PAGE 14 / 80 NXAMPMK2 USER MANUAL
A: POWER OUTPUTS
The NXAMPmk2 uses four NL4 outputs to connect the speakers.
Outputs can be bridged two by two independently, CH1 with CH2 and CH3 with CH4 (CH3/4).
As shown on the following graph, the amplifier CH1 is always connected to SpeakON A 1+/1-, and amplifier
CH2 is always connected to SpeakON B 1+/1-. Furthermore, both SpeakON are crossed, so CH1 is also
available on SpeakON B 2+/2- and CH2 on SpeakON A 2+/2-. When bridged, CH1/2 bridge is connected
where CH1 was. The structure is symmetrically the same for CH3 and CH4 with SpeakON C and D.
NOTE
In some cases, the NXAMPmk2 optimizes the output pinout by swapping CH1 with CH2 (and CH3 with
CH4) depending on speaker presets used Speaker cabling & output mode
section precisely describing this process, and also presenting typical speaker cabling cases.
In all cases, please check front panel indication to know where to connect your NEXO speaker. Checking
the output patch section explains where to find this information.
To help you connect seamlessly the NXAMPmk2 to your NEXO speakers, an automatic Digital Patching
Unit (reference DPU) is available. See Digital Patching Unit section.
WARNING!
When used in bridge mode, never touch (or short-circuit) the unused pins on the output NL4 as some high
voltage can be present.
Please check the speaker impedance before connecting to the NXAMPmk2.
WARNING!
The NXAMPmk2 works with output load down to 2 Ohms in four channels mode or down to 4 Ohms in
bridge mode.
