9.3. NXA series detailed view, device channels
The detailed view of a NXA device displays the configuration of the unit's 4 or 6 channels (depending on
model). Each channel offers the following parameters and settings:
9.3.1. INPUTS
First find the input selection activated for the channel in question, and their relative mixing levels. Here is
a picture of the matrix mixer for each unit channel.
With a double click on the knobs, each input can be activated (white knob) or
muted (grey knob) in the corresponding mixing channel. The knob setting (click,
hold and drag the mouse up / down) defines the level of each input in the mix.
In the example on the right, the channel mix includes the internal generator
(maximum level, 0 dB), input 1 (-24.7 dB), input 2 (-15.3 dB), input 5 (0 dB) and
input 6 (-5.3 dB).
9.3.2. VOLUME, SOLO, MUTE, POLARITY
Volume fader and additional controls:
 VOLUME: channel volume, adjustable from -infinity to 0 dB. There are two
VU-meter bargraphs to the right of the channel fader: the left bar displays the
channel input signal level and the right one the output signal level of the same
channel after processing.
 SOLO: mutes all device channels except those whose SOLO function is
enabled.
 MUTE: mutes audio for this channel.
 POLARITY: allows the input signal phase to be inverted (180 degrees shift).
9.3.3. CROSSOVER
The CROSSOVER section contains the FILTER TYPE and FREQUENCY parameters for each of the
two filters (low-pass and high-pass) composing the crossover. It splits the audio frequency spectrum in
two parts, creating the two bands generally used in two-way speakers.
 FILTER TYPE: allows you to select the crossover filter type. You can select one of the following
filter types.
Butterworth 6, 12, 18 or 24dB/oct
Bessel 12, 18 or 24dB/oct
Linkwitz-Riley 12 or 24dB/oct
 FREQUENCY: is composed of a potentiometer and a
numerical value to adjust the filter cut-off frequency
within the 20Hz - 20kHz range.
