MENU DESCRIPTION
Repressing A & B buttons while the NXAMP4x1 is starting (this last 20 seconds). At the end
of the boot time, you will hear the output relays moving. You should then see the two up
and down arrows surrounded in the above drawing. This means that you can change
between any speaker setup by turning the wheel. Select the appropriate setup by pressing
“OK” (button B) or press the button A to go back to current setup without changes.
N.B.: You can reset the unit without powering off by simultaneously repressing buttons A,
B & SELECT CH1 at the same time for at least 3 seconds.
Note: Selecting a new family will set all parameters to factory default settings.
N.B.: “FLAT –NO PROTN.” Is the default setup; it means no EQ (Flat) and no protection
(No protn.) for the speakers but of course amplifier protections will still work.
Adjusting Volume
The volume of each channel can be adjusted from the Volume menu (unit is dB). Bellow is
a picture of this menu.
The volume setting for each channel can always be clearly seen from the front panel
surrounding LED (white/blue) around each mute button. The position of the LED gives the
value of the volume, like it would be for a traditional analog volume pot. The picture bellow
gives the attenuation value for each LED.
