PAGE 18 / 80 NXAMPMK2 USER MANUAL
As explained in Power outputs section, the amplifier outputs are cabled as on the following graph:
In some cases, the NXAMPmk2 optimizes the output pinout by swapping CH1 with CH2 (and CH3 with
CH4) depending on speaker presets used
Output mode section to change this setting).
To understand the output mode usage, we will take 3 specific speaker configurations for CH1 and CH2
and see on which speakON speakers must be connected and how output mode setting is used.
As a reminder, NEXO speakers are mostly cabled as following: Subwoofers on 1+/1-, Passive speakers on
2+/2- and Active speakers (2 channels) with LF on 1+/1- and HF on 2+/2-.
CONFIGURATION WITH TWO SPEAKERS 2+/2-
In that case, we will take two P12 speaker in passive mode (taking the signal from 2+/2-), recalled on
amplifier CH1 and CH2.
If nothing is done in this configuration, the cabling is not straight forward, CH1 is taken from speakON B and
CH2 from speakON A. This crossed cabling can be very confusing when using the amplifier. This is where
output mode is used.
S
D
(taking signal from 2+/2-) are next to each other.
With this setting, the amplifier crosses CH1 and CH2 just before amplifier stages. Of course, the channel
arrangement on touchscreen and NeMo stays unmodified.
As it can be seen on the following graph, CH1 is now taken from speakON A and CH2 from speakON B,
which is way easier to understand and use.
