately turn off the power switch, disconnect the electric plug from the outlet, and have the device inspected by qualified NEXO service personnel.
Page 6: Connections
Remove the power plug from the AC outlet when cleaning the device. The performance of components with moving contacts, such as switches, volume controls, and connectors, deteriorates over time. Consult qualified NEXO service personnel about replacing deflective components. HANDLING CAUTION When turning on the AC power in your audio system, always turn on the device LAST, to avoid speaker damage.

Page 15: C: Air Exhaust
C: AIR EXHAUST Do not obstruct the air exhaust at the back of the nanoNXAMP4 and leave at least 80 mm behind the unit for air flow. The air intakes are on both sides of the unit therefore a 25 mm clearance is needed on at least one of the two side of the unit.
Page 16: D: S/Pdif Interface
D: S/PDIF INTERFACE The nanoNXAMP4 features a S/PDIF Input and Output interface on RCA Phono sockets that can be used to connect to digital audio sources (like TV receiver or network streamer) or output some of the nanoNXAMP4 Analog Inputs, Input Mix or Area Mix to other devices (like other nanoNXAMP4 units in daisy chain).
Page 17: F: Power Amplifier Outputs
F: POWER AMPLIFIER OUTPUTS There are four power amplifier outputs on the nanoNXAMP4, bridgeable (Bridge Tile Load : BTL) two by two to increase the power on the resulting output. WARNING! The exclamation point printed next to the output terminals of the amplifier is, in addition to the CLASS 2 WIRING test, intended to alert users to the risk of hazardous voltages.
Page 18: G: Mains Connectors
Connecting cables to the supplied female output connector is illustrated below. G: MAINS CONNECTORS The nanoNXAMP4 can accept Mains from 100 to 240 Volts, both 50 to 60 Hz, thanks to its high efficiency active PFC (Power Factor Correction) system.

Page 23: Remote Control Software Description
REMOTE CONTROL SOFT ARE DESCRIPTION NANONXAMP4 START-UP The nanoNXAMP4 startup is straightforward. Once all the wiring has been done and mains is present, the front panel STATUS LED is light up and the device is ready to be configured. To do so you must access the embedded webpage through the network port of through the Wi-Fi connection (default mode for nanoNXAMP4 Wi-Fi connection being Access Point mode).
Page 24: Wired Network Control Connection
2. Input: Allow to adjust input related parameters like level, gain, phase inversion, sensitivity (for Analog Inputs) and setup inputs mixes. 3. Area: The heart of the nanoNXAMP4 where the input (or inputs mixes) can be routed with priority input and compressor settings.
